Ape music
Comparison of spectrogram between APE and MP3 audio formats WAV format, as the standard of digital music file format, has too large capacity and is inconvenient to use. Therefore, we usually compress it into MP3 or WMA format. Compression methods include lossless compression, lossy compression and mixed compression. MPEG and JPEG belong to mixed compression. If compressed data is restored, the data is actually different. Of course, the human ear is indistinguishable. Therefore, if MP3 and OGG formats are restored from compressed state, there will be loss.
However, even if the APE compression format is restored, the original sound quality can be preserved without loss. Therefore, APE can be compressed and restored without losing treble texture. Of course, at present, only music CDs and tracks in uncompressed WAV files can be converted into APE format, while MP3 files cannot be converted into APE format. In fact, the compression ratio of APE is not high. Although the sound quality is well maintained, the compressed capacity is not much smaller. A 34MB WAV file, compressed into APE format, and about 17MB. For the whole CD, the capacity saved by compression is still considerable.
APE is actually a lossless compressed audio format. Huge WAV audio files can be compressed into APE by monkey's audio software. It is often used for network audio file transmission, because the compressed APE file capacity is less than half of the WAV source file, which can save transmission time. More importantly, the WAV file obtained after decompression and restoration of monkey's audio can be exactly the same as the source file before compression. Therefore, APE is called "lossless audio compression format" and Monkey's audio is called "lossless audio compression software". Unlike using professional data compression software such as WinZip or WinRAR to compress audio files, compressed APE audio files can be played directly. The monkey's audio will install an "in_APE.dll" plug-in in Winamp, so that Winamp can also play APE files. Similarly, foobar2000 and Qian Qian Listening can also support the playback of APE.
APE format related instructions:
1. change
APE can be carried out through foobar2000, monkey audio, and thousands of listeners. Among them, foobar2000 can convert APE into WAV and then into MP3, while Qian Qian can directly convert listening to songs.
To convert APE into MP3 with monkey audio:
1. Select Decompression, add the APE file to the list, and then click Process File to convert the APE into a WAV file, which is stored in the Output directory set in the options.
2. Install an MP3 encoder, such as LAME encoder, and copy the encoder file directly to the external directory under Monkey' s Audio.
3. Select compression, and then select LAME in the compression level option, so that the compressed WAVE file is compressed into MP3 by LAME encoder.
burn
APE downloads a plug-in named nxMyAPE.dll directly by burning it into a CD-ROM with a burner, and copies the file directly to the C: \ program files \ common files \ ahead \ audio plugins directory of the burning software Nero, so that Nero can identify the APE file and directly burn the APE into a CD-ROM.
identify
AutoCDtest software can detect whether the APE file you use is a pseudo APE file converted from lossy compressed audio files.
APE playback and format conversion
APE audio format is being loved by more and more friends because of its high-quality lossless sound quality. We can often see the download of APE audio files in BT publishing area. It's just that most of the APE files downloaded from the Internet are suppressed by the whole CD. How can I choose songs to play at will and separate the singles from them for preservation?
Music selection and playback
It is also convenient to play with cool dogs.
To play the APE file suppressed by the whole CD, you need the support of CUE file if you want to choose any music. The file records information such as the start time of each track of the disc. If the player used is Foobar2000, you can import the CUE file directly, and you can choose to play songs as long as the information in the CUE file is correct.
Qian Qian sounds very convenient, and you can recognize cue and ape formats without installing plug-ins. You can also edit file properties such as MP3.
If you use Winamp to play APE files, you can install a plug-in called Mp3CUE, so that Winamp can support CUE files. After unzipping the downloaded compressed package, run Setup.exe, select the installation path of Winamp, and click Next to complete the installation. Re-run Winamp, there will be an extra "Mp3cue" window (if [Alt+N] key is not pressed). When playing an APE file, you can directly double-click the list in the Mp3cue window to select any music.
Single song reduction
If APE is suppressed by the whole CD and there are corresponding CUE files, we can use the tool MakeAPL attached to Monkey's audio to convert CUE into several APL files, and then we can use Monkey's audio to restore the single to WAV or convert it into other formats. The specific operation method is as follows:
Click Start → Program → Monkey Audio →【MakeAPL to open the make APL operation window, click Create Link File (S), select the CUE file corresponding to the APE file, and click Open to find the generated APL file in the directory where the CUE file is located.
Open Monkey's Audio, select Decompress in the mode menu, click Add File in the toolbar, select the APL file to be restored and open it. Finally, click the [Decompress] button, and the software will automatically begin to decompress.
If you still don't understand, watch it again:
APE is actually a lossless compressed audio format. Huge WAV audio files can be "slimmed down" by the software Monkey Audio and compressed into APE. Sometimes it is used for network audio file transmission, because the compressed APE file capacity is less than half of the WAV source file, which can save transmission time. More importantly, the WAV file obtained after decompression and restoration of monkey's audio can be exactly the same as the source file before compression. Therefore, APE is called "lossless audio compression format" and Monkey's audio is called "lossless audio compression software". Unlike using professional data compression software such as WinZip or WinRAR to compress audio files, compressed APE audio files can be played directly. Monkey's Audio will install an "in_APE.dll" plug-in in Winamp, so Winamp can also play APE files.
Cut the crap and get to the point:
Click the down arrow next to the first icon below the menu bar, and a row of individual options will appear. The first item is "compression" and the second item is "decompression". Creating or extracting APE files depends on these two options. Compression means compression, which means WAV => ape; And decompression is decompression, that is, APE => Wow. If we want to compress WAV into APE now, select "compress". Next, we must choose the compression level. Press the down arrow of the second button, and four options will appear, namely "Fast", "Normal", "High" and "Ultra High", which respectively represent different compression levels. The "fast" level has the fastest compression speed and the largest file capacity, and so on. "Ultra-high" level has the slowest compression speed, but the highest compression rate. Then, you can add a single WAV or a WAV document to the entire folder through the third or fourth icon. The selected file will appear in the information bar below. At this point, press the first "compress" button again, and the software will start working according to the compression level you specified. The progress bar is located in the lower right corner of the software.
It is also convenient to restore APE to WAV. First, set the software to the "decompression" state. Just press the first icon button to select the corresponding item, and then press the button, and the software will automatically begin to decompress.
There is also a path problem, which is actually very simple. There is an "output ..." in the "OPATIONS" option. Click on it, and there is an "output location" on the page on the right side of the dialog box. The next two lines choose whether to switch to the original place or specify the path. To specify a path, select Export Specified Directory and click Browse.
[Edit this paragraph ]ape problem set
1. How to play audio files in APE format?
Answer: The monkey's audio installation package comes with an Ape plug-in for Winamp. After installation, you can use Winamp to place ape.
B with foobar2000, this recently popular player supports ape format.
2. For APEImage, can I choose music at will when playing?
Yes, but you need a suitable prompt file. Generally, the whole CD is compressed into an APE file with the corresponding cue file, which records the information such as the start time of each track of this CD.
You can open this cue file with text editing software, and the content is similar to the following.
Performer "matthew lien"
Title "Blood Wolf"
File "cdimage.ape" wave
~ ~ ~ ~ ~ ~ ~ ~ The following is the corresponding ape file name, which is the same directory by default.
You can add a path, such as "c:\music\cdimage.ape".
You can't make mistakes, otherwise it won't play normally.
Track 0 1 audio
Title "Flying Mouse Creek"
Performer "matthew lien"
Index 0 1 00:00:00
……
A.foobar can directly import cue files, and as long as the information in cue is correct, you can select songs and play them.
For winamp, it seems 2. The X I used can't be directly imported into cue, but there is a solution. There is a tool in Monkey's Audio to makeapl, the software for making ape (the installer has created a shortcut for it in the start menu), which can convert cue files into several corresponding apl files, each apl corresponds to an audio track, winamp supports apl, and everything is ok.
C Install a winamp plug-in named mp3cue, which enables winamp to support cue files.
Note: According to my own experiment, to use this plug-in normally, you should add a picture file to winamp playlist instead of adding a cue file like foobar. As long as there is a cue file with the same name in the directory, the plug-in can recognize the third line of cue:
File "xxxxxx" wave
As long as the main file name is the same as the image file, mp3cue ignores the extension.
3. How to convert ape into mp3?
In fact, the monkey's audio supports an external codec, which can directly complete ape->; Of course, mp3 conversion should also be set properly.
1. Download lame and copy it to an external directory under the installation directory of monkey.
2. Run the monkey'' audio and select Convert in the mode menu.
3. in the second button of the toolbar, select external-> crappy->; Configuration, fill in the parameters needed to compress mp3 here, and recommend it.
-alt- preset limit
(The bit rate is 220-270 kilobits/second, and the average bit rate is usually around 256 kilobits/second.)
or
-alt- default standard
(Bit rate180-220kbit/s-usually about192kbit/s on average)
Just a reminder, the compression speed of the first parameter is much slower, and the machine is relatively poor, which is quite time-consuming.
4. in the second button of the toolbar, select external-> crappy->; Lame, at this time, you can select the ape file to be converted, and then click the first button convert to realize APE->; It's mp3.
4. Can the wrong ape file be repaired? Or ignore it?
If the entire CD is pressed into ape and there is a corresponding prompt file,
1。 Use make apl (a gadget attached to monkey audio) to convert cue into several apl files.
2。 By adding these apl in Monkey, each track can be decompressed into a separate wav. Of course, the audio track containing the wrong part cannot be decompressed normally. In theory, no matter what kind of ape, as long as you edit the appropriate apl and set the wrong part as a separate track, you can keep the other parts to the maximum extent.
5. How to burn APE to CD?
Answer. Ape-> WAV-& gt； laser record
This is the most commonly used method, which is suitable for both APEImage and multi-file APE, but it is also the most tedious.
B. burn CD with EAC
The recording function of EAC directly supports APE format, which is now ape->; The most convenient CD mode, in the EAC menu tools->; Writing cd-r turns on the recording function of EAC.
1。 If you have a ready-made cue file, it will be easier. Just import the cue file directly. Please note that the path and name of the audio track file in cue must be correct. For more information about cue, please refer to question 2.
2。 If there is no cue file, the downloaded file corresponds to an ape for each track, which is similar to carving wav or mp3 files into CDs in nero. The import command is under the layout menu (it is generally recommended to use "Append files as new tracks (index 1)"), or drag and drop directly.
C. using APE plug-ins for Nero
After installing the ape plug-in for nero, you can drag and drop it in nero, just like burning a cd with wav and mp3.
Plug-in downloads the audio plug-in of Nero burning ROM at Mausau address.
Nero also has other audio plug-ins in all common audio formats.
How to install the plug-in: extract the plug-in DLL to the "... \Ahead\Shared\AudioPlugins" directory.
Nero version requires more than 5.5.9.0.
Note: There is a major error in this early version of Nero Ape plug-in.
If you use Nero to import CUE to burn APEImage-& gt；; CD, it seems that it can be burned normally, and the number of tracks and time display are normal. However, play the engraved CD-all tracks are the same as the first track!
If there are more than one ape-carved CD, everything is normal without this problem;
Please download the latest version;
If your machine is fast enough, install this plug-in and burn APE- > directly with nero. CD is also a good choice.

I introduction of APE format
APE is a lossless compressed audio format. Huge WAV audio files can be compressed into APE by "slimming" Monkey's audio software. Similarly, APE can also be restored to WAV through monkey's audio, and then burned to CD. It is often used for network audio file transmission, because the compressed APE file capacity is less than half of the WAV source file, which can save transmission time. More importantly, the WAV file obtained after decompression and restoration of monkey's audio can be exactly the same as the source file before compression. Therefore, APE is called "lossless audio compression format" and Monkey's audio is called "lossless audio compression software". Unlike using professional data compression software such as WinZip or WinRAR to compress audio files, compressed APE audio files can be played directly.
Second, ape players:
1, Foobar2000 (mainly recommended)
Foobar2000 is an audio playback software developed by Peter Pawlowski, the main developer of winamp. Peter Pawlowski left winamp's development team because he was not satisfied with winamp's development direction. Although the Foobar playback interface is simple, it doesn't have many skins like Winamp, which can provide very good sound quality, and it doesn't need an external sound plug-in like DFX like Winamp.
2、Winamp
Monkey's audio includes Winamp's APE playback plug-in. In the process of installing monkey audio, a plug-in "in_APE.dll" will be installed in Winamp, so Winamp can also play APE files.
3. Windows Media Player
APE can also be played after installing the corresponding plug-in.
Third, format conversion.
1. You can use EAC or other audio acquisition software to convert a CD into a Wav file, and then compress it into an ape through Monkey's audio.
2. You can also directly convert the CD into APE.
3, apes into MP3
APE can be restored to Wav by decompressing the monkey's audio, and then Wav can be directly compressed to Mp3 by the monkey's audio.
4.APE is directly burned into a CD with a burner.
Download the plug-in named nxMyAPE.dll (as shown below), and directly copy the file to the shared \audioplugins directory of the recording software Nero, or C: \ Program files \ Common files \ ahead \ Audio Plugins \, so that Nero can identify the APE file, and thus can directly record the APE to a CD.
[Edit this paragraph] Comprehensive performance of ]APE and its comparison with other audio formats.
APE can be converted into WAV files lossless. The whole ape can be converted into wav by monkey software. Then use Notepad to open the prompt and change it. Apes when they pass through the file. Whoa, whoa. You can do whatever you want now.
In fact, ape is a compressed audio, which is equivalent to a rar file, but rar can only be used after decompression, and ape can listen directly without decompression. Converting ape into wav is called decompression, and the decompression tool is Monkey or foobar.
The legendary ape to wav is lossless, because ape is called lossless compression. As for whether it hurts you, it's up to you. If it doesn't hurt, it doesn't hurt, because I feel like it's almost the same ~ ~ ~
By the way, the common tool for converting CD into ape is Monkey or foobar, and Monkey must be installed. If you want to make ape and a full-track cue, it is recommended to use EAC. Although there are many options on EAC, online introduction is very troublesome, but it is very simple to use, just set it casually. After all, I am not a professional in this field, and the sound quality is not bad when screwing around, hehe.
Comparison between APE and FLAC
In the field of audio compression, there are two compression methods, lossy compression and lossless compression! We often see the lossy compression of MP3, WMA and OGG. As the name implies, lossy compression is to reduce the audio sampling frequency and bit rate, and the output audio file will be smaller than the original file. Another kind of audio compression is called lossless compression, which is what we are going to talk about today. Lossless compression can reduce the volume of the audio file on the premise that 100% retains all the data of the original file, and the compressed audio file can reach the same size and bit rate as the source file after recovery. At present, lossless compression formats include APE, FLaC, WavPack, LPAC, WMALossless, AppleLossless, LA, OptimFROG and Shorten, while the common and mainstream lossless compression formats are only APE and FLAC. Let's compare these two lossless compression formats!
APE is m's audio, lossless compression format. The compression ratio of this format is much lower than other audio formats, but it can be truly lossless. At the same time, its open source characteristics have also won the favor of many music lovers. Among the existing lossless compression schemes, APE is a format with outstanding performance, satisfactory compression ratio and fast compression speed, which is widely used in China and has become one of the choices for many friends to exchange feverish music privately.
At present, among MP3 manufacturers based on domestic Teleaction ATJ 2097 decoding chip, there are manufacturers such as VX939 of Onda and C 133+ of Taipower Technology that support APE format!
FLAC is the abbreviation of Free Lossless Audio Codec, which is a very mature lossless compression format, and its reputation is not under APE! The source code of this format is completely open and compatible with almost all operating system platforms. Its coding algorithm is quite mature, and it has passed the rigorous test, and it can still play normally when the coding is destroyed. In addition, this format is the first lossless format widely supported by hardware. World-famous digital products such as Karma, car audio MusicKeg of sword dance and digital player of PhatBox can all support FLAC format.
At present, the walkman with flash memory chip rarely supports FLAC lossless compression format, but recently, a well-known domestic manufacturer TL-T 19 announced that it supports FLAC lossless compression format, which is the first movie MP3 supporting FLAC lossless compression format in China so far and one of the few flash MP3 supporting FLAC music in the world.
As explained earlier, lossless compression is to compress the audio file smaller without losing all the bit rate of the source file, which means that both audio formats can guarantee the lossless bit rate of the source file. But after all, the two compression formats are two compression algorithms. The following are the similarities and differences between the two compression formats:
Similarities:
First of all, the compression ratio determines the storage space occupied by lossless compressed files.
The compression ratio of FLAC and AEP is basically the same. The compression ratio of FLAC is 58.70%, while the compression ratio of APE is higher, which is 55.50%, both of which are nearly half the size of the source file.
Second, the coding speed tests the patience of users, and the sooner the better.
It is very commendable that the coding speed of FLAC and APE is almost the same, because their compression technologies are open source, and developers can learn from their different coding advantages for development. But at present, two lossless compression formats, WavPack and Shorten, have the fastest coding speed, but their non-open source limits their popularity.
Third, the support of the platform determines popularity.
Audio compression needs not only hardware support, but also software support, so it can be supported by more platforms, which means it is used by more users. FLAC and APE do very well in this respect and are compatible with all system platforms. Now, whether you are a Windows user or many versions of Linux, even if you are a big fan of Mac OS, you don't have to worry about not being able to use FLAC or APE.
Fourth, it has both open source features and technology is completely free.
The open source characteristics of the two technologies mean that any organization or individual can use these two compression technologies for free, and any organization or individual can modify and release new products based on these two technologies, which provides a strong guarantee for many MP3 manufacturers to reduce costs, and consumers can also buy lossless compressed audio and CD-level sound quality performances that are only supported by world-class MP3 (for example, iPod supports ALAC) at relatively low prices!
Difference:
1, self-correcting ability, who is more humane?
Many consumers have experienced the sonic boom of MP3 and then blamed it on the quality of MP3. In fact, a large part of the sonic boom is due to the slight damage of coding in the process of audio compression, which leads to the inconsistency between the data processed during decoding and the audio, leading to the sonic boom phenomenon. Bad lossless format compression can also lead to code damage. When dealing with this problem, FLAC will replace the lossy part with silence, while APE will handle it in the same way as the common lossy compression format, and replace the lossy part with sonic boom. This FLAC design is more user-friendly!
2. The optimized coding structure determines the decoding speed!
Because of the different coding methods, the decoding speed of the two lossless compression formats will be affected. Generally, the decoding speed of FLAC is 30% faster than that of APE, because FLAC only needs integer operation instead of floating-point operation, which occupies higher frequency and greater data processing capacity of the system. Based on this, universal hardware can completely realize real-time decoding.
3. Convenient access to resources means wider application and support.
No matter FLAC or APE, in terms of resource acquisition, it can be easily obtained through network search!
Through the above comparison, I believe many users have a deeper understanding of FLAC and APE. From a technical point of view, FLAC is obviously superior to APE, because FLAC is the first open source lossless compression format recognized by the world, and top developers all over the world have developed and improved FLAC for free. At the same time, FLAC has extensive hardware platform support. Almost all portable high-end decoding chips can support music in FLAC format. The third advantage of FLAC is that excellent coding makes hardware only need simple integer operation when decoding, which will greatly reduce the occupied hardware resources! However, the two open technologies are highly complementary, and neither side can completely surpass the other!
