Basic information
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 can reduce the volume of the audio file on the premise of 100% retaining 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, TTA, TAK, LA, OptimFROG and Shorten, while common and mainstream lossless compression formats currently include APE, FLAC, TTA and Tak.
APE format
APE is one of the popular digital music file formats. Different from MP3 lossy compression, APE is a lossless audio compression technology, that is, when you compress the audio data file read from the audio CD into APE format, you can restore the file in APE format, and the restored audio file is exactly the same as before compression, without any loss. The file size of APE is about half that of CD, but with the popularity of broadband, APE format is loved by many music lovers, especially for friends who want to transmit audio CDs through the network, APE can help them save a lot of resources. [ 1]
APE is a lossless compression format provided by monkey audio. Monkey'sAudio provides Winamp plug-in support, so this means that the compressed file is no longer a simple compressed format, but an audio file format that can be played like MP3. The compression ratio of this format is much lower than other formats, but it can be truly lossless, so it has won the favor of many enthusiastic users. Among the existing lossless compression schemes, APE is a format with outstanding performance, satisfactory compression ratio and fast compression speed.
As the standard of digital music file format, WAV format is too large and 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 audio software. 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 by Monkey'sAudio can be exactly the same as the source file before compression. Therefore, APE is called "lossless audio compression format" and Monkey'sAudio 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'sAudio 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 conversion can be heard through foobar2000, monkey audio and Qian Qian. 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 can download a plug-in named nxMyAPE.dll through the burner and burn it directly into a CD, and copy the file directly into the shared\\audioplugins directory of the burning software Nero, so that Nero can recognize the APE file and burn it directly into a CD.
identify
AuCDtect software can detect whether the APE file you are using 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
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.
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 Saudio to convert CUE into several APL files, and then we can use Monkey's Saudio 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 BuildLink 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.
APE problem set
1. How to play audio files in APE format?
A: Monkey's audio installation package comes with Winamp's ape plug-in. After installation, you can use Winamp to place Ape.
B: With the recently popular foobar2000, ape format is supported.
C: With Cool Dog Music 20 10 and above, ape format can be played.
D: You can play it directly with Lefei Airplay without plug-ins.
E: It can be played directly with thousands of listening and playing software without plug-ins.
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. As long as the information in the prompt is correct, you can select songs and play them.
B: For winamp, there is a tool in Monkey's Audio to make software for APE (the installer has created a shortcut for it in the start menu), which can convert the cue file into several corresponding apl files, and each apl corresponds to an audio track. winamp supports apl, so everything is ok.
C Install a winamp plug-in named mp3cue, which enables winamp to support cue files.
To use this plug-in normally, you should add an image file to winamp playlist instead of adding a prompt file to 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.
-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.
In fact, the cool dog music player can directly convert APE into MP3. Cool dog can directly search and download your favorite lossless music single. After downloading, right-click the name of the single and a pop-up menu will pop up. The penultimate item is "conversion format", which can directly convert music in APE format into 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 Makeapl (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 track containing the error 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?
A, apes-> 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.
Use EAC to burn discs.
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. It will be easier if you have a ready-made cue file. 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 (generally, it is 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.
Ape related knowledge
I introduction of APE format
APE is a lossless compressed audio format. Huge WAV audio files can be "slimmed down" by the software Monkey'sAudio and compressed into APE. Similarly, APE can also be restored to WAV with Monkey's audio, and then burned to CD. 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 by Monkey'sAudio can be exactly the same as the source file before compression. Therefore, APE is called "lossless audio compression format" and Monkey'sAudio 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.
Pawlowski left the winamp development team because he was not satisfied with the development direction of winamp. 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. After loading the monkey's,
In the process of audio, a plug-in "in_APE.dll" will be installed in Winamp, so that 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. Monkey's audio 3.97
4.APE is directly burned into a CD with a burner.
Download the plug-in named nxMyAPE.dll (below) and copy the file directly to Nero's shared\audioplugins directory, or
C:\ Program File \ General
Files\Ahead\AudioPlugins\, Nero can recognize APE files, and thus can directly burn APE to CD.
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.
Specifically, I hope you can look at Baidu Encyclopedia and learn.
