As we all know, Windows comes with a recording software, which can record with a microphone or any sound from a computer sound card. But unfortunately, it can only be recorded for one minute at a time, and the final sound file is in WAV format, which has too much storage space and poor playback compatibility. At present, popular recording software (such as: Cool2. 1, Total Recorde, etc. ) is powerful, but either the installation operation is complicated or the registration fee is required. In fact, we can use some skills to make Windows "tape recorder" record long and small sound files (such as MP3 format) to achieve its "long" and "thin". First, easily extend the recording time of the "tape recorder". Usually, the recording time of a tape recorder is short (by default, it can only be recorded for 60 seconds at most). If the recording time is long, some flexible measures can be taken to realize it. 1. Empty record method. Before formal recording, press the record button to record blank, and then press the [Record] button after 60 seconds of automatic stop. Every time you press it, add 60 seconds, and then press the [Stop] key until the required recording time. When recording formally, drag and drop the recording slider to the beginning, and then press the [Recording] button to record normally. Finally, cut off the unnecessary parts before and after and save them. 2. Paste method. Clear the recording for 60 seconds, copy the recording content, then paste and insert, and the time will multiply. If there is not enough time, you can pull the recording slider to the end and copy and paste it until there is enough time (Figure 1). (Figure 1) 3. Deceleration method Clear the recording for 60 seconds. After the recording is completed, click the "Slow down" command in the menu bar repeatedly, and the time length will increase exponentially. When the time length is satisfied, drag the slider to the beginning, and then formally record, so that the recording length will easily exceed 60 seconds (as shown in Figure 2). (Figure 2) 4. Template method. Save any sound file (WAV format) obtained by the above three methods as a template file. When recording is needed, open the template file. If the time is still insufficient, it can be extended according to the second and third methods mentioned above. You can start recording. The advantage of this method is that it occupies less memory and avoids the phenomenon of "insufficient memory". Second, make WAV sound files easy to "slim down". Wav format audio files are huge, and we can use the tools that come with the "recorder" to compress them. 1. Save as transformation. Open the WAV file to be compressed, and click File → Save As. In the Save As dialog box that appears, click the Change button below to open the Sound Selection dialog box, select MPEG Layer-3 as the format, and then click OK to return to the Save As dialog box. In the file name box, type a file name with an MP3 extension, and click Save to compress it into a much smaller MP3 format (about 1/6 of the original file), even if it is played on an MP3 player (as shown in Figure 3). (Figure 3) 2. Direct conversion. After the recording, don't save it. Open the file menu of the burner, click Properties to open the voice properties dialog box, click Convert Now to open the voice selection dialog box, select MPEG Layer-3 as the format, and click OK → OK continuously to complete the format conversion. Note that when saving, just change the file extension to MP3 (as shown in Figure 4). There is no map here. Please visit my blog: /joming/
