How to Compress Music Files

by Nina Nixon

Since you can compact as much as 20 megabytes (MB) into 1 MB of space in some cases, compressing music files can be a major computer space saver. If you plan on expanding your lyrical library, you benefit from compacting these file types. Consider implementing compression on a regular basis. Then, when you are ready to download a new track, you won't have to ask yourself if there is enough disk space--because you'll already know.

Step 1

Right-click on the music file. (Compatible audio formats include .asx, .wm, .wma, .wmx, .wav, .mp3, .m3u, and aac.)

Step 2

Select "Properties," go to the General tab, and then click "Advanced."

Step 3

Check "Compress contents to save disk space" and then click "OK."

Click "Apply" and then click "OK."


  • Find the bit rate and sample rate of any music file by clicking on the "Summary" tab. It is accessible from the audio file's "Properties" dialog box. These rates do not change after you apply compression.


  • Some codecs (music compression software) interpret file formats differently; therefore, not all music files adapt well to compression. Open a file after the process has completed and make sure the music sounds clear to your ears.
