Part 1: About Audio Compression

Audio compression means the unnecessary data is removed from an audio file for size reduction. Generally, audio compression is divided into lossless compression and lossy compression.

Lossless compression (i.e. WAV, APE, FLAC):

Little data is lost after compression when the audios are saved as these formats. But the file size is large. The audio files in these formats take up much storage space.

Lossy compression (i.e. MP3, AAC, OggVorbis, WMA)

The audio files processed with lossy compression take little storage space because the file size is small. The unnecessary data is removed and the critical data is kept well. Therefore, the audio quality is downgraded.

Part 2: How to Reduce Loss of Audio Data?

The data will be reduced after the audio file is compressed. Then, the file size will be small, too. If you want to keep the high audio quality, you shall select lossless compression to keep most of the data.
