What happens when you compress audio files?
Digital audio files are usually compressed, using computer programs. This makes the file smaller. There are three varieties of audio file compression; each offers certain advantages:
- Lossless audio files – they offer the highest-quality sound, but they also result in the largest file sizes. The two most popular formats of lossless audio files are WAV (Waveform Audio Format) and AIFF (Audio Interchange File Format).
- Compressed lossless audio files – they squeeze audio data into a smaller file size. The two most popular formats of compressed lossless audio files are FLAC (Free Lossless Audio Codec) and Apple Lossless.
- Compressed lossy audio files – they remove certain types of audio data to shrink the file size. The most common compressed lossy audio formats are AAC (Advanced Audio Coding) AAC and MP3.
