Supported audio formats

Piezo has native support for recording in two of the most popular compressed audio formats: MP3 and AAC.

MP3

MP3 is the most popular format for audio compression, making it the most universal file type; MP3 files can be played almost anywhere. Because MP3 files are compressed lossily, some audio quality may be lost when they're created. However, the files are also very compact, using only a small amount of disk space.

The Variable Bit Rate (VBR) option for MP3 files allows the software to dynamically adjust the bitrate of the encoding, saving disk space without any additional quality loss. Modern MP3 encoding is largely done with VBR.

AAC

Though not as universal as MP3, AAC is another well-known format for audio compression. AAC files play well on devices made by Apple, including the Mac and iOS devices. Like MP3, AAC files are compressed lossily, meaning some audio quality may be lost when they're created. AAC files are generally even more compact than MP3, using less disk space for the same level of quality.
