About the WAV to M4A Converter
M4A with the AAC codec is Apple's standard lossy format. At the same bitrate AAC usually sounds a little better than MP3, and it is the native format for iPhone, iTunes and Apple Music.
A 4-minute WAV of about 40 MB becomes roughly 7.5 MB as 256 kbps AAC. If you need lossless M4A instead, choose ALAC in the converter.

Frequently asked questions
Is M4A the same as AAC?
M4A is the file container and AAC is the codec inside it. M4A files can also hold lossless ALAC audio.
Is AAC better than MP3?
At low and medium bitrates AAC generally sounds better than MP3. At 256 kbps and above both are close to transparent for most listeners.
