M4A to WAV

This lesson is part of Web Developer Tools · All levels

Summary

M4A to WAV converts the M4A file that usually contains AAC audio to WAV PCM. M4A is popular with iTunes and Apple devices because of its efficient size, while WAV is easier to use for editing and is compatible with many applications. The conversion decodes AAC and then writes a PCM sample, so the file size increases. The quality of the results remains the same as the original M4A.

Key points

M4A generally contains AAC audio inside the MP4 container
WAV PCM stores audio without lossy compression
The AAC decode produces a much larger sample of PCM.
Metadata like the title and the artist doesn't necessarily have to be carried to the WAV.
Use WAV when the editing app does not support M4A
