Question 1

What is an M4A file?

Accepted Answer

M4A is an audio file stored in an MPEG-4 container. It commonly contains AAC or ALAC audio. This player accepts both.m4a and.m4b files, but playback depends on whether your browser supports the audio format inside the file.

Question 2

Is my M4A file uploaded?

Accepted Answer

No. Your file is played locally in your browser and is never sent to our server. The temporary browser reference to your file is removed when you replace the file, remove it, or leave the page.

Question 3

Why won’t my M4A file play?

Accepted Answer

Files with the.m4a extension can contain different audio formats, and your browser may not support the format used by a particular file. This player will show an error if the file cannot be loaded or played. If that happens, try a different browser or convert the file to another audio format.

Question 4

Can I change the playback speed or loop the audio?

Accepted Answer

Yes. After selecting a file, you can play or pause it, move to a different position, loop it, adjust the volume, and choose a playback speed from 0.5× to 2×.
