Frequently asked questions

Is M4A the same as AAC?

M4A is a container that usually holds AAC audio. Both are accepted; the output is converted to MP3.

Does converting reduce quality?

Going from one lossy format to another loses a little. At 192 kbps the difference is hard to hear for speech and most music.

Can I convert several memos?

Convert them one after another; each file is processed locally.
