Frequently Asked Questions

Which M4A files can I use?

Upload an unprotected M4A audio recording, including AAC or Apple Lossless audio that the server can decode. Album artwork is ignored during conversion.

How do I convert a voice memo?

Save the memo as an M4A file, choose it in the uploader, leave the start time at zero and choose a bitrate. For a memo longer than five minutes, set the length of the excerpt to export.

What bitrate should I choose?

Try 96 kbps for speech or the default 192 kbps for music. A higher bitrate can preserve more detail during encoding and produces a larger file.

How long can my recording be?

The default upload limit is 100 MiB. Recordings may be up to 30 minutes long, and each export can contain up to five minutes of audio.

What happens to other tracks and tags?

The MP3 contains the first audio track. Embedded artwork, chapters and source metadata are omitted.
