Questions

Frequently asked questions

Which format should I use?

MP3 is widely supported, M4A/AAC is efficient, WAV is uncompressed, and OGG suits software that supports open formats.

Does converting improve sound quality?

No. A conversion cannot restore detail already removed from the source. WAV avoids another lossy output but does not add detail.

Is the audio sent to a server?

No. It is read and converted on your device.

Why is the WAV result larger?

WAV stores uncompressed samples, so it is normally much larger than MP3, AAC or OGG.
