About this option

Speech doesn't need the bandwidth that music does, which is why many podcasts publish at 64 kbps mono. This page opens the compressor on exactly that: small files, quick downloads, and voices that stay clear.

Frequently asked questions

Is 64 kbps good enough?

For mono speech, yes. Podcasts with music or sound design sound better at 96–128 kbps stereo.

How big is an hour at 64 kbps?

About 29 MB.

Can I remove background noise first?

You can, using the Audio De-Echo tool, then compress the cleaned file.
