File Conversion Guides
Learn about bitrate, channels, audio quality, and practical conversion choices.
Choosing an MP3 bitrate
128 kbps is often enough for speech and podcasts. 192 kbps is a balanced choice for most audio.
Mono or stereo
Choose mono for speech when file size matters and stereo for music or audio that already has two channels.
Check the source
Higher bitrate cannot repair a distorted or repeatedly compressed source.
