Output format: mp3

WAV is what a field recorder, an interview rig or a DAW export hands you, and it is enormous: about ten megabytes per minute in stereo, which is why the file bounces off mail limits and podcast uploaders. An MP3 at 192 kbps carries the same session at roughly a tenth of that weight. The encode runs on this device, which counts for something when the recording is a confidential interview.

Frequently asked questions

How much smaller is the MP3 than the WAV?
Around one tenth, for a standard CD quality source. An hour of interview drops from roughly 600 megabytes to something you can attach to an email.
Is MP3 good enough for a podcast or a lecture?
Comfortably. Spoken word is the easiest job an MP3 encoder is ever handed, and 192 kbps sits far above what the format needs for a voice.
Should I edit before or after converting?
Edit first, while the audio is still WAV, and convert at the very end. Every export to MP3 is a fresh lossy encode, so you want exactly one of them in the chain.
