When to Use MP3 vs WAV
- MP3 — Compressed format ideal for web playback, podcasts, music streaming, and mobile apps. Smaller file size at the cost of some audio data.
- WAV — Uncompressed lossless format preferred for audio editing, broadcast, and archiving where quality must be preserved.
Bitrate Options
For MP3 output, choose from 128k (compact), 192k (balanced, default), or 320k (high quality). Higher bitrates produce better audio but larger files.
