128 kbps is good for general listening and podcasts. 192-256 kbps is near-CD quality. 64 kbps works for voice-only recordings.
Input supports MP3, WAV, FLAC, AAC, OGG, and more. Output is typically MP3 for maximum compatibility.
Depending on the source, compression can reduce file size by 50-90%. WAV to MP3 conversion alone typically achieves 80-90% reduction.
