AVI to MP3 Conversion Tips
Use Jollycat's trim and crop tools to edit your video before converting. This saves time by only processing the parts you need.
For sharing online, MP3 with H.264 codec provides the best balance of quality and compatibility.
Higher bitrates produce better audio quality but larger files. For music, 256-320 kbps is recommended. For voice recordings, 128 kbps is sufficient.
MP3 uses psychoacoustic modeling to remove frequencies less audible to human hearing. 320 kbps is transparent quality.
