MPEG to AIFF 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, AIFF 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.
AIFF is Apple's equivalent of WAV, storing uncompressed PCM audio with better metadata tagging.
