About MP4 to AIFF Conversion
MP4 to AIFF conversion extracts audio from an MPEG-4 video and encodes it as an uncompressed Audio Interchange File Format file. AIFF was developed by Apple in 1988 based on the IFF standard and stores audio as raw PCM data — no compression, no quality loss. It is the Mac equivalent of WAV and remains the preferred format for professional audio on Apple platforms.
Our converter decodes the audio stream from your MP4 file and writes it as 16-bit or 24-bit PCM samples in the AIFF container. This produces studio-quality audio suitable for editing, mastering, and archival purposes.
Why Convert MP4 to AIFF?
AIFF is the format of choice when you need uncompressed audio from video footage and you work on Apple hardware. Logic Pro, GarageBand, and Pro Tools on Mac all handle AIFF natively with full metadata support. Unlike lossy formats, AIFF preserves every sample from the decoded audio stream, giving you the highest possible fidelity to work with in a DAW. Archivists choose AIFF for long-term preservation because it contains no compression algorithms that could become obsolete.
