AVI to AIFF: the audio-stream extraction route explained
Converter.now selects the audio stream in AVI, leaves the picture stream out, and encodes that sound as AIFF. The result is audio, not a silent copy of the video. AVI is reconstructed from RIFF indexes and interleaved chunks; codec tags, frame timing, keyframes, and audio alignment determine whether seeking remains stable. AIFF delivery stores waveform samples in an interchange-oriented chunk structure, commonly using big-endian PCM with explicit precision, rate, and channels.
Decoded from an older Microsoft media container commonly paired here with Xvid video and MP3 audio. Encoded to Apple's chunk-based Audio Interchange File Format commonly carrying big-endian PCM samples.

AVI source facts versus AIFF output requirements
What can fail when AVI video container is interpreted
AVI has limited support for modern metadata, captions, variable frame rates, and some web players.
What AIFF audio format cannot safely promise
AIFF files can be large, and tags, loop points, or uncommon sample precision are not handled uniformly.
How the AIFF writer handles this route
Apple's chunk-based Audio Interchange File Format commonly carrying big-endian PCM samples is what gets written, labeled as audio/aiff. Whether that actually opens depends on the receiving application, not on the file extension.
How to confirm the converted AIFF actually works
Record the AVI evidence before conversion
Test seeking and audio sync in the target player, not only the opening frame.
Test the AIFF file in its receiving workflow
Compare sample rate, bit depth, channels, duration, peaks, tags, and loop markers in the target audio editor.
When to actually choose AVI to AIFF
Choose this route to deliver dialogue, music, or a soundtrack to a system that accepts AIFF; keep AVI when its pictures, captions, or visual timing still matter.
What changes between the AVI model and the AIFF deliverable
- Timed frames possible in AVI cannot remain an animation in AIFF; verify which frame or static rendering was used.
- Metadata handling differs between AVI and AIFF; do not assume every application-specific field carries across untouched.
