MKV to AIFF: the audio-stream extraction route explained
Only the audio stream inside MKV is pulled out - The picture stream is discarded entirely - And encoded as AIFF. What comes out is genuine audio, never a muted copy of the video. Matroska reading walks segment tracks, codec-private data, clusters, cues, chapters, attachments, and subtitle streams rather than assuming one picture and one soundtrack. AIFF delivery stores waveform samples in an interchange-oriented chunk structure, commonly using big-endian PCM with explicit precision, rate, and channels.
Decoded from a flexible Matroska container capable of multiple audio, video, subtitle, and attachment streams. Encoded to Apple's chunk-based Audio Interchange File Format commonly carrying big-endian PCM samples.

Reading MKV correctly and satisfying what AIFF expects
What can fail when Matroska video is interpreted
A simplified conversion may keep only primary streams, and many browsers do not play MKV directly.
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
The writer builds Apple's chunk-based Audio Interchange File Format commonly carrying big-endian PCM samples and labels the result as audio/aiff. The receiving application - Not the extension alone - Is the final compatibility test.
Acceptance evidence for the converted AIFF
Record the MKV evidence before conversion
Inspect the stream list, subtitles, language labels, chapters, seeking, and sync.
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 MKV to AIFF
Choose this route to deliver dialogue, music, or a soundtrack to a system that accepts AIFF; keep MKV when its pictures, captions, or visual timing still matter.
What changes between the MKV model and the AIFF deliverable
- Timed frames possible in MKV cannot remain an animation in AIFF; verify which frame or static rendering was used.
- MKV and AIFF use different metadata conventions, so application-specific fields should be treated as optional until verified.
