FLAC to AIFF: the timed-stream transcoding route explained
Converter.now decodes the waveform and channel layout carried by FLAC, then writes the codec and container profile used for AIFF. Duration can remain identical while compression, channel mapping, frame cadence, metadata, or auxiliary streams change. FLAC frames decode to lossless samples, but the stream can still carry unusual channel assignments, sample rates, cuesheets, and Vorbis-comment metadata. AIFF delivery stores waveform samples in an interchange-oriented chunk structure, commonly using big-endian PCM with explicit precision, rate, and channels.
Decoded media - Losslessly compressed audio that preserves decoded samples and supports rich tags. Encoded delivery profile - Apple's chunk-based Audio Interchange File Format commonly carrying big-endian PCM samples.

Reading FLAC correctly and satisfying what AIFF expects
What can fail when Free Lossless Audio Codec is interpreted
FLAC does not make a lossy source lossless again, and some basic players reject less common sample rates or channel layouts.
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.
Acceptance evidence for the converted AIFF
Record the FLAC evidence before conversion
Compare duration, sample rate, channels, peak levels, and tags with the decoded source.
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 FLAC to AIFF
Switch to AIFF only once the destination player, editor, or service has confirmed support for its exact container and codecs. If extra tracks or the original encoding must survive, FLAC remains the safer choice.
What changes between the FLAC model and the AIFF deliverable
- The source stores losslessly compressed audio that preserves decoded samples and supports rich tags; the destination stores Apple's chunk-based Audio Interchange File Format commonly carrying big-endian PCM samples. Compare application metadata after that structural change.
- Metadata handling differs between FLAC and AIFF; do not assume every application-specific field carries across untouched.
