Tested output uses FLAC. Current exports do not retain chapters, attachments, or original metadata.
MKA file format guideApple’s extensible audio container stores audio data alongside descriptive chunks. CAF can hold PCM or compressed sound and avoids the classic 4 GB WAV limit.
This workspace still applies its local memory/file limits. Tested output uses 16-bit PCM.
CAF file format guideChoose the sample rate, trim range, and mono or stereo output. Compressed audio formats can discard detail; converting to a lossless format cannot restore sound already lost. Container support depends on the codec inside the file.
