About this conversion
What happens
After consent, strict FLAC input converts offline with its admitted mono/stereo rate and layout preserved; metadata is removed and independent fast-start M4A validation gates publication.
Limits
250 MiB input. 15 minutes, up to 0×0, and 100 MiB output.
Things to know
The output uses a fixed 128 kbit/s target. AAC is smaller and more portable, but it cannot preserve every detail in the FLAC source. Malformed FLAC, extra streams, unsupported rates or layouts, excessive duration, timeout, or invalid AAC/M4A output fail closed.
