Encoding speed depends on the processor available to this tab during this ALAC-to-FLAC job.
Available memory can limit very large ALAC conversion jobs.
Check picture, sound, and timing in FLAC before removing the source.

FLAC serves music archives, mastering, and lossless playback, whereas ALAC commonly serves Apple Music libraries and lossless archives.
For ALAC-to-FLAC delivery, plan for larger files than lossy formats.
After leaving ALAC, the receiving app must support the streams encoded inside FLAC, not only its extension.

ALAC to FLAC taking too long? Check available memory; long, high-resolution sources need substantially more.
FLAC converted from ALAC not opening? Test a compatible player and inspect the output streams.
Use the receiving app’s documented FLAC profile when generic playback succeeds but import fails.

When does ALAC to FLAC conversion make sense?

It is useful when ALAC media created for Apple lossless storage must enter a FLAC system designed for lossless distribution.

Where is the ALAC source processed?

The browser prepares FLAC from ALAC on this device instead of sending the source to a remote conversion server.

How can I approve FLAC converted from ALAC?

Test the FLAC file in the receiving app and compare duration, channels and loudness with the ALAC source.
