The device processor performs decoding and encoding during the job during this ALAC-to-M4A job.
Long ALAC files consume more memory and take longer to decode.
Keep the source until the M4A result passes a full playback check.

M4A serves Apple devices, podcasts, and compact music files, whereas ALAC commonly serves Apple Music libraries and lossless archives.
For ALAC-to-M4A delivery, plan for codec differences hidden by the extension.
After leaving ALAC, the receiving app must support the streams encoded inside M4A, not only its extension.

ALAC to M4A taking too long? Close other demanding apps, then test a short sample before the full file.
M4A converted from ALAC not opening? Test a compatible player and inspect the output streams.
A M4A extension alone may not be enough; verify the required internal codec.

When does ALAC to M4A conversion make sense?

It is useful when ALAC media created for Apple lossless storage must enter a M4A system designed for everyday audio delivery.

Where is the ALAC source processed?

The browser prepares M4A from ALAC on this device instead of sending the source to a remote conversion server.

How can I approve M4A converted from ALAC?

Test the M4A file in the receiving app and compare duration, channels and loudness with the ALAC source.
