Compare the ALAC duration with the source before publishing.

ALAC serves Apple Music libraries and lossless archives, whereas MP3 commonly serves phones, websites, podcasts, and universal playback.
For MP3-to-ALAC delivery, plan for weaker support outside Apple ecosystems.
After leaving MP3, the receiving app must support the streams encoded inside ALAC, not only its extension.

ALAC converted from MP3 not opening? Test a compatible player and inspect the output streams.
If ALAC is rejected, compare its codec and stream settings with the destination specification.

When does MP3 to ALAC conversion make sense?
