The device processor performs decoding and encoding during the job during this FLAC-to-AAC job.
Available memory can limit very large FLAC conversion jobs.
Check picture, sound, and timing in AAC before removing the source.

AAC serves streaming, mobile playback, and compact delivery, whereas FLAC commonly serves music archives, mastering, and lossless playback.
For FLAC-to-AAC delivery, plan for quality loss when repeatedly re-encoded.
After leaving FLAC, the receiving app must support the streams encoded inside AAC, not only its extension.

FLAC to AAC taking too long? Try a small source first to separate a performance issue from a format issue.
AAC converted from FLAC not opening? Test a compatible player and inspect the output streams.
Use the receiving app’s documented AAC profile when generic playback succeeds but import fails.

When does FLAC to AAC conversion make sense?

It is useful when FLAC media created for lossless distribution must enter a AAC system designed for efficient distribution.

Where is the FLAC source processed?

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

How can I approve AAC converted from FLAC?
