On-device encoding can work the processor harder than ordinary playback during this AAC-to-PCM job.
Large AAC inputs may take several minutes on older hardware.
Review the beginning and end of PCM after the download finishes.

PCM serves audio engineering, interchange, and analysis, whereas AAC commonly serves streaming, mobile playback, and compact delivery.
For AAC-to-PCM delivery, plan for missing container metadata in raw files.
After leaving AAC, the receiving app must support the streams encoded inside PCM, not only its extension.

AAC to PCM taking too long? Try a small source first to separate a performance issue from a format issue.
PCM converted from AAC not opening? Test a compatible player and inspect the output streams.
Check whether the receiver supports this PCM variant: missing container metadata in raw files.

When does AAC to PCM conversion make sense?

It is useful when AAC media created for efficient distribution must enter a PCM system designed for uncompressed sample data.

Where is the AAC source processed?

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

How can I approve PCM converted from AAC?

Test the PCM file in the receiving app and compare duration, channels and loudness with the AAC source.
