Local conversion competes with other open apps for processor time during this PCM-to-AAC job.
Long PCM files consume more memory and take longer to decode.
Compare the AAC duration with the source before publishing.

AAC serves streaming, mobile playback, and compact delivery, whereas PCM commonly serves audio engineering, interchange, and analysis.
For PCM-to-AAC delivery, plan for quality loss when repeatedly re-encoded.
After leaving PCM, the receiving app must support the streams encoded inside AAC, not only its extension.

PCM to AAC taking too long? Free local memory and keep the conversion tab in the foreground.
AAC converted from PCM not opening? Test a compatible player and inspect the output streams.
If AAC is rejected, compare its codec and stream settings with the destination specification.

When does PCM to AAC conversion make sense?

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

Where is the PCM source processed?

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

How can I approve AAC converted from PCM?

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