The device processor performs decoding and encoding during the job during this PCM-to-AIFF job.
Long PCM files consume more memory and take longer to decode.
Compare the AIFF duration with the source before publishing.

AIFF serves DAWs, mastering tools, and Apple workflows, whereas PCM commonly serves audio engineering, interchange, and analysis.
For PCM-to-AIFF delivery, plan for large files compared with compressed audio.
After leaving PCM, the receiving app must support the streams encoded inside AIFF, not only its extension.

PCM to AIFF taking too long? Close other demanding apps, then test a short sample before the full file.
AIFF converted from PCM not opening? Test a compatible player and inspect the output streams.
If AIFF is rejected, compare its codec and stream settings with the destination specification.

When does PCM to AIFF conversion make sense?

It is useful when PCM media created for uncompressed sample data must enter a AIFF system designed for lossless production.

Where is the PCM source processed?

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

How can I approve AIFF converted from PCM?

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