On-device encoding can work the processor harder than ordinary playback during this MP3-to-AIF job.
Available memory can limit very large MP3 conversion jobs.
Inspect the AIF file in the exact player or editor that will receive it.

AIF serves Apple-oriented editors and sample libraries, whereas MP3 commonly serves phones, websites, podcasts, and universal playback.
For MP3-to-AIF delivery, plan for large uncompressed files.
After leaving MP3, the receiving app must support the streams encoded inside AIF, not only its extension.

MP3 to AIF taking too long? Check available memory; long, high-resolution sources need substantially more.
AIF converted from MP3 not opening? Test a compatible player and inspect the output streams.
Check whether the receiver supports this AIF variant: large uncompressed files.

When does MP3 to AIF conversion make sense?

It is useful when MP3 media created for easy sharing must enter a AIF system designed for lossless editing.

Where is the MP3 source processed?

The browser prepares AIF from MP3 on this device instead of sending the source to a remote conversion server.

How can I approve AIF converted from MP3?

Test the AIF file in the receiving app and compare duration, channels and loudness with the MP3 source.
