Encoding speed depends on the processor available to this tab during this MKA-to-AU job.
Long MKA files consume more memory and take longer to decode.
Confirm the AU output meets the receiving system’s technical limits.

AU serves Unix workstations and older audio software, whereas MKA commonly serves multi-track audio archives and flexible containers.
For MKA-to-AU delivery, plan for limited modern consumer support.
After leaving MKA, the receiving app must support the streams encoded inside AU, not only its extension.

MKA to AU taking too long? Close other demanding apps, then test a short sample before the full file.
AU converted from MKA not opening? Test a compatible player and inspect the output streams.
Inspect the generated streams when an app recognizes AU but refuses playback.

When does MKA to AU conversion make sense?

It is useful when MKA media created for advanced audio storage must enter a AU system designed for legacy workstation exchange.

Where is the MKA source processed?

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

How can I approve AU converted from MKA?

Test the AU file in the receiving app and compare duration, channels and loudness with the MKA source.
