Adapt legacy workstation exchange to a workflow built for advanced audio storage
Supply MKA when an editor, player, or delivery form will not accept AU
Create a MKA copy from AU for multi-track audio archives and flexible containers

The device processor performs decoding and encoding during the job during this AU-to-MKA job.
A short AU sample is quicker to process than a full-length recording.
Check picture, sound, and timing in MKA before removing the source.

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

AU to MKA taking too long? Process a shorter section to determine whether file size is the bottleneck.
MKA converted from AU not opening? Test a compatible player and inspect the output streams.
Use the receiving app’s documented MKA profile when generic playback succeeds but import fails.

When does AU to MKA conversion make sense?

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

Where is the AU source processed?

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

How can I approve MKA converted from AU?

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