After leaving M4A, the receiving app must support the streams encoded inside DTS, not only its extension.

M4A to DTS taking too long? Try a small source first to separate a performance issue from a format issue.

When does M4A to DTS conversion make sense?

It is useful when M4A media created for everyday audio delivery must enter a DTS system designed for surround-sound delivery.

Where is the M4A source processed?

The browser prepares DTS from M4A on this device instead of sending the source to a remote conversion server.
