The next release of Maxwell (in development) - will have the ability to process audio in an x/y plot. However, the output is still vector in nature and not continuous stream audio. So you will be able to view audio / oscilloscope music as output - but you will not be able to create audio streams - as mentioned, Maxwell is designed to communicate with frame-based (vector array) DACs - and not continuous data (audio) DACs.
I would love to support the output to continuous data (audio) DACs sometime in the future. Whether that is within Maxwell or a new application has not been determined yet.
