We once did a MathWorks internal hackathon submisison to transmit radio signal over a ThingSpeak channel. We encoded the audio signal and spread the base64 encoded data over all 8 fields and the status field, then decoded it on the other side. It worked, though you had to be careful about buffereing and the aido quality was not amazing.
I would suggest you calculate the size of the signal, then determine how much you have to downsample it to get it to fit in a single ThingSpeak message, and then decide if the quality will be high enough to proceed. You can use the read data API to get the info back out.
