I'd be thinking you could compose your ms based picture on the sample
data. For instance, if you sample on cpu-clock at 100kHz, then a 100
samples get you a full blue slice, 50 get you a 50% blue slice, etc.

Of course, since its sample based, you can miss some detail, but I think
you're looking at the large picture anyway.

Would this work?
