WebIf you think about it, this is exactly the same process as when you send audio out through your interface’s D-A converter and back through its A-D converter. The D-A converter reconstructs the analogue waveform, and the A-D re-digitises it, via the appropriate anti-aliasing filter, at the new sample rate. If your A-D has a 16-bit mode you ... WebIf you want it to be fully general and reusable, just take a function argument and yield function (last, number), and replace None with sentinel = object ().
