Is it possible to upsample live input and have it playback at the upsampled rate with a few delay lines? (in: DSP and Plugin Devel…)

As long as the two samplerates aren’t derived from the same clock source, they are always going to drift apart, so you need an asynchronous SRC. Take a fractional interpolator and some kind of control loop to continuously steer the input-output latency to some target value. Basically, if latency (the distance between read and write pointers) grows beyond the target value, increase the output samplerate slightly, and the other way around if latency goes lower, decrease it. How low you can go with…
