Sample Rate (Hardware)

• Distinct from mathematical (DSP) calculation, sample rate also refers to the rate at which samples pass through the flowgraph.

• If there is no rate control, hardware clock or throttling mechanism, the samples will be generated, pass through the flowgraph and be consumed as fast as possible (i.e. the flowgraph will be CPU bound).

• This is desirable if you want to perform some fixed DSP on stored data as quickly as possible (e.g. read from a file, resample and write it back).
