this is a parameter used when booting supercollider (-z
). it specifies the number of audio samples calculated in each computation cycle. the default value is 64. lower values give lower latency at the expense of higher CPU load.
when using control rate signals, the audio block size specifies the rate at which control signals are calculated: one control sample is calculated for each audio block, hence for audio block size 64 and server running at 44.1 kHz, the control rate is 44100/64 = approx. 689 Hertz. decreasing the audio block size increases the control rate.
