region of 4116 to 12308 samples. See the section below for information on reducing the
delay.
Oxford SuprEsser LL/LowLatency
This small kernel version has a kernel size of 512 samples.This version gives superior
performance in terms of having a small delay, and thus is more suitable for live de-essing
work at low sample rates, and for the tracking phase of a project, where you are laying
down new tracks from midi instruments, and you don’t want a significant delay between
what you are playing and what you are hearing. The smaller kernel size means the
resolution at low frequencies will be poor, and so cannot be used much below 400Hz.
Depending on your audio buffer size, the delay or latency will be somewhere in the region
of 276 to 3072 samples. See the section below for information on reducing the
delay.
Oxford SuprEsser DS (AAX DSP)
This version has an even smaller kernel size of 128 samples, in order to further reduce the
processing delay. Due to this, the filter range has been reduced to 1 kHz minimum, in
order to prevent poor low frequency performance from producing unexpected
results.
