SID chip measurements
- input: sweep.wav - 10 seconds long logarithmic sweep from 20 Hz to 20 kHz, with 2 s silence before and after, sample rate 48 kHz
- file names: cutoff-resonance.wav or bypass-volume.wav, filter mode according to parent folder name
The measure.bas program in the A-SID repo was used to setup the filter and the audio I/O was taken from the A/V port using the DIY breakout connector described here.
Performed on C64C, ser. no. HB41416598E, made in Hong Kong.
Files in bp-res are separated from the rest as they are from a following measurement session and I didn't match volumes with the previous ones.
TBD
IRs can be extracted using the getIR.m GNU Octave script in the A-SID repo.
