The SID Chips visualized & benched

Since the introduction of the original SOASC= there's been many comments, questions, misunderstandings and irritations, possibly even joy about the filter characteristics off the random Commodore 64 SID chips used in recording. Finally, I got the time to do something about it - both visual and audible style of way!


The software I used are made by other people, which are:

SIDBENCH.PRG
and
SIDTESTDISK_4.0C1.d64

Both links for more information about them at bottom of this page.

The SIDBENCH.PRG was created to rule out bad chips, remarked ones and possibly fake ones. So, to make it official: SOASC= only use real C64 sid chips sitting inside self-bought machines by me from used shops, friends, fleemarkets or cheap defective (then repaired by me) from online auction-type websites in Norway (during 2007 until present time).

The .D64 image contains a long run 25 minutes, 3 passes recording procedure in order to create a near-match sidplay-residfp type of profile (I believe). The recordings are 48000hz, 16-bit, mono.

For those interrested you can use these recordings to create a emulation profile in order to attempt to emulate the SOASC= sound and filter softwarewise, good luck :-)


The pictures below are taken from the first two SID Chips in recording (R4 and R2), R3 and R5 will follow next year.
