Here&#8217;s what they have to say about it:<\/p>\n<p style=\"padding-left: 40px;\">&#8220;Bitcrust\u2019s DSP is written from scratch in C++, against public datasheets and general DSP literature. The 6581 \/ 8580 architecture is the starting point, not the destination: oscillators, envelope, filter, and the glue between them are designed to capture the SID\u2019s character \u2014 the bit-crushing, the leaky integrators, the resonant bite \u2014 without trying to be a bit-accurate or cycle-accurate emulation.<\/p>\n<p style=\"padding-left: 40px;\">Where the silicon is interesting, we lean in.
