"BISCUIT style" bit crushing

Howdy,

I just was curious about how that bit-wise muting of the BISCUIT hardware fx would sound in an own implementation. OSM attached, don't expect too much, it's currently only the muting and no other fx of the original.

peace, bootsy

Like that 😀 - adds a s***load of harmonics real quick, even to a sine. Here's the same algorithm to assembly (optimises really well with ASMs integer stuff) and normalised the output so it doesn't go quiet when you mask the upper bits...

P.S. See you're getting some nice plaudits in Sound on Sound again - Ferric featured in the Mix Rescue article this month.

Ahh integer assembler vodoo 🙂 I did not even knew that this is supported in the asm module. Why not in the code box too? Anyway, your code looks really pristine.

Only for bitwise logic kinda stuff - you can't do maths with them coz sse thinks they're really floats (hmm, now there's an idea for some really nasty distortion). As for the code, thanks for the compliment - a perfect example of the excellent free tuition available from the forum's coding gurus rather than any innate genius on my part!

BTW - Great blog you have there - genuinely useful plugins, techy talk, pychoacoustics etc... makes a nice change from the usual 'clones plus hyperbole' formula that permeates so much of plugin land.

It's interesting, but hard to figure out in what kind of plug it could go.

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
