Sample-rate/bit-depth reducer algorithm?

How do I create such things in Synthmaker? I can imagine one way to do sample rate reduction would be to clock a S/H (with audio source as the input) by the desired output sample rate, but how do I reduce the bit-depth?

Oh, neat. 🙂

I am not really a coder though, so except for stefan's "fucked up" version which had a good explanation of what the code does, I can't figure out what is happening quite so well. 😊

I appreciate the link, but I think my original question, which is how to do such a thing, remains unanswered.

Get my latest module pack and check out the bitcrusher in the effects section. This is _very_ rudimentary and does alias a lot but might give you an idea what to look for.

I think he's looking to reduce the actual bits/samplerate for a file/output. e.g. Load a 24bit/96kHz sample, then "Save As..." 16bits/44.1kHz. Or if the host is running 16bits, SM processes as 24bits.

Right uvacom? BTW, welcome to the forums.

Thanks, infuzion - I'm happy to be at this forum, I'm really suprised how active the community is even in this early stage of SynthMaker's (hopefully very long) product life.

Actually, sk0re has what I wanted - I was looking for a realtime effect like a bitcrusher/decimator.

More important to me is the understanding of how such a thing would work inside synthmaker. A module that does it is nice, but if I just use somebody else's module the underlying concept remains a mystery to me. Of course, I'm not interested in reinventing the wheel either, but for my purpose I need a solid understanding of sample-rate/bit-depth reduction.

Oh, and thank you sk0re!

It is already clear that you will be a tremendous asset to the SM community.

(s?)he is; the module-mega pack alone is a huge help.

O_o thanks for the flowers. And yes, I am male 😉

    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.
