SP950 filter #7300

Closed RainbowShatter closed 4 months ago

RainbowShatter commented 4 months ago

Enhancement Summary

i think the idea of having a plugin that has a similar sound to what the sp950 filter does, it would make it get a little more of attraction, since i came from ableton live and i used a lot of this plugin for some projects, but is there any for LMMS?

Implementation Details / Mockup

it should appear in the same place the normal equalizer and low pass filter are, in the effects chain as an option plugin

This is the sp950 filter in question. Looks like some sort of a 90s drum machine type filter (used in boom bap beats) or for lofi beats. We do have the VyNill ladspa plugin which is similar but is very buggy to start with.

I believe a simple hi pass filter is enough to emulate this. ~Will close once the OP gets back~

Asked this question to lost on discord and found out that bitcrusher is what @RainbowShatter has been looking for.

Well, if it's the dac grit of the 80's samplers we're after it's the A-law/u-law compressors you want. It's in the SWH Lv2 suite.

The SP950 plugin's central slider is similar (or perhaps identical) to the sample rate knob ("FREQ") in LMMS's native Bitcrush effect. The filter knob is a butterworth lowpass (with a 36 dB slope), identical to almost all lowpass filters built into LMMS (except it claims to be "analog", but in practice this is usually a meaningless term unless it has some nonlinearities thrown in). Some arbitrary perfectly-linear filtering is applied before and after that main processing to match it with the hardware it's emulating.

TL;DR @RainbowShatter Set up your signal chain as Equalizer -> Bitcrush -> Equalizer and you'll be able to create sounds effectively identical to everything the plugin's capable of, but with a lot more versatility.
