Bedroom Producers Blog has released BPB Dirty Spring, a freeware spring reverb effect in VST2, VST3, AU, and AAX plugin formats for digital audio workstations on Windows and macOS. This is what they have to say about it...
BPB Dirty Spring is a free spring reverb VST plugin with a built-in bitcrusher.
BPB Dirty Spring is a simple plugin designed to sound good out-of-the-box. It's easy to use, too. Adjust the Decay and Tone knobs to get the desired spring reverb character. You can preview it by pushing the Kick button (it simulates kicking/hitting a hardware spring delay).
The Pre knob adjusts the pre-delay time, which can be used to achieve some interesting echo/delay effects. I showed all of this briefly in the quick video demo that you can watch below.
BPB Dirty Spring's "secret sauce" is the built-in bitcrusher. Placing a bitcrusher on reverb isn't everyone's cup of tea, so the feature is completely bypassed by default. However, I love crunchy-sounding spring reverbs, and I highly recommend giving this feature a try.
There are several bitcrushing modes to choose from, ranging from very subtle to over-the-top. Try using some of these on sampled drums to get that classic 8-bit sampler effect.
Use a short Decay setting and adjust the Mix knob so that the bitcrushed signal is just a subtle lo-fi layer. Or, crank up the Decay and enjoy the sound of an extremely lo-fi spring reverb.
