Quick Links



Screenshot Plugin Description
amp_sim Amp Sim Guitar and bass amplifier with up to 16x oversampling, mono/stereo routings, pre/post/triggered noise gate, booster pedal function, interactive inter-stage EQ bands, dynamic Depth and Presence bands, and maximizer.
bass_squeezer Bass Squeezer Split-band compression and filtered distortion for that instant bathtub bass sound.
bus_comp Bus Comp Submix bus oriented compressor with automatic/program-dependent release, fadeable stereo linking, Mid/Side mode, external sidechain input with high pass filter, instability noise, dynamic saturation, optional output hard clipping and dry/wet mix for parallel compression.
cab_sim Cabinet Sim Simple cab sim with 5 burnt-in impulse responses, 4 for guitar and 1 for bass. Can not load IRs from file.
chug_thug Chug Thug Simplified split-band processor to tame the low end of distorted guitars when palm muting.
consolidator Consolidator A set of 3 compressors with sidechain filter and stereo linking chained in a row, each with its own character. Has a dry/wet mix parameter for instant parallel/NY compression and Mid/Side mode.
correlation_meter Correlation Meter Inspect your song's stereo phase balance and find mono-problematic areas by watching an indicator go red.
No UI DC Filter Multi-channel capable and extremely narrow DC offset removal filter.
dc_offset DC Offset Adds constant 0 Hz content to all channels of a signal and shifts waveforms up or down, probably only useful to test DC filters.
eq_560 EQ 560 Classic American 10-band graphic console equalizer. Limited flexibility, fast and streamlined workflow. Uses 2x oversampling for accurate high frequency filter curves, adds some character.
filthy_delay Filthy Delay Stereo delay with multiple routings (currently: stereo, inverted, ping-pong, mono), plus optional filters, boostable saturation and downsampling degradation in the feedback path.
foldback_distortion Foldback Distortion Folds waves between 0 and an adjustable ceiling, very harsh and nasty distortion.
gate_expander Gate/Expander Several channel routings, external sidechain, sidechain filter, fadeable stereo linking, hysteresis, and it can be switched between gate (fades to silence) and expander (fades to defined volume) modes.
hard_clipper Hard Clipper Simple and effective, chops away peaks above an adjustable ceiling volume, call it cold transistor distortion if you must.
impulse_generator Impulse Generator Generates a 1-sample impulse when triggered, for use when sampling devices to IRs.
interpolated_noise Interpolated Noise Various flavours of pleasingly natural and organically chaotic noise created with the help of various interpolation methods.
knee_clipper Knee Clipper A clipper neither purely hard nor purely soft, and yet a unification of both.
mic_combiner Mic Combiner Utility to facilitate the process of merging two mono microphone signals into one. Processes each microphone signal individually, allows to set a balance/mix between both microphones, and sums them to mono. Can adjust timing between signals.
m-s_fader M-S Fader Converts a stereo source to a Mid/Side signal and then fades between 100% Mid and 100% Side signal, or a mix of both. Great to remove the center signal, or to focus in on it.
phase_scope Phase Scope Visualizes the stereo field of a signal, also commonly known as Goniometer, Vector Scope or Lissajous. Selectable visualization colour and optional freeze-on-pause function.
reference_noise Reference Noise Provides various noise profiles, filtered or plain, to use as target reference for spectral/visual mixing.
ring_mod Ring Mod Multiplies the input signal with a carrier signal, which can lead to all sorts of warbly modulation and distortion effects.
signal_crusher Signal Crusher Sample rate changes, lost sample reconstruction, bit truncation, bit dithering... it's all in here.
sine_clipper Sine Clipper A clipper that uses the smoothness of the sine wave to tame loud signal peaks.
soft_clipper Soft Clipper Increasingly lowers signal peaks the closer they get to an adjustable ceiling volume, call it warm tube overdrive if you must. Has up to 16x oversampling, DC blocker and optional final (non oversampled) hard clipping stage for true 0 dBfs output.
stereo_bleed_remover Stereo Bleed Remover An attempt at removing unwanted bleed between channels in a stereo signal.
stereo_checker Stereo Checker Displays the inter-channel relation of a two-channel input signal.
stereo_pan Stereo Pan Utility that implements various standardized pan laws, as well as some custom methods by me.
telephone Telephone Makes vocals sound like they're coming through a phone receiver, also worth slamming on drums.
test_signals Test Signals A collection of 13 different test tone and noise generators in one plugin, 14 if you count silence. Can have a different generator on each channel, can output both or just one channel, can sum both channels.
track_comp Track Comp A low-CPU and ultra-flexible compressor, with everything from peak/RMS detection over feed-forward/-back modes, stereo linking and channel setups to automatic gain compensation and dynamic saturation.
volume_range_trim Volume Range Trim Fader to non-destructively alter a signal's volume within a specific range (+/- 6, 12, 24, 48 dB), gives finer control when automating volume. Auto-adapts to track's channel count.
volume_trim Volume Trim Simple fader to alter a signal's volume, useful for gain-staging between plugins. Auto-adapts to track's channel count.
wave_scope Wave Scope Waveform display that can visualize various mono/stereo channel streams as Decibels, signed or absolute samples. With fadeable colours and freeze-on-pause function.

(There may be more in the future)



This is just a fun project for me, I do this on the side to waste time or template C++ code, so don't expect too much of an effort. But if you find any bugs, or if you have any suggestions for improvements, feel free to report them in the issue tracker, I'll have a look there every now and then.

Have fun! <3
