Overtone GEQ ~ Harmonic Graphic Equalizer


Overtone GEQ is a free 7-band harmonic (overtone) graphic equalizer AudioUnit, AAX, and VST plugin with multi-channel operation support (supporting up to 8 input/output channels, audio host application-dependent).  Overtone GEQ offers extensive internal channel routing capabilities, and supports mid/side channel processing.

Beside equalizing, Overtone GEQ applies harmonic enhancement: it uses 7 harmonic enhancement modules, one for each EQ band.  This generates a complex harmonic coloration you will probably like a lot.

Overtone GEQ was designed to allow audio engineers to apply quick EQ shape adjustments together with adding a bit of harmonic richness to the audio material (mainly mixes and sub-mixes due to a comparably high load this EQ puts on a CPU).

Wigware Ambisonic Decoder (WAD)


Wigware Ambisonic Decoder (WAD)

This program now comes in two flavours, as a Direct Show filter and a VST plugin. The Direct Show Filter allows any Direct Show capable audio player software (such as Windows Media Player) the ability to read and decode B-format wave files (the format of which is specified here on Richard Dobson’s web page – details on the Waveformat extensible file format used can be found on Microsofts web site here – details on Ambisonics can be found here).

The VST version comes in 1st and 2nd order versions (3rd and 4th order versions to follow) and allows you to alter the polar patterns of the speaker feeds either across the whole frequency range or using ‘Shelf Filters’ with a variable cut-off. Both of the VST plugins will derive outputs for a standard ITU 5 speaker array, with higher orders giving better frontal resolution.

PedalBoard ~ Python Audio Library


pedalboard is a Python library for working with audio: reading, writing, rendering, adding effects, and more. It supports most popular audio file formats and a number of common audio effects out of the box, and also allows the use of VST3® and Audio Unit formats for loading third-party software instruments and effects.

Features:

  • Built-in audio I/O utilities (pedalboard.io)
    • Support for reading and writing AIFF, FLAC, MP3, OGG, and WAV files on all platforms with no dependencies
    • Additional support for reading AAC, AC3, WMA, and other formats depending on platform
    • Support for on-the-fly resampling of audio files and streams with O(1) memory usage
    • Live audio effects via AudioStream
  • Built-in support for a number of basic audio transformations, including:
    • Guitar-style effects: ChorusDistortionPhaserClipping
    • Loudness and dynamic range effects: CompressorGainLimiter
    • Equalizers and filters: HighpassFilterLadderFilterLowpassFilter
    • Spatial effects: ConvolutionDelayReverb
    • Pitch effects: PitchShift
    • Lossy compression: GSMFullRateCompressorMP3Compressor
    • Quality reduction: ResampleBitcrush
  • Supports VST3® instrument and effect plugins on macOS, Windows, and Linux (pedalboard.load_plugin)
  • Supports instrument and effect Audio Units on macOS
  • Strong thread-safety, memory usage, and speed guarantees
    • Releases Python’s Global Interpreter Lock (GIL) to allow use of multiple CPU cores
      • No need to use multiprocessing!
    • Even when only using one thread:
      • Processes audio up to 300x faster than pySoX for single transforms, and 2-5x faster than SoxBindings (via iCorv)
      • Reads audio files up to 4x faster than librosa.load (in many cases)
  • Tested compatibility with TensorFlow – can be used in tf.data pipelines!

BlackDiamond ~ Fruityloops Studio Clone


Fruityloops clone with sound samples using Fmodex lib

BlackDiamond (formerly Crazy Machine) is a project I neglected for years until I got back into making music. The package comes with free VST plugins and samples, and soon to be introduced at some point in time, perfect sequencer sample mixer playback thingamagiggy we are now back in full armor trying to create the wildest dreams of software working on BlackDiamond.

Features:

  • Six built in effects for each 16 channels Flange, Chorus, Compression, Echo, Distortion, Reverb
  • fruity loops style pattern manipulation
  • Written in FreeBasic, the most best freeware IDE compiler for basic language
  • Recent May 2019 re-programming to V3
  • VST and Dialog window support, switch plugins with a click
  • calculations are now down to the clock cycle to milliseconds
  • Load VST plugins, samples during playback.
  • View VST plugin dialog, which works when using SET MS method
  • SET MS (Alter VST plugin data) now very easily tuneable
  • Supports ASIO Interface and Microsoft Windows wave file writing

Drops ~ Single Sample Player


Drops is a single audio file sample player plugin in lv2 and vst format for linux.

Load an audio file, play it, loop it, pitch shift it, and make it into something entirely new.

Bitter ~ Bitscope & Intersample Clip Monitor


Bitter shows how many of the available bits are being used by the audio signal, reports clipping samples, and estimates when digital-to-analog conversion would cause inter-sample clips. Typical uses for a bitscope include: verifying that a render dither is working properly; verifying that a particular plugin is not reducing the signal bit depth; testing for faulty audio source data.

Features:

  • Check for Intersample Clipping that may appear during digital-to-analog conversion
  • Detailed display of the usage density of each bit
  • Reveal the bitrate of the digital signal, which may well differ from that of the file’s bitrate or your DAW’s audio engine bitrate
  • Display the audio sample rate

THD Meter ~ Measure Total Harmonic Distortion


MathAudio THD Meter VST/AU

  • Measures Total Harmonic Distortion (THD) in sound cards, speakers and headphones.
  • Applies matched filters for maximizing the signal-to-noise ratio (SNR) in the presence of additive stochastic noise.
  • Supports microphone calibration files.
  • Supports full range of sample rates from 44.056 kHz up to 384 kHz. All sample rates are supported without resampling to avoid any possible loss in accuracy.

J-Scope ~ Oscilloscope VST Plugin


J-Scope is a VST oscilloscope plugin, which can prove invaluable to anyone who develops audio software and has a need to diagnose problems or visualise waveforms.

In operation it is very similar to a real oscilloscope, and most controls will be familiar to anybody who has used a hardware ‘scope. The addition of a control for phosphor decay time allows the examination of rapidly changing waveforms as well as slowly evolving sound envelopes.

J-Scope accepts a stereo signal, and can display it in several modes:

  • Two separate traces, L and R
  • Single trace, sum of L and R
  • Single trace, difference between L and R
  • X/Y (Lissajous) plot, L vs R
  • X/Y (Lissajous) plot, Sum(L+R) vs Diff(L-R)
