A fully free and self-contained modular synthesizer based on the popular VCV Rack. Available in AudioUnit/CLAP/LV2/VST2/VST3 plugin formats and as a standalone app for FreeBSD, Linux, macOS, Windows and the Web.
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.
Filtron is a 12dB state variable filter that can smoothly transition between lowpass, bandpass, and highpass. It is capable of self-oscillation with resonance levels that can reach up to 11! Filtron also features a fat sounding internal saturation algorithm and a sizzly post overdrive with two modes to choose from: cold and hot.

The plugin is very unique in the sense that it gives you full control over all aspects of the modelled circuit. All values of all the capacitors, resistors etc. can be tuned by the user.
This is a free plugin. It comes in all the usual plugin formats (VST/VST3/AU/AAX), for 32 and 64 bit hosts, and for Mac Intel & Silicon.
Correlometer is an analog-style stereo multi-band correlation meter.
Multi-band correlation meter is an advanced way to check for presence of out-of-phase elements in the mix. Broadband correlation metering reports overall phase issues and may misrepresent problems present in select spectral bands, while multi-band correlation meter easily highlights problems present in mid to high frequencies that are not easily heard by ear, but may still reduce clarity of the mix. Another application of multi-band correlation metering is phase- and time-aligning of channels and tracks, especially bass and bass-drum pairs, guitar mic and D.I. source pairs, two-microphone stereo recordings, etc.
Correlometer can display 4 to 64 individual spectral bands, with adjustable band quality factor that controls the degree of band’s selectivity. Averaging time of correlation estimator can be adjusted. Correlometer supports side-chain inputs for easy correlation estimation between separate audio tracks.
MJUC jr. is the little brother of the colorful MJUC.
It’s a variable-mu design with lots of vibe, capable of smooth leveling but also heavy pumping effects. With its two gain stages and interstage transformer simulation it offers a very deep and lively soundstage.
The three-position timing switch not only controls the attack and release times of the unit, but also the slew rate of the transformers and the timing of the other parts of the circuitry, that are directly influencing the generated harmonics (saturation).
Marvel GEQ is a free linear-phase 16-band graphic equalizer AudioUnit, AAX, and VST plugin with multi-channel operation support (supporting up to 8 input/output channels, audio host application-dependent) for professional music production applications. Marvel GEQ offers extensive internal channel routing capabilities, and supports mid/side channel processing.
Add an authentic edge to your music with this essential collection of vintage drum sounds captured at one of the few remaining analogue recording studios: KERWAX. Discover two stunning kits — a 1970 Ludwig with 26” bass drum (as made famous by John Bonham of Led Zeppelin) and a 1940s custom kit fitted with original calfskin heads for a warm, rounded tone. Produced and engineered by Christophe Chavanon.
4Front E-Piano is a small single sound instrument without any settings that reproduces a timbre, which is similar to DX-7 type e-piano. It is available as VSTi for Windows, and as an AudioUnit, VSTi and RTAS for Mac.
This instrument is small on memory and CPU usage and was found useful by many users and software developers as a plug & play e-piano module, which does not require any configuration or adjustment.
There is also 4Front R-Piano, which replicates a different type of E-Piano.
TDR Kotelnikov is a wideband dynamics processor combining high fidelity dynamic range control with deep musical flexibility. As a descendant of the venerable TDR Feedback Compressor product family, Kotelnikov has directly inherited several unique features such as a proven control scheme, individual release control for peak and RMS content, an intuitive user interface, and powerful, state of the art, high-precision algorithms.
With a sonic signature best described as “stealthy”, Kotelnikov has the ability to manipulate the dynamic range by dramatic amounts, while carefully preserving the original tone, timbre and punch of a musical signal. As such, it is perfectly suited to stereo bus compression as well as other critical applications.
The concept is “proudly digital” in the sense that it doesn’t try to emulate any previously existing device. This is the original!
Features:
64bit multi-rate processing structure for highest accuracy
“Delta” oversampled signal path (bit transparent at 0dB gain reduction)
Super fast, yet natural sounding compression
“Crest factor” based control scheme offering independent release controls for peak and RMS events
Flexible sidechain highpass filter
Advanced stereo linking options optimized for the stereo bus
Delta preview mode previews the difference between compressed and original signal
Latency compensated, click free bypass (i.e. processing never interrupted)
