A complete set of DSP for consumer audio. Get your own sound and effects. Dynamics, advanced fir and more
A scientific audio processor for macOS.
Everything your Mac plays — music, video, a browser tab — runs through a full DSP rack before it reaches your speakers. No drivers. No kernel extensions. No administrator privileges. You open the app and it works.
BUILD YOUR OWN CHAIN
Twenty modules, and you decide which ones are in and in what order: 31-band graphic EQ, parametric EQ with draggable nodes, a linear-phase parametric that shapes tone without touching phase, high and low cut filters in Butterworth, Linkwitz-Riley and Bessel, an all-pass bank for phase alone, compressor, multiband compressor, noise gate, brickwall maximizer, FIR convolver, reverb, stereo width with mid-side, per-channel delay and polarity, and an automatic feedback killer.
Add a module, remove it, drag it up or down. Order changes sound — put the EQ before the compressor, then after, and hear two different instruments from the same settings. Every action can be undone.
THE INSTRUMENT IS INSIDE
Most processors ask you to trust the curve they draw. This one measures itself.
A copy of the signal is taken at the input of the chain and another at the output. Both are aligned by the chain's own declared latency and compared with a dual-channel FFT — the same technique used to measure a loudspeaker in a room, applied here to our own arithmetic. You get magnitude, phase, and coherence.
Coherence is the honest part. Where it falls, the measurement is not to be trusted, and the display says so instead of drawing a confident line over nothing. Switch on a compressor and watch it collapse: dynamics break the assumption that makes transfer measurement valid, and the program tells you twice — the coherence drops on its own, and the module flags itself as non-linear. Two independent witnesses.
There is also a real-time analyser, a theoretical curve for what the filters promise, an ITU-R BS.1770 loudness meter, a signal generator with pink noise, tones and sweeps, and a resource monitor.
WHAT WE PROMISE, AND HOW WE PROVE IT
With every module off, the output is bit-identical to the input. Not "transparent enough" — identical, verified with a byte-for-byte comparison.
Every filter is checked against closed-form theory to better than 0.005 dB. Linkwitz-Riley sums flat to within 0.000 dB. The linear-phase EQ holds its group delay constant to two hundred-billionths of a sample.
Every module declares its latency and the app shows the total, always. Latency is not a sin to hide — it is the price of certain mathematics, and you should know what you are paying.
The output is guarded at −0.1 dBFS by a limiter enforced in the kernel. Push everything you like: the digital output will not clip.
BUILT TO LAST
The processing core is plain C99 — the same code compiles for Linux and embedded ARM. The interface is native Swift. Nothing in between.
Save your work as a preset and share it. Start in BASIC with one EQ and a fader, or in TOTAL with the whole laboratory.
Bring your own curiosity. The numbers are there to keep you honest, not to keep you out.
