What's inside
The five, one by one

24-band dynamic EQ
A-Quasar Pro
The EQ for when the rest fall short: 24 bands, each one dynamic or spectral, in stereo or on a single channel, in Mid or in Side.
- Three phase modes: Zero Latency, Natural Phase and Linear Phase, the last with five resolutions
- EQ Match and Spectrum Grab: copy a reference's spectrum or grab a peak straight off the analyser
- Collision warnings between instances: see where your vocal clashes with the beat
- Auto gain, A/B, undo and redo, a piano on the frequency axis and MIDI Learn
Formats: macOS (universal, Intel and Apple Silicon), VST3, Audio Unit and Standalone. Windows: 64-bit VST3.


Multiband saturator
A-Magnetar Pro
Up to six bands, each with its own saturation, and crossovers built so that splitting the signal doesn't change it: with the bands unsaturated, the sum stays within 0.01 dB from 40 Hz to 16 kHz (measured on its bench).
- Ten saturations per band, with drive, mix, level, pan, dynamics and feedback
- Oversampling from 1× to 16×, in L/R or M/S
- Modulation: two LFOs, two envelope followers and an eight-slot matrix to drive, mix, level, pan and crossovers
- Harmonic anchor: a crossover can follow the note of the source
Formats: macOS (universal, Intel and Apple Silicon), VST3, Audio Unit and Standalone. Windows: 64-bit VST3.

Modern compressor
A-Gravity Pro
A single-band compressor for everyday work, with seven styles and a control of its own, GRAVITY, that tilts the compression towards the body of the sound or towards its peaks.
- Seven styles: Clean, Punch, Vocal, Bus, Opto, Mastering and Pump
- Lookahead up to 20 ms and oversampling up to 8×, in L/R or M/S
- External sidechain with its own EQ and listen, plus Pitch Lock: the sidechain follows the note of the source
- A draggable transfer curve, measured within 0.004 dB of its formula, and aligned parallel mix
Formats: macOS (universal, Intel and Apple Silicon), VST3, Audio Unit and Standalone. Windows: 64-bit VST3.

Key, scale and tempo detector
A-Radar Pro
Put the A-Radar Pro on a track and it tells you the key, the scale and the tempo. It doesn't touch the signal or add latency: it only listens.
- A radar on the circle of fifths: a key shows up as an arc of seven notes in a row, so you can tell it apart from a pile of loose notes at a glance
- The sweep turns at the detected tempo, so you can see whether it caught the pulse
- Four views: Radar, Chroma, Tempo and History
- Tuning reference from 415 to 465 Hz for vinyl or tape material, LOCK to hold the reading, and the project tempo as a hint
Formats: macOS (universal, Intel and Apple Silicon), VST3 and Audio Unit. Windows: 64-bit VST3.

Loudness meter · free, inside the pack
A-Parallaxfree
A loudness meter to ITU-R BS.1770-4 and EBU R128, with twelve ways of looking at the mix. It doesn't touch the signal or add latency, checked bit for bit.
- Checked against ffmpeg (
ebur128) on six real mixes: integrated, range (LRA), momentary and short-term within ±0.05 LU, and true peak within ±0.1 dB - The same at 44.1, 48, 88.2, 96 and 192 kHz, and with blocks from 32 to 4096 samples
- Twelve visualisers for the same measurement
Formats: macOS (universal, Intel and Apple Silicon), VST3 and Audio Unit. Windows: 64-bit VST3.
What you get
All five plug-ins, each with its installer for macOS and Windows, and a single licence key that activates the four Pro plug-ins on two computers. Updates are included. A-Parallax needs no key.
The installers are not signed with a paid certificate: macOS will say it can't verify the developer. It's explained step by step on the download page.
