Every plugin here started as a complaint on a session. None of them ships until it earns its place on one.
Fireball Audio is a one-person plugin house run by a working producer and mixing engineer, in Toronto. Audio Unit and VST3, macOS universal.
The distinguishing thing is not the feature list. It is that the DSP is measured rather than eyeballed, and nothing is claimed here that has not been asserted in a test that fails the build.
The method is borrowed from test-driven software and pointed at audio. It exists because ear-only development produces plugins that sound plausible and measure badly, and because a one-person shop cannot afford to discover that after release.
Every release is auval-validated, signed and notarised before it goes to anyone.
Jesse Heifetz is a producer and mixing engineer working in two scenes at once, and the plugins come directly out of both.
Drum & bass and jungle, most closely associated with Metalheadz — on the label since 2018, in a long-running partnership with Gremlinz. Also Warm Communications, Paradox, Architecture, UVB-76, Rupture LDN, Dispatch and Future Retro London.
Modern boom bap for underground rap. Two Birds, with Asun Eastwood and Lord Juco, made Hip Hop Golden Age's 40 Best Underground Street Rap Albums of 2025. Also runs Fireball Studios in Markham, taking mixing and mastering work for other artists.
The relevance is not the credits. Jungle and boom bap are both sample musics — both built on breakbeats, both entirely dependent on what happens to recorded sound when you push it through something. Two decades of that, plus engineering other people's records, produces very specific opinions about saturation, spring reverb and delay. The catalogue is those opinions compiled.
The test discipline exists for the same reason: the person writing the DSP is also the person who has to mix through it on Monday.
