About
We would rather show you the measurement than the adjective.
How these are built
Every plugin here starts as a question about a mechanism. Why does a push-pull valve stage sound different from a single-ended one? Because its topology cancels even harmonics as a matter of algebra. Why does a transformer saturate the bass first? Because flux is the integral of voltage. Model the mechanism and the character follows; model the character and you get a curve someone liked.
The audio engine in each of our 22 plugins is plain C++ with no plugin-framework dependency at all. That is not tidiness: it means the test suite compiles and runs in about a second, which is what makes it practical to measure every claim instead of asserting it. It also means the tests can replace the global allocator to prove the audio path never allocates, rather than putting a comment in the code saying it does not.
When a measurement disagrees with the design, the measurement wins and the disagreement gets written down. Our reverb once reported its damping filters as free; a second measurement showed the benchmark had timed two settings that both ran them, and the 13 ns per sample they really cost was written into its documentation. Our delay keeps a linear interpolator that is six decibels worse than the good one at 16 kHz, because a bucket-brigade device really is doing linear interpolation in charge packets and that top-end movement is the sound rather than a defect.
What we will not do
We do not claim to have modelled a specific piece of hardware unless we have modelled and validated that circuit. Our amplifier simulator names its voicings descriptively and says plainly that none is modelled from measurements of a specific product. Our period-character plugins recreate the technical fingerprints of an era (the bandwidth, the compression behaviour, the harmonic structure, the noise, the stereo conventions) and say plainly that they do not reproduce any named console, tape machine or record.
We do not publish reviews, ratings, user counts or endorsements we have not received. If you find a quote on this site, it came from our own documentation.
And we do not publish audio demos we did not record through the plugin. Where a product page says demos are not published yet, that is because they are not, and we would rather tell you that than fill the space.
Pricing
One list price per plug-in, the same number in pounds, euros and dollars. When we run a sale, the price we cross out is the one people really paid before it, never a figure nobody was charged so that a discount can look larger than it is.
The store looks after your basket too: if a bundle covers what you have chosen for less, it tells you.
