IPA 25 Black Friday pricing is 53% off, $69, with the deal ending Dec 7, 2026, on Pulsar Audio's multi-VCA dynamics processor plugin.
The maker describes it as classic VCA compression extended with modern control. You get selectable circuit topologies, a clipper and limiter, a visual sidechain and modular signal flow in a single IPA 25 plugin.
According to Pulsar, the detector reproduces how the hardware unit behaves: it reads level by averaging, the knee shape shifts with the ratio setting, and the release time adapts to the incoming material.
The detector and settings stay the same across all four modes. What changes is the harmonic fingerprint of the gain-reduction stage, and each mode is gain-matched so you can swap without rebalancing.
The drive control decides how much of that harmonic flavor you hear.
Pulsar treats the sidechain as a creative tool, not an afterthought. A Punch Selector shifts detector focus across the spectrum in NORM, MID and LOUD modes.
A four-band visual sidechain EQ lets you draw which frequencies drive gain reduction. Stereo linking controls how and when the two channels share reduction, and an external sidechain input covers ducking and pumping.
The built-in clipper trims spikes instantly and adds harmonic weight. That also keeps downstream compressors from overreacting.
The limiter uses a control-point algorithm that only steps in where overshoots occur. Sustained lows pass untouched, while transient-heavy material gets saturation that its own spectrum masks.
You can place the module pre-comp, pre-mix inside a parallel path, or post-mix as a maximizer-style ceiling across the bus.
Timing tools shape the envelope:
A zero-latency mode is there for tracking, and oversampling is available for mixing and mastering. The maker says the design is CPU-efficient, so you can run multiple instances across a large session. Real-time visuals show compression, spectrum and detector behaviour.
Every Pulsar plugin comes with a lifetime license, free lifetime updates and customer support, with no subscription.
Yes. The IPA 25 Black Friday deal is 53% off, bringing the Pulsar Audio plugin to $69, and it ends Dec 7, 2026. Pulsar says its plugins use a lifetime license with free lifetime updates and no subscription.
IPA 25 has four: Clean VCA, Original VCA, V-Mu and N-Diode. The detector stays constant while the harmonic fingerprint of the gain-reduction stage changes. Each mode is gain-matched, and the drive control sets how much harmonic content you dial in.
Yes. The clipper trims spikes and adds harmonic weight, while the limiter only steps in where overshoots occur. You can place the module pre-comp, pre-mix in a parallel path, or post-mix as a ceiling across the bus.
Yes. A zero-latency mode is built in for tracking, so performers stay in the groove. For mixing and mastering you can switch to oversampling, which the maker says avoids aliasing, and the design is described as CPU-efficient.
