JoEunsoo releases Transient Pepper, a FREE transient enhancer plugin

JoEunsoo has released Transient Pepper, a currently free plugin (normally $14) for macOS and Windows that uses transient detection to layer rhythmic noise onto your audio.

Transient Pepper is available as a free download until November 1, 2025.

At first glance, Transient Pepper might look like a typical transient shaper. But it’s not.

Instead of adjusting the volume envelope of your transients, it analyzes them and adds a layer of noise, essentially using transients to “trigger” noise bursts. It’s like layering a shaker with your snares or hi-hats, except the noise is dynamic and perfectly locked to the transients in your track.

This makes it super handy for subtly enhancing drums and percussion without going the traditional transient designer route. Instead of making your transients louder or sharper, it adds a bit of texture so they cut through the mix more naturally.

The interface is dark and easy on the eyes, which I always appreciate.

There’s a central waveform display that shows exactly how the plugin responds to incoming transients. On the left, you’ll find controls for the Transient Detector section, including Threshold and a BPF (band-pass filter) with adjustable frequency.

You can link the left/right channels and toggle the filter on or off.

Below that are large Attack and Release knobs that control how the noise envelope reacts to the transients. It’s similar to a standard envelope shaper but applied to the generated noise instead of the input signal.

The Noise Shape section on the right lets you fine-tune the tone and stereo width of the noise using a Tilt EQ and Mid/Side controls. You also get a dedicated knob for Noise Gain, as well as Dry/Wet and Output Gain controls to blend everything into your mix.

There’s also a helpful Wet Solo button, making it easy to preview just the generated noise layer.

It’s a pretty immediate effect. You hear the results right away, and I think it’s a lot more intuitive than a standard transient shaper.

But in my experience, after a quick test earlier today, it really shines when used subtly. If you overdo it, your percussion might start sounding like it’s simply layered with an extra shaker or vinyl noise.

But with the right balance, it’s a super quick and clever way to highlight transients without adding harshness.

Transient Pepper is available in VST3 and AU plugin formats for Windows and macOS. It supports macOS 10.13 and newer (Intel and Apple Silicon) and Windows 10 or later (64-bit only). You’ll need to register for a free account to activate the license, but there’s a 30-day trial that works without registration.
