Blackboard EQ Black Friday pricing takes 60% off CalPochi's EQ plugin, so it costs $35.60 until Nov 30, 2026.
The maker pitches it as an equalizer that feels like drawing your curve straight onto the screen. Static EQ, per-band Dynamic EQ, Saturation, L/R and Mid/Side processing and selectable phase modes all live in one interface.
The idea is that you can see how much processing is happening and adjust only where it is needed.
You can add up to 24 bands. Each one has its own frequency, gain, Q, filter type, slope and processing channel.
Eight filter types are on offer:
Cut filters run from 12 to 96 dB/oct. Linear Phase mode adds a Brickwall option on top.
Every band can be routed to Stereo, Left, Right, Mid or Side. That lets you work on just the component you are chasing.
Switch on Dyn and a single band becomes a Dynamic EQ band with Threshold, Range, Attack and Release controls. According to the developer, Blackboard EQ lets you rein in a piercing top end or a clouded low-mid range at the exact moments those issues appear.
The Sat section has Drive and Character controls. It adds texture and colour to the frequency ranges you pick, not the whole signal.
Alt-drag a node to solo that band while you hunt for the right frequency.
Right-click any EQ point to attach a text note. It is a handy way to record why you made a move.
Sketching in FREE Draw happens on screen only, so your sound stays untouched. Your chalk annotations are saved with the session and survive preset changes and A/B comparison.
Zero Latency mode is meant for fast, responsive everyday processing. Switch to Linear Phase and pick a resolution for more precise mixing and mastering work.
The feature list also includes:
