This free filter plugin is derived from the renowned mpressor plugin's filter section, designed to enhance your audio's frequency balance with precision. It excels at transforming the tonal character of sounds, such as adding punch to muffled snares or smoothing out harshness from active pickups, while also being ideal for crafting distinctive Dub and LoFi effects. Its straightforward interface features two main controls, enabling quick and effective adjustments without overwhelming complexity.

The plugin specializes in adjusting the balance between high and low frequencies by shifting the gain around a variable center frequency. This approach works similarly to a pair of scales, where increasing the gain boosts either the highs or lows while simultaneously attenuating the opposite range. The center frequency is adjustable across a wide spectrum, from deep bass frequencies up to upper midrange or treble, depending on the selected range, allowing users to fine-tune the tonal emphasis precisely.

In addition to its flexible frequency range, this filter changes its character depending on the EQ gain settings. At extreme settings, it morphs between low pass and high pass filters, offering dynamic tonal shaping options. This makes it an excellent tool when a basic shelving filter is too limited and a fully parametric equalizer is more than needed, striking a perfect balance for creative and corrective audio processing.
