Frequently asked questions
It targets six categories of non-vocal distortion: low-frequency rumble and plosive pops (low-cut filter), 50/60 Hz electrical hum (notch filters), boxy room resonance in the low-mids (boom cut), high-frequency hiss and RF interference (high-cut filter), and quiet background noise between words (noise gate compressor).
The Presence stage is the one that adds rather than removes — it boosts the 2.5–3 kHz range where voice intelligibility lives. This makes speech sound clearer and cut through any remaining background without increasing overall volume.
Yes — every processing stage has an on/off toggle. For example, if your recording has no electrical hum, you can turn off the Notch stage. Disabling stages reduces processing and may preserve more of the original character.
Use the Phone / Video Call preset. It applies a tighter high-pass (150 Hz) and a more aggressive noise gate to compensate for the digital compression artifacts common in VoIP recordings.
No. All six processing stages run locally in your browser using BiquadFilterNode and DynamicsCompressorNode from the Web Audio API. Nothing leaves your device.
