Audio Filters Reference
Audio has its own effects chain of 23 filters — restoration, dynamics, normalization, EQ, creative effects, and utility tools — built the same way as image filters: add, reorder, toggle, remove, or hand-edit as JSON (see the JSON editor).
Unlike the image pipeline, audio effects apply in exactly the order you stack them — there's no fixed category ordering, so drag effects into whatever sequence sounds right. A common starting point: restoration effects (Noise Reduction, Declipper, Declicker) first, dynamics and tone shaping in the middle, and loudness normalization last so earlier effects don't push levels back out of range.
Pick an effect below for its full parameter reference.
Repair
Dynamics
De-esser
Tames harsh sibilance — "s"/"sh" sounds — in vocals.
Compressor/Expander
Reduces (or expands) the gap between the loudest and quietest parts of the signal.
Limiter
Caps peaks at a maximum level to prevent clipping.
Gate
Silences audio below a threshold, useful for cutting background noise between words.
Normalize
EQ & Tone
Parametric EQ (5-band)
Five fixed-frequency bands for precise tonal shaping.
High Pass
Cuts frequencies below a cutoff, removing rumble.
Low Pass
Cuts frequencies above a cutoff, removing hiss and harshness.
Bass
Broadly boosts or cuts low frequencies with a shelf filter.
Treble
Broadly boosts or cuts high frequencies with a shelf filter.
Effects
Tremolo
Rhythmic volume modulation.
Flanger
A sweeping, jet-like modulation effect.
Chorus
Thickens the sound by layering slightly delayed, decayed copies.
Echo
A discrete, repeating delay.
Stereo Widen
Increases perceived stereo width using inter-channel delay and feedback.
Extra Stereo
Expands (or narrows) the stereo image by scaling the difference between channels.
