Morph two sources, match a reference or shape the signal.
Blend or cross-synthesize two changing spectra, build a patchable live effects graph, measure one recording against a tonal reference, apply a custom response or suppress moving resonances. Then continue through 36 local processors for dynamics, texture, movement and space.
Quick answer: Choose by signal path: Spectral Morph creates a changing two-source hybrid, Match EQ derives one bounded reference correction, IR Convolver applies an uploaded response, and Dynamic EQ reacts to changing energy.

36 tools, grouped by job.
Morph, match and convolve with intent
Three focused workflows cover time-varying two-source morphing, reference-derived tonal matching and custom convolution. Each keeps source relationships and local export visible.
All Effects tools
Live multi-effect patcher
Wire serial and parallel branches, bypass stages and compare a complete local processor graph before one deliberate export.
Reference, resonance, precision dynamics & tone
Derive a bounded reference correction, suppress moving resonances, control responsive bands or the full spectrum, then finish the level structure.
Dynamic Resonance Suppressor
An adaptive multiband resonance suppressor that follows moving whistles, ringing notes and harsh peaks instead of applying one fixed equalizer cut.
Open Dynamic Resonance Suppressor β βAudio Match EQ
A reference-matching equalizer that measures the average spectral difference between a target and reference recording, then derives a smoothed and bounded correction for the target.
Open Audio Match EQ β βDynamic EQ
A parametric equalizer whose selected bands change gain only when energy around their own frequency crosses a threshold.
Open Dynamic EQ β β«Multiband Compressor
A three-band dynamics processor that separates low, mid and high ranges, follows each band independently and recombines them after separate compression and makeup gain.

A creative local effect that combines seeded surface noise, dust impulses, wow, flutter, bandwidth loss and gentle nonlinear wear without reducing digital bit depth.
Open Vinyl Effect βSpace, echo & spectral motion
Morph two spectra, apply responses, create sustained spectra, depth, repeats, phase sweeps, sidebands and stereo movement.
Spectral Morph
A two-source frequency-domain processor that creates a new hybrid by blending or cross-synthesizing changing spectra frame by frame rather than applying one static reference curve.

A local phaser that sweeps a stable cascade of all-pass filters to move phase-cancellation notches without using a delayed copy.
Open Online Audio Phaser β βοΈTremolo & Auto Pan
A local modulation tool that pulses amplitude, moves level between stereo channels with equal-power panning, or combines both motions.
Open Tremolo & Auto Pan β βRing Modulator
A local ring modulator that multiplies every source sample by a free-running or tempo-synced carrier to create amplitude motion and audio-rate sidebands.

A headphone-focused spatial effect that moves a track around the stereo field and blends in a short hall ambience.

Build faster, slower and atmosphere-heavy versions for creative edits.
Slowed + Reverb
A one-page editor that slows a track and adds a hall-style reverb tail for a spacious slowed-and-reverb version.
Open Slowed + Reverb β β‘Nightcore
A classic nightcore creator with direct-rate and target-BPM modes that raise tempo and pitch together and disclose the exact coupled change.
Open Nightcore β π΅TikTok Slowed
A preset edit that slows the source to about 80 percent speed and adds a medium hall reverb.
Open TikTok Slowed β πNightcore Reverse
A slower, reverb-heavy counterpart to nightcore: it reduces playback speed and pitch for a dramatic edit, but it does not reverse the waveform.
Open Nightcore Reverse β π΄Vaporwave
A deep slowdown plus long cathedral-style reverb for creating a hazy vaporwave-inspired version of a track.
Open Vaporwave β πSped Up Audio
A tempo-focused speed-up tool that shortens a track while attempting to keep the original musical pitch.

Limits and privacy
Core browser DSP keeps selected audio on the device and avoids an upload queue. Optional model-based or system-speech modes are disclosed on their own pages. Practical limits come from decoded duration, channel count, algorithm memory and the current device; compressed audio can expand substantially in memory.
