Build a browser delay effect
Learn how a low-pass filter, delay time, feedback and mix shape a stereo echo in Tune.Toys.
Template: Warm Echo. You will learn: filter tone, delay time, feedback and mix.
- Open Warm Echo and choose Preview to hear it with the included demo input.
- Lower Tone to soften the sound before it enters the delay. Compare a bright cutoff with a darker one.
- Change Time to hear shorter and longer repeats. Raise Feedback gradually to retain more repeats.
- Adjust Mix to blend the effect with the original audio.
- Choose Create from template, then Create to open an independent Toy. Patch shows the signal path; Frame shows the playable controls.
- Save your work. Publish when you want a shorter playable link with a preview image.
For the nodes involved, see Delay and Low-pass filter.
The template
Shape a stereo sound with a low-pass filter, then send it through a delay. Warm Echo is a practical introduction to connecting audio nodes and designing a playable control panel.

Audio2ch
Audio2ch
Audio2ch
Filter cutoff, capped at 0.45 times sample rate. Range: 40–18000 Hz. Default: 3200 Hz. Logarithmic scale. Units: Hz.
Hz
State-variable filter Q. Range: 0.5–12 Q. Default: 0.707 Q. Linear scale. Units: Q.
Q
Selects the implemented algorithm. Choices are discrete and are not LFO targets. Range: 0–5. Default: 1. Linear scale. Units: unitless.
One or two cascaded state-variable stages; notch/all-pass retain their response semantics. Range: 0–1. Default: 0. Linear scale. Units: unitless.
Reduces resonant gain as Q increases. Range: 0–1. Default: 0. Linear scale. Units: unitless.
Audio2ch
Audio2ch
Free delay time. Beat divisions follow engine tempo and are capped at the prepared eight-second capacity. Range: 20–1000 ms. Default: 280 ms. Linear scale. Units: ms.
ms
Signed feedback gain. Matrix rows must have an absolute gain sum of at most one. Range: 0–0.9. Default: 0.35. Linear scale. Units: unitless.
Dry/wet blend. Processing latency is aligned before blending. Range: 0–1. Default: 0.3. Linear scale. Units: unitless.
Selects the implemented algorithm. Choices are discrete and are not LFO targets. Range: 0–3. Default: 0. Linear scale. Units: unitless.
Free milliseconds or tempo-synchronized musical divisions. Range: 0–1. Default: 0. Linear scale. Units: unitless.
Independent per-channel feedback, a ring over all channels, or explicit sparse routes set in the Channels section of Properties. Range: 0–2. Default: 0. Linear scale. Units: unitless.
Audio2ch
Audio2ch
Multiplies both audio channels. 0 silences the signal; 1 leaves its level unchanged. Range: 0–2 ×. Default: 1 ×. Linear scale. Units: linear gain.

Controls
- Tone sets the filter cutoff: lower values soften the sound.
- Time sets the distance between repeats in milliseconds.
- Feedback sends part of each repeat back into the delay.
- Mix balances the original signal with the delayed sound.
