OSC / SOURCE
PITCH sets the base note and SIREN LEVEL sets the source volume. SQR is hard and direct, SAW is rough, TRI and SIN are rounder, while NOIZ removes most of the pitched character.
DUB SIREN DECK
A browser-based dub siren with oscillator, ZAP, LFO, filter, echo, reverb, built-in riddims and recording in one performance deck.
This is the best deck to start with. OSC shapes the source, LFO moves the pitch, ZAP creates short sweeps, and ECHO CHAMBER throws the sound into space. Each section stays independent, so you can build the effect while playing.

A free browser dub siren
DUB SIREN DECK is a browser music tool for playing dub sirens, ZAPs, echo and reverb. No install or account is required. Layer a siren over the built-in riddim, then save the performance with browser recording.
First five steps
- Open the deck and select a preset such as AIR RAID.
- Stay in SIREN mode and press the large performance pad to start audio.
- Move RATE and DEPTH to set the speed and range of the pitch movement.
- Raise DELAY and FEEDBACK gradually, then listen after releasing the pad.
- If needed, start a built-in riddim and place short siren hits in the open spaces.
Basic controls
LFO / MODULATION
RATE controls movement speed and DEPTH controls pitch range. The LFO waveform changes the motion from smooth sweeps to stepped alarms and one-way rises.
ZAP / FILTER
ZAP uses SWEEP for range, SPEED for travel time and REPEAT for bursts. Lower FILTER CUTOFF for a darker sound and raise RESO to emphasise the edge.
ECHO CHAMBER
DELAY sets the repeat interval, FEEDBACK sets how long it returns and REVERB adds a tail. Lower MASTER before pushing FEEDBACK into self-oscillation.
Practical setups
Short signal
Use SQR, low DEPTH and about 40% FEEDBACK. Tap the pad and leave only two or three repeats.
Deep space
Choose TRI or SIN, darken the filter, add reverb and lengthen the delay. Let one hit breathe.
Clash pressure
Use a fast ZAP, increase REPEAT and choose a CLASH-style echo. Drop it into breaks rather than holding it continuously.
Save and export
Press REC before performing, stop when the take is complete, then use SAVE to download the recording. Check MASTER and FEEDBACK first so self-oscillation does not cause a sudden level jump.
What this tool does not do
- This tool focuses on one sound or pattern task rather than final mixing.
- Keep output level conservative before pushing feedback, drive or repeated effects.
FAQ
- Is it free?
- DUB SIREN DECK is free to use in the browser.
- Do I need to install anything?
- No. Open the tool in a current browser to start.
- Can I save or export the result?
- Press REC before performing, stop when the take is complete, then use SAVE to download the recording. Check MASTER and FEEDBACK first so self-oscillation does not cause a sudden level jump.
- What should I try first if it does not work?
- Press a control inside the page once to unlock browser audio.
Troubleshooting
- Press a control inside the page once to unlock browser audio.
- If the sound runs away, lower FEEDBACK, SIREN LEVEL and then MASTER.
- On a phone, close FULL CONTROLS when you need the larger performance surface.
- If recording is unavailable, try a current version of Chrome or Safari outside private browsing.
