# Make Game Audio During a Jam Without Leaving the Browser
A good game sound effect needs to communicate an action quickly. A bright pitch rise can read as a jump or power-up, a fast downward sweep can feel like a laser or falling object, and a noisy decaying burst can suggest an explosion. This generator turns those familiar arcade patterns into editable browser audio. Pick a preset, listen immediately, and adjust the signal while the waveform preview shows how the sound changes over time.# What the Controls Change
Pitch and movement
The tone controls define the identity of the sound.
- Start frequency sets the initial pitch of the oscillator
- Pitch sweep moves toward a calculated end frequency
- Vibrato adds a gentle periodic pitch movement
- Square, sawtooth, sine, triangle, and noise create different harmonic textures
Shape and texture
The dynamics and texture controls define how the sound lands.
- Length controls the time available for the effect to speak
- Decay makes the amplitude fall away faster or more gradually
- Low-pass filtering softens bright high frequencies
- High-pass filtering removes some low-frequency weight and noise mix adds grit
# A Practical Recipe for Common Game Events
| Event | Useful starting point | First adjustment to try |
|---|---|---|
| Explosion | Noise with a low pitch | Increase length and lower the low-pass filter for a heavier burst |
| Laser | Sawtooth with a falling sweep | Shorten the length and raise the high-pass filter for a sharper attack |
| Jump | Square with a rising sweep | Reduce decay to keep the upward motion audible |
| Coin | Square with a short rising sweep | Raise the start frequency for a brighter pickup sound |
| Power-up | Triangle with a long rising sweep | Add a little vibrato for a more animated result |
