Audio Phaser

About Audio Phaser

Our Audio Phaser is a creative modulation tool that adds a shimmering, sweeping quality to your sounds. Historically popularized in the 1970s for guitars and keyboards, the phaser effect works by creating peaks and troughs in the frequency spectrum that 'sweep' up and down. This results in a characteristic 'whooshing' or 'jet-plane' sound that adds movement and character to any audio track. You can adjust the LFO (Low Frequency Oscillator) speed to control how fast the sweep occurs and the decay to adjust the resonance and intensity. Powered by FFmpeg WASM, this tool provides professional-grade sound design capabilities directly in your browser, maintaining 100% privacy for your creative work.

How to use Audio Phaser

1. Upload your audio track or sound effect to the secure tool area.
2. Use the 'LFO Speed' slider to set the rate of the sweeping effect (0.1Hz to 2Hz).
3. Adjust the 'Decay' slider to control the resonance and feedback of the phaser.
4. Click 'Apply Phaser' to generate the effect using your device's hardware.
5. Listen to the spacey, modulated results in the player and download the file.
