Frequently Asked Questions
Can I apply multiple effects at once?
Yes! You can stack as many effects as you want and reorder them. Effects are applied in order from top to bottom, so the sequence matters. For example, applying reverb before distortion gives a different result than distortion before reverb.
What's the output format?
The output is a high-quality WAV file (16-bit PCM) at the original sample rate. If you need MP3 or another format, use our Audio Converter tool after applying effects.
Is my audio uploaded anywhere?
No! All processing happens entirely in your browser using the Web Audio API. Your audio files never leave your device. Only background music presets are loaded from our server.
What's the difference between Speed and Pitch Shift?
Speed changes both the tempo and pitch together (like playing a record faster). Pitch Shift changes only the pitch while keeping the same duration — so you can make a voice sound higher or lower without changing the speed.
