Frequently Asked Questions

What are the different waveforms used for?

Sine waves are pure tones for testing. Square waves test amplifier response. Sawtooth and triangle waves are used in synthesizers.

Why would I need different sample rates?

Higher sample rates (96kHz) capture higher frequencies but create larger files. 44.1kHz is standard for CD audio.

Is this tool really completely offline?

Yes, all audio generation happens locally in your browser using Web Audio API. No data is sent to any server.

How It Works

Web Audio API generates the selected waveform mathematically
Audio data is rendered using an OfflineAudioContext
Raw audio samples are encoded to WAV format manually
File is created and made available for download
