How to Generate a Tone in 4 Easy Steps
- 01
Select a Waveform
Choose from four waveform types: Sine for a pure tone, Square for a buzzy sound, Sawtooth for a bright texture, or Triangle for a soft tone.
- 02
Set the Frequency
Use the slider, type a value, or pick a musical note preset. Range from 20 Hz (deep bass) to 20,000 Hz (ultrasonic).
- 03
Adjust Duration & Volume
Set the tone duration from 1 to 30 seconds and adjust the volume level to your preference.
- 04
Generate & Download
ask Magica to generate the result Tone' and listen to the result. Download the WAV file for use in any audio project.

Audio Engineers
Test speakers, headphones, and audio equipment with pure tones across the full audible frequency range.
Sound Designers
Create base tones for layering in sound design projects, from deep bass drones to high-pitched accents.
Teachers & Students
Demonstrate waveform properties, frequency concepts, and audio fundamentals in physics or music classes.
Hearing Test Users
Check your hearing range with tones from 20 Hz to 20 kHz to identify your personal audible frequency limits.
Meditation & Focus Creators
Generate soothing tones for meditation tracks, binaural beats, or ambient focus soundscapes.
Tips for Best Results with Our Tone Generator
Use sine waves for pure reference tones
Sine waves produce the cleanest, most fundamental tone with no additional harmonics — ideal for tuning instruments, testing speakers, and calibrating audio equipment.
Lower the volume for high frequencies
High-frequency tones above 4 kHz can be harsh at full volume. Start with a lower volume setting and increase gradually to protect your hearing.
Use musical note presets for tuning
The note presets provide exact standard pitch frequencies, saving you from looking up values when tuning instruments or testing musical intervals.
Try different waveforms for creative use
Square and sawtooth waves have a rich, buzzy character that works well for retro sound effects, electronic music elements, and alarm-style tones.
Frequently Asked Questions About Our Tone Generator
Is this tone generator really free?
This workflow is available through Magica; access and usage follow your Magica plan.
What is the difference between the waveform types?
Sine waves produce a pure, smooth tone with no harmonics — ideal for tuning and testing. Square waves have a hollow, buzzy quality. Sawtooth waves are bright and rich with strong harmonics. Triangle waves are similar to sine but slightly brighter and softer than square.
What frequency range is supported?
You can generate tones from 20 Hz to 20,000 Hz (20 kHz), which covers the full range of human hearing. The musical note presets cover the octave from C4 (261.63 Hz) to C5 (523.25 Hz).
What audio format is the output?
The generated tone is saved as a high-quality WAV file — lossless quality suitable for any audio application.
Can I use the generated tones commercially?
Absolutely. The tones are generated mathematically in your browser. There are no licensing restrictions — use them however you like.
Why does my tone have a clicking sound at the start or end?
Our generator applies a brief fade-in and fade-out to eliminate clicks. If you still hear artifacts, try increasing the duration or adjusting the volume.
Is my data uploaded to your servers?
No. All tone generation happens entirely in your browser. No audio data is sent anywhere — your privacy is fully protected.
Can I use this on my phone?
Yes! The tone generator works on smartphones, tablets, and computers. Just open it in your browser. Performance is fast on all modern devices.
What are the best waveforms for testing speakers?
Sine waves are best for speaker testing because they produce a single, pure frequency. This lets you test specific frequency ranges in isolation — sweep from low to high to identify any weaknesses in your speakers or headphones.
Can I create binaural beats with this tool?
You can generate individual tones at specific frequencies needed for binaural beats. Generate two tones at slightly different frequencies (e.g., 200 Hz and 210 Hz), then combine them in an audio editor with one tone in each ear for the binaural effect.
