20 Hz to 20,000 Hz, which covers the full range of human hearing. You can enter any exact value. Common frequencies: 440 Hz (concert A), 261 Hz (middle C), 1000 Hz (standard test tone).

Sine produces a pure, smooth tone with no harmonics. Square is buzzy and hollow, used in retro game audio. Sawtooth is bright and harsh with all harmonics present. Triangle is softer than square, closer to sine but with a subtle edge.

Yes. Set the volume to a comfortable level and slowly sweep through frequencies to find where your hearing drops off. Most adults can hear up to 15,000-17,000 Hz. This is not a medical device, but it gives a useful indication of your frequency response.

Yes. Type 432 into the frequency input and press Play. You can generate any exact frequency for instrument tuning, sound healing, or calibration purposes. Common tuning references include 440 Hz (standard), 432 Hz (alternative), and 528 Hz.

Many people use tone generators to identify the frequency of their tinnitus by adjusting until the external tone matches what they hear internally. Start at 4000 Hz (the most common tinnitus frequency) and adjust up or down. Consult a hearing specialist for medical advice.

Yes. Switch to Noise mode and choose between white noise (equal energy at all frequencies, good for focus and audio testing), pink noise (balanced and natural, popular for sleep), or brown noise (deep rumbling, great for masking and calming). Play instantly or download as WAV.

Binaural beats play two slightly different frequencies, one in each ear, creating a perceived pulsing tone at the difference frequency. Switch to Binaural mode, set a base frequency and beat frequency, and use headphones. Presets include Delta (deep sleep), Theta (meditation), Alpha (relaxation), and Beta (focus).

Yes. Set your desired noise type or binaural beat configuration, choose a duration (up to 60 seconds), and click Download WAV. The file is generated at 44.1 kHz, CD quality. For binaural beats, the file is stereo with different frequencies in each channel.
