Find your tone
Inside the Freequency app you'll find the tone maker. It lets you build a computer-generated tinnitus tone and fine-tune it until it closely matches the sound you hear inside your head. When you first open Freequency you're guided straight to the tone maker, and you can return to it at any time to add another tone or to experiment with different settings.
Under 'Manage tones' you can also edit or delete tones you've created before. Always use the tone maker with earbuds or a Bluetooth headset — never through your phone's loudspeaker — so that pitch, volume, and stereo balance remain accurate.
Shape
Pick the waveform that feels closest to your tinnitus. Each waveform has its own character — cycle through them until one stands out as familiar. If you don't hear anything yet, adjust the frequency and amplitude sliders after selecting a shape.
Pure, square, saw and triangle waves
Filtered and band-limited noise
Match the texture of your tinnitus
Frequency
Use the frequency slider to set the pitch in Hertz. If you already know the frequency of your tinnitus, enter it directly. Otherwise, drag the slider close to what you hear and use the 10 / 50 / 100 Hz fine-tune buttons for precise adjustments. Take your time — it helps to compare multiple tones across different days.

Amplitude
Use the amplitude slider to match the loudness of your tinnitus. You can boost the tone up to 200% of the base volume. Only raise the amplitude when your phone's system volume is already at maximum — that way the in-app level stays representative of what the app will play during a session.

Pan
Use the pan slider to distribute the tone between your left and right ear. If you only hear your tinnitus on one side, push the balance fully in that direction (for example 100% left / 0% right). The app uses this balance whenever the tone is played back during a session.

Mixing multiple tones
Tinnitus rarely sounds like a single pure tone. The tone maker lets you combine multiple sounds into one profile — for example a high-pitched beep layered with a low hum. Check the tones you want to include and they'll all play together during your sessions.
