What the frequency generator is for

Frequency Sound Generator produces a steady tone at a frequency you pick, from 1Hz to 22000Hz. It suits people who need a known reference tone: producers checking speakers, musicians tuning instruments, and anyone who wants to listen to a single frequency. The listing also names meditation as a use.

Because the range runs from very low rumble to the top of the audible band, the same tool covers both low and high frequency checks. The developer describes it as a simple tool with few controls.

Sine, square, sawtooth and triangle waveforms

The app generates four wave shapes: sine, square, sawtooth and triangle. A sine wave is the purest single tone, with no added harmonics. The other three shapes contain more overtones, which change how the tone sounds through a speaker.

Switching shapes is a single tap on the wave icon in the main menu, followed by choosing the shape you want. This makes it quick to compare how the same frequency sounds in different waveforms.

Testing speakers across low and high frequencies

The 1Hz to 22000Hz range lets you run a tone at the bottom of the scale to check how a speaker or subwoofer handles deep sound, then move up toward the top of the range. The listing presents this as its main use for sound testing.

Set a frequency, play the tone, and listen for distortion, rattles or dropouts at that point in the range. The app generates the tone only. It does not measure the speaker.

Picking musical notes for tuning instruments

Alongside raw frequencies, the notes icon in the main menu gives a list of musical notes to choose from. A note gives you a reference pitch, which is useful for tuning an instrument or matching a sound to a key.

The listing does not say how many notes are included or how they are tuned, so the note list should be read as a pitch reference rather than a full tuning system.
