Linear or logarithmic sine wave frequency sweeps. Option for stereo uncorrelated noise, or mono correlated noise. Brown noise falls off at 6 dB per octave. Pink noise falls off at 3 dB per octave (в‘ dB). Produces white noise, pink noise, and brown noise. Anti-aliased square waves, sawtooth waves, and triangle waves are generated with aliasing kept to -54 dB or less. Extends the frequency range down to 1 Hz, and adds stereo control and buttons to increment the frequency in steps. Frequency control via logarithmic knob or keyboard input.

The app includes a free sine wave generator that generates signals from 20 Hz to 20 kHz, with a 48 kHz sample rate, 16-bit samples, and 96 dB of dynamic range. The basic app produces sine waves, and it can be extended and customized (via in-app purchases) to produce white noise, pink noise, frequency sweeps, and (on iPhone 4 and better) square waves, sawtooth waves, and triangle waves. Signal Generator is an app that produces audio test tones.
