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. Frequency control via logarithmic knob or keyboard input. • Pro Tone Generator. (Optional in-app purchase). Extends the frequency range down to 1 Hz, and adds stereo control and buttons to increment the frequency in steps. Anti-aliased square waves, sawtooth waves, and triangle waves are generated with aliasing kept to -54 dB or less. • Noise Generator. (Optional in-app purchase).

Leave a Review Audio Signal Generator
  • Needs update

    Was good for years until now on new iPhone models it glitches out and the sound sweep can sound sound alien like. Only the clean sweeps will work for me no my using either left or right sweeps.
  • College

    This is an amazing app especially when pursuing a career in audio engineering/music production
  • Didn’t work

    Couldn’t get it to make any sound at all on iPhone 12 Pro
