Tone Gen Studio

Test speakers, find frequencies, tune instruments, and keep time during practice with Tone Gen Studio. Generate tones, sweeps, and noise, explore your microphone input with the tuner and spectrum analyzer, or practice with the built-in metronome.

Tone generation and speaker testing

• Set a custom frequency or choose a preset tone pad.
• Select sine, square, sawtooth, or triangle waveforms.
• Run linear, exponential, or stepped frequency sweeps.
• Generate white, pink, and brown noise.
• Set burst on and off durations for pulsed tones.
• Adjust binaural carrier and beat frequencies for headphone playback.

Tuning and audio analysis

• View the detected note, frequency, and cents with the microphone tuner.
• Explore input levels with a real-time spectrum analyzer and 1/3-octave RTA bands.

Metronome and practice

• Set a tempo from 20 to 300 BPM or use tap tempo.
• Choose time signatures, subdivisions, accents, and five click sounds.
• Practice with swing, polyrhythms, gradual tempo ramps, and random mute.
• Use a count-in and practice timer.

Start at a low volume and adjust gradually. Binaural playback requires headphones. Speaker response and microphone measurements depend on your device and connected audio equipment.

For musicians, audio engineers, educators, and anyone working with sound on iPhone and iPad.
