Generate tones and noise with adjustable lowpass filters and panning. Choose from sine, triangle, sawtooth, and square waveforms. Precisely tune frequencies in Hz or MIDI notes.






Create pure sine wave audio tones across a wide frequency range. This tool is ideal for tuning instruments, conducting hearing tests, performing science experiments, and testing audio equipment. Easily adjust frequencies and volume, with support for AirPlay devices.




Generate multiple audio signals with adjustable waveforms, frequencies, and volumes for each channel. Offers presets for guitar and bass tuning, with options to expand channel support.


Generate simple audio tones with four distinct waveforms including sine, square, saw, and white noise. Control frequency, panning, and amplitude with intuitive sliders and numeric input. Ideal for testing audio or creating experimental music.


Generate various audio test tones, including sine, square, triangle, and sawtooth waves. Explore frequency and volume sweeps, noise generation, and custom preset creation. Advanced features like extended frequency ranges and multi-tone playback are available with an upgrade.




This app is a triangle wave synthesizer that can be used as an educational tool for learning synthesis or as a creative instrument for generating pure triangle waves. It supports MIDI input and AUv3 integration, allowing layering with other synths for complex sound textures.


Generate test tones and observe real-time waveform changes. Explore frequency, volume, filters, and modulation effects for audio experiments and learning synthesizer basics.


Create personalized binaural beats for sleep, focus, and meditation. Adjust frequencies to generate custom soundscapes for relaxation or alertness. Requires headphones for optimal experience.






Analyze and generate audio signals with this app, featuring an oscilloscope for real-time waveform visualization and a spectrum analyzer for frequency analysis. It also includes a synthesizer for creating AM/FM modulated audio.








This app translates visual information from your camera into sound using spectral synthesis. Control the sound's amplitude, type, and speed by interacting with the screen and camera feed. Record any generated sound with a simple button press.


Visualize sound waves and analyze their frequency spectrum. This utility displays the waveform of various sounds, from your voice to musical instruments, and reveals their overtone structure. Explore the sonic characteristics of your environment with this straightforward tool.


Learn drum rhythms with a library of play-along music loops. Adjust tempo, instrument mix, and follow notation or audio examples. Ideal for beginner and intermediate drummers.


Explore physics concepts with a spring pendulum simulation. Manipulate parameters like damping, spring flexibility, and mass to observe oscillations. Record and export displacement graphs for deeper analysis.
