PRAXIS SCIENCE LAB / ANDROID

Frequency Studio

Synthesize tones, mix oscillators, explore sweeps and export stereo WAV audio.

In testing Not yet available on Google Play.

An Android sound-synthesis workspace, separate from Frequency Sound Generator.

Generate sine, square, sawtooth and triangle waves from 1 to 22,000 Hz. Mix up to eight oscillators with individual frequency, waveform, level, pan and mute controls. Explore linear or logarithmic sweeps, binaural signals, five noise colors, DTMF, a metronome, musical notes and synthesized effects.

Save local presets, compare two configurations and export stereo PCM16 WAV at 44.1 kHz. The signal graph shows synthesized audio, not sound measured through a microphone. Playback stops when the app goes into the background, loses audio focus or headphones disconnect.

All synthesis functions and WAV export remain free. The development configuration supports Google test banners in the Library outside playback and export, with a planned one-time Remove Ads purchase. Commercial purchasing is not configured. Version 0.2.0 is in testing; no Google Play installation or public APK download is offered here.

Using the app

Start at low volume. The digital frequency range does not guarantee that your speaker or headphones can reproduce it, and the level control is not a calibrated sound-pressure measurement. Binaural output is an audio experiment, not a medical treatment or hearing test. Playback and export follow the configured timer and finite signal duration; a longer export may contain trailing silence.
