English listing
Short description
Synthesize tones, mix oscillators, explore sweeps and export stereo WAV audio.
Full description
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.
Data safety worksheet
Preparation only. Review the final signed artifact, active advertising and purchase configuration, and provider behavior before completing Google Play declarations.
Audio is synthesized and exported locally. Presets, configurations, comparison settings and language are stored on the device. The app does not require its own account, microphone, location or audio-upload service. Exported WAV files are saved to the user-selected destination.
Internet access supports Google Mobile Ads, UMP and the prepared Google Play purchase flow. Development test-ad builds show Library banners only outside playback and export, subject to the implemented consent checks. Google services may process IP addresses, approximate location, identifiers, interactions and diagnostics; test identifiers do not mean no data is transmitted. Google privacy: https://policies.google.com/privacy .
Google Play handles the planned one-time Remove Ads purchase; the developer does not receive payment-card details. The app verifies and stores signed purchase information privately for offline access and restoration. Production purchase configuration is not active. Android automatic app backup is disabled. A chosen export provider may synchronize WAV files under its own terms.
Media
Capture at least two authentic screenshots from the final app. Do not use simulated screens, synthetic medical fixtures or old-brand captures. Screenshot language must reflect the actual app; English captions do not imply an English-only interface.
