About
Play test tones and watch the waveform change in real time — an oscillator experiment app for iPhone. Control frequency, volume, panning, a low-pass filter, and AM / FM modulation right from your device. Whether you're checking a speaker, testing a DIY audio circuit, or learning synthesizer basics, this app covers it. FEATURES - Generate test tones and drone sounds - See the waveform update in real time - Fine-tune stereo panning - Hear high-frequency rolloff with the low-pass filter - Explore tremolo-like movement with AM modulation - Explore vibrato-like pitch variation with FM modulation - Hear interference and beating with two channels (Full Version) - Save and recall settings as presets (Full Version) GREAT FOR - Quick checks for speakers, earphones, and amplifiers - DIY effects pedal and audio circuit testing - Learning synthesizer waveforms, filters, and modulation - Classroom and workshop demonstrations - Exploring drone tones, beating effects, and modulated sounds FREE AND FULL VERSION The core oscillator and waveform display are completely free. Ad removal, two-channel mode, and preset saving are available as an in-app purchase. PLEASE NOTE This app is designed for audio experiments and quick checks — not precision measurement. Always start at a low volume, and be especially careful when using earphones, headphones, or external speakers.
