波動 Hysteric Oscillator vs DIVA EVO

An oscillator experiment app that shows the waveform in real time while it plays. Generate sine, square, pulse, sawtooth, and noise from 2 Hz to 20 kHz, and control the filter (low-pass / high-pass) and AM / FM modulation from your device. Export what you made as a video or an audio file. Useful for quick speaker and amplifier checks, DIY audio circuit tests, and learning synthesizer basics. Features - Six waveshapes: sine, square, pulse, sawtooth, harmonics, and noise (White, Pink, or Brown) - Real-time waveform display with L / R in separate colors; tap to switch to a mono trace - Spectrum analyzer: see the frequency content in real time, with guide lines on each harmonic so you can read how much harmonic content the sound has - "Harm" waveshape built from added harmonics: pick which harmonic is loudest with a slider, then set the character with Pure / Full / Odd / Even, and check the result in the spectrum - Frequency from 2 Hz to 20 kHz, with exact numeric entry - Filter: off / low-pass / high-pass, with resonance (Q) and slope (-12 to -48 dB/oct) - AM modulation with five modulator shapes; pulse lets you set the beep length in milliseconds - FM modulation with five modulator shapes: vibrato, trill, siren and hiccup-style pitch movement - Stereo balance control - 42 built-in presets (bandwidth-check sine tones, filter and pulse driven effects) - Export a vertical video (MP4) of the moving waveform for social media (free) - Export audio files (WAV / M4A) with the Full Version - Two channels for interference and beating (Full Version) - Save your own presets (Full Version) Great for - Quick checks of speakers, earphones, and amplifiers - Testing DIY effects pedals and audio circuits - Learning waveforms, filters, and modulation - Classroom and workshop demonstrations - Playing with drones, beats, and modulated tones Free and Full Version The oscillator, waveform display, filter, modulation, numeric entry, and video export are free. Two-channel operation, preset saving and file sharing, audio file export, and alternate app icons are available through a one-time in-app purchase. Note This app is intended for experiments and quick checks, not precision measurement. Start at a low volume, and take care when connecting earphones, headphones, or external speakers.
