波動 Hysteric Oscillator vs PolyIvoks Filter

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.

PolyIvoks Filter AUv3 plug-in — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the PolyIvoks Filter AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of PolyIvoks Filter AUv3 plug-in comes as In-App Purchase PolyIvoks Filter developed on the basis of the filter of the legendary Soviet synthesizer from 1980s, and only now the legendary Soviet analog sound became available in stereo mode. Features: • Standalone and AUv3 plug-in; • Precise port of Rack Extensions plug-in; • Modeled vintage Filter; • Undo/Redo; • A/B comparison; • 2x/4x/8x Upsampling; • Macro controllers; • Built-in Gain Match; • Scalable GUI. MODULATOR house the LFO controls: MODE — which offers four waveforms, including Noise and a stepped function for Sample & Hold effects, well as SPEED control. FILTER: The four controls adjust CUTOFF, RESONANCE, LPF to BPF switch, MODULATION (LFO) level and ENVELOPE level (You can set positive or negative values). ENVELOPE: repeating ATTACK/DECAY envelope. MASTER: the rightmost unit has 3 regulators ENVELOPE level (You can set positive or negative values), VOLUME (output gain) and DIGITAL/ANALOG switch. To use PolyIvoks Filter as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — PolyIvoks Filter will appear in the list of Audio Unit extensions for effect plug-ins in the host app.
