Modular synth effects pedal with dual-range BBD delay and multi-waveform LFO. Users can modulate delay for chorus, flanging, and vibrato. Features adjustable parameters, patchable inputs and outputs, and analog signal processing.
LH Rubbing is a polyphony synthesizer app for iPad. It features three wave oscillators, one noise oscillator, two LFOs, and a three-type embedded filter.
Displays sound waveforms and spectra using Fourier transform. Identifies frequency characteristics and detects peaks. Supports pinch zoom gestures for detailed analysis. Assists in sound adjustment and howling prevention.
Visualize sound frequencies over time with a time-frequency graph. Adjust color intensity to represent sound levels. Use for analyzing vocal tones, animal calls, and identifying household noises.
Udio tones with customizable frequency settings from 15Hz to 22KHz. Choose between sine, square, sawtooth, and triangle waveforms. Create and save custom presets. Control playback from notification drawer, lock screen, or headset buttons.
Create and manipulate sound using two oscillators and one noise generator. Adjust frequencies in Hz or MIDI notes. Apply lowpass filters individually to each . Use panning for spatial effects.
Create and customize using 20 musical scales and 12 key signatures. Adjust 7 octave ranges and use 3-finger controls for playback. Share or save creations. Generate original tracks or follow pre-made examples.
Adjust audio signals with a voltage-controlled and a wide-range LFO. Modulate frequency and depth parameters. Connect to MIDI devices and integrate with modular synthesizer systems.
The app emulates the VCS3, a portable synthesizer created in 1969. It features three oscillators, a noise generator, a voltage-controlled filter, and a unique patch board matrix for component connection.
Tune with real-time pitch display in Hz. Adjust A4 calibration between 415 Hz and 466 Hz. Use tuning fork and advanced settings via in- purchase. LED indicator lights up tuned strings automatically. Supports standard and drop D tunings.
Generate sine, square, sawtooth, and triangle tones across a wide frequency range. Adjust frequency by swiping up or down. Sweep sine frequency for hearing testing. Play tones to clean speakerphone dust and water.
Create and shape sounds with analog-style oscillators and modulation effects. Adjust parameters for deep basses, lush pads, and vibrant leads. Use cross-modulation, PWM, and polyphonic unison for rich tones.
Helps remove from phone speakers using tested frequencies. Users can select free or premium frequency programs to and restore speaker quality. The provides ongoing assistance for maintaining speaker performance.
The app is an experimental virtual-analog synthesizer. It features two oscillators with distortion and feedback, a state-variable filter, and two ADSR envelopes.
Analyze in real time with octave band and FFT plots. Display sound levels in decibels and noise ratings. Choose linear or logarithmic scales. Adjust window functions and track maximum values.
Use advanced frequency cleaning to generate sound waves between 0 Hz and 20 kHz, breaking down particles in speakers. Activate automatic cleaning mode to run a preset session. Monitor progress and manually control cleaning intensity.
