About

Waveform Camera

Transform images of waveforms into lo-fi audio files. Capture new waveforms or import existing images, then precisely process them into mono or stereo .wav files for use in music projects or DAWs. Experiment with unique sound design possibilities.

Highlights
  • Capture new waveforms with camera
  • Import images from photo library
  • Resizable cropping tool
  • Mono or stereo audio processing
  • Precise sample/second output control
  • Interactive playback with loop handles
  • Export as .wav files

Waveform Camera turns any image of a waveform—whether it's a photo, a screenshot, or a hand-drawn sketch—into a lo-fi audio file for use in any application that can playback or manipulate 44.1kHz / 48kHz audio wav files. CAPTURE & CROP Instantly capture new waveforms using your camera. Import any image directly from your photo library or files app. Use the resizable cropping tool to isolate the exact waveform you want to process. You can re-crop then re-process at any time. Finger paint a waveform in either mono or stereo. PROCESS THE IMAGE Process your image as a mono or stereo audio file. Define the output length down to the exact sample (from 64 to 220,500 samples - or work in seconds, from to 0.001 to 5 seconds). Our two advanced processing engines normalizes the audio and uses interpolation to render a distinctly low fidelity sound from waveform images (and any other image you want to throw at it!). PLAY, PITCH, & EXPORT Your new sound appears on an interactive playback screen with a visual waveform. Drag the start and end handles to select the perfect loop region. Hear your changes in real-time with dynamic loop playback that updates as you move the handles. Detect the pitch (and re-detect from the selected region), fine tune the pitch, or re-pitch to a chosen note and octave with either spectral resampling (maintains the original audio length) or varispeed to re-pitch by changing the length of the audio. Export your final loop or the entire sound as a .wav file, ready to be dropped into any DAW or music project. Add the audio to the chain list, build a chain then export as a single file with cue markers, or equally spaced audio with padding to a fixed value. Export the chain list as a Koala project file (up-to 64 sounds per project) and continue with the samples directly in the Koala app. Perfect for sound designers, electronic musicians, and audio hobbyists. Waveform Camera is the perfect tool for: - Re-synthesizing single-cycle waveforms from your favorite synths. - Turning a drawing of a filter sweep into a real audio effect. - Discovering new sounds in the world around you. Capture, crop, process, and play. A quirky new sound design tool is here to experiment with.

Descent is a real-time granular effect that captures incoming audio, breaks it into tiny grains, and scatters them across time and pitch. The result: everything from subtle thickening and rhythmic delays to vast frozen soundscapes and shimmering pitch-shifted clouds. GRANULAR ENGINE Control up to 50 simultaneous grains with independent settings for duration, overlap, and envelope shape. Play grains forward, reverse, or randomly mixed for tape-style effects, reverse swells, and glitchy textures. PITCH SHIFTING WITH QUANTIZATION Transpose from -24 to +24 semitones. Lock pitch shifts to specific intervals—octaves, fifths, or any chromatic combination—for harmonically correct shimmer and transposition effects. SIX-AXIS RANDOMIZATION Independently randomize pitch, pan, position, amplitude, duration, and grain count. Dial in subtle organic movement or push into complete textural chaos. DIFFUSION AND FEEDBACK High-feedback mode with a diffusion control transforms delays into lush, reverb-like washes that never get harsh or run away from you. TEMPO SYNC Lock grain timing to your session's tempo or let textures evolve freely in untethered mode. 35 FACTORY PRESETS Covering shimmers, delays, reverbs, pitch effects, and experimental sound design. Cross-platform XML presets are compatible across all Audio Damage plugin formats and operating systems. SOUND DESIGN IDEAS Add subtle depth with a few long grains and minimal randomization Create rhythmic delays with short, quantized grains at high feedback Build infinite sustain pads by freezing audio with high grain count and overlap Craft shimmer effects by quantizing pitch to octaves and fifths Transform vocals into ethereal textures with diffusion and wide panning AUv3 compatible. Runs standalone or hosted in AUM, ApeMatrix, Audiobus, Cubasis, GarageBand, and other AUv3 hosts on iOS 13 or newer. From Audio Damage—making creative software for discerning musicians since 2002.
