Audio technology projects by Atharva BankarBuilding new tools for sound.

Foley artists perform sounds like footsteps and cloth movement in sync with picture. Gesture Foley brings that performance to a webcam. An AI hand tracker follows your fingers, and touching your thumb to a fingertip plays a sound, so you can perform a whole foley pass in front of your screen without a pit full of props.

It runs in the browser with no install, or as a Python app that sends every touch as MIDI into a DAW like Reaper, where the performance can be edited like any foley recording. Ten sound folders, from footsteps, cloth and props to jewellery, creatures and cinematic hits, hold 143 sub-categories such as Wood › Stairs or Leather › Jacket, and you can drop your own recorded samples into any of them.

• Precise by design. Fingertips are smoothed with a One Euro filter, each touch plays once, and only the clearly closest finger can fire, so two sounds never trigger together.
• Blend pad. Each folder has an XY pad with a surface in every corner. Move the point, or steer it with your palm, and each hit mixes the four at an even loudness.
• Layer pad. A second pad plays with every hit from any folder: cloth under footsteps, keys and chains under horses, whooshes under cinematic hits.
• Size, mixer and templates. Size changes the character's weight, a mixer sets level, pan, mute, solo and room, and 22 templates such as Forest walk, Bar fight or Storm set it all in one click.
• Expressive. How fast your fingers close sets the velocity: a quick touch is a hard, running step.
• Next step. A JUCE plugin (VST3/AU) for Pro Tools and Reaper, with a recorded sample library.

NotchWave turns the MacBook notch into a living part of the interface. At rest the notch looks normal. When sound plays, it widens on a spring and frosted-glass waveforms rise out either side, then it settles back about 1.6 seconds after the sound stops. The aim was for it to feel like a feature Apple could have shipped.

It listens to the microphone, everything the Mac is playing, or a single app. Bass sits next to the notch and treble reaches out to the tips, mirrored left and right: the same frequency layout as the vinyl visualiser, unrolled along the menu bar.

• Five shapes. Wrap, Wave, Bars, Thread and Dots, in Glass, Aurora or System Accent colours.
• Private by design. Audio is analysed in memory and discarded. Nothing is recorded or sent anywhere.
• Fits every notch. The size is read from macOS, and displays without a notch get a virtual one while audio plays.

The Vinyl Audio Visualizer draws music as a landscape on a turning record. Each moment's spectrum is cut into the vinyl under the needle, and the spinning record carries that history round, so tall peaks rise from the surface and travel with it. Ninety-six grooves run from 30 Hz at the label to 16 kHz at the rim. With no sound, the grooves stay flat.

It started as a Max/MSP and Jitter patch at university, inspired by the video for The Oracle, a theme by A. R. Rahman. The website rebuilds it for anyone to use: a full 3D turntable with a graphite base, metal platter and tonearm, wrapped in a frosted-glass interface.

• Three sources. The microphone, your own tracks (drop files to make a queue), or audio from a browser tab or the whole computer.
• Like a real deck. Hold, 16⅔, 33⅓, 45 and 78 rpm, wave height and zoom, and drag to rotate the turntable.
• Now Playing. An Apple Music-style bar with album art and track details read from MP3, FLAC and M4A files.
