echo~echo | êkhos vs Audio Object

êkhos is a stereoscopic audiovisual work you hold in your hands — a single, slowly turning orb of granular noise, suspended in black and rendered in 3D. On iPhone, iPad and Mac it plays in anaglyph 3D: classic red-cyan stereoscopy. Put on a pair of red-cyan glasses and the orb lifts off the screen into real depth — strands of light drifting toward you and away, the echo made dimensional. THE WORK êkhos takes its name from the ancient Greek word for resonance — the echo as a thing in itself, rather than an effect. The title, )))echo~echo(((, also reads as noizu — ノイズ, Japanese for noise. The piece sits exactly there: between the echo and the noise, between a sound and the residue it leaves behind. THE DUO êkhos is the work of Mariusz Szypura and Paweł Krawczyk — a long-running guitar and ambient duo. Their music is built from prepared guitars, granular textures, field recordings and slow-moving harmonic clouds: long-form pieces that drift rather than progress. Here that sound is paired with stereoscopic image, so depth itself becomes part of the composition. THE INSTALLATION êkhos was presented at Lincoln Center during Unsound Festival NYC, 2024, as an anaglyph stereoscopy A/V installation. This app brings that installation home: the same prepared-guitar drones and the same drifting visual depth, now on your own screen. HOW TO WATCH • Bring red-cyan (anaglyph) 3D glasses — the inexpensive cardboard kind work perfectly. • Find a dark room and turn the volume up; the piece lives in low light and long duration. • Tap to play. The controls fade away and leave you with the orb. TUNE THE DEPTH TO YOUR EYES The player decomposes the stereoscopic image live, so you can shape the 3D to your own eyes and glasses while the film plays: • DEPTH — shifts the stereo convergence plane in real time: pull the orb out in front of the screen, or push it back behind it. • TINT — calibrates the red-cyan balance to your particular pair of glasses, for a clean, ghost-free image. • 3D / 2D — no glasses at hand? Switch to 2D and watch the film as a flat, luminous monochrome sphere. PRIVATE BY DESIGN No account. No sign-in. No analytics. No tracking. No ads. The film is bundled inside the app and plays fully offline. êkhos is also available on Apple Vision Pro as a true Spatial Video, with real stereoscopic depth and no glasses required. On every screen it is the same idea: an echo you can step inside. Released on Black Element Label.

Audio Object is a pocket-sized music instrument for iPhone. It looks and works like a small piece of hardware — a wooden body with an instrument panel on each face. Pull the wood edge and the body rotates to the next face. WHAT IT DOES - Four-track looper with bar-quantized recording and per-loop trim - Three-voice drum machine as the click track — kick, snare, hi-hat with a per-step accent grid - Eight-pad sampler with grid, auto, and tap chopping, two switchable banks, three-band EQ, varispeed tuning - Project save, load, and WAV stem export with tempo map - Streams audio to any Mac DAW over USB (Inter-Device Audio & MIDI) - Sends MIDI clock over USB — Ableton, Logic, and Bitwig lock transport to the phone - Records stereo from any Core Audio interface (iRig, Focusrite, MOTU, and others) HOW IT WORKS Six faces. Perform pads on one, sampler on another, click and time signature on a third, projects on the back, I/O on top, master on the bottom. No menus, no tabs. Every control lives on the body. The click track is not a metronome. It is a three-voice drum machine with per-step accents, subdivisions from quarter notes to swing, and time signatures from 3/4 to 12/8. Set up a kick-snare-hat pattern, press record, loop on the beat. The sampler holds eight pads across two banks. Record from the mic or load from Files. Chop by grid, by transient, or by tapping markers. Each pad carries a three-band EQ, varispeed pitch, and an amplitude envelope. All eight play polyphonically. Recording quantizes to the bar, the beat, or runs free. A dedicated loop-adjust face trims each loop to the sample — drag the region brackets, snap to the grid, hear the result while the brackets move. Plug the phone into a Mac over USB. Audio Object appears as an audio input and MIDI clock source. The DAW locks transport to the phone's tempo. No drivers, no setup. Plug a USB audio interface into the phone. Audio Object names the device on screen and records through its preamps at up to 48 kHz stereo. WHAT IS NEXT A synthesizer — bass, chord, and lead modes — is in development for the next major release.
