This piece gets inspiration from Alvin Lucier’s Sferics (1988). Sferics musically explored electromagnetism from radio waves in the ionosphere. In this piece, I investigate the acoustic properties of electromagnetic fields and their translation into music. I am using MIRLC 2.0, a self-built library in the free Supercollider software. I am developing this library to allow the live coder to retrieve or rewire sounds based on music information retrieval techniques. You can find the first version at github.com/axambo/MIRLC.

The audio input signal is a personal recording of electromagnetic fields emitted by a home network router recorded with a self-built induction microphone. You can find out more about circuit sniffing in this video by Nicolas Collins: https://youtu.be/4T7qkYY7LZM. Based on these acoustic properties of the pitch, onsets and beats, a sinusoidal sound generator, a bit crush sound effect, and a bass generator are triggered, respectively.

This piece was first released in the album compilation Compassion Through Algorithms Vol. II (Light Entries, 2020), a collaboration between Light Entries and Algorave Sheffield curated by Alex McLean, with all proceeds to Young Minds Together: https://lightentries.bandcamp.com/album/compassion-through-algorithms-vol-ii

It has been presented live for the first time at “Concert PACE 1 Live Music from MTI2. Works by Simon Emmerson, Anna Xambó Sedó, John Richards, and Leigh Landy” on November 10, 2021, during the Electroacoustic Music Studies conference 2021 in Leicester: http://www.ems-network.org/ems21/schedule.html 

This recording is a rehearsal previous to the EMS21 Concert: Live Music from MTI2 and it is dedicated to Alvin Lucier, who has passed away on December 1, 2021.

Magnets @ EMS 2021 Rehearsal - To Alvin Lucier

The performance consists of a live coding session using the self-built SuperCollider extensions MIRLCa, MIRLCRep2 and MIRLCRew2 and a DIY box. 

The session presents a new seasonal site-specific piece, *4 boxes*. The piece combines personal sound samples with crowdsourced sound samples from Freesound that are manipulated in a live coding fashion combined with live sound from a physical black wooden box.

This piece has been premiered at the concert "Performing Critical AI I: feedback, noise, corpus, code", MusAI conference, Cafe OTO, London, UK. November 27, 2022.

4 boxes @ Cafe OTO Rehearsal (27.11.2022)

Audience participation performances are a recurrent theme in the Web Audio community and can take as many shapes as imaginable. Berlin, the city hosting the Web Audio conference this year, has been a source of inspiration for innumerable artists, both known and unknown. This performance is an anonymous celebration of participatory music in Berlin in the form of a collective soundscape. Inspired by John Cage’s Imaginary Landscape No. 4 (1951), twelve audio streams from the Berlin area are sonically distributed, repeated, delayed, amplified, reverberated, distorted and finally vanished.

Live Coding / Dokkhuset - Trondheim, Norway (24.11.2018)

**Live Coding with Crowdsourced Sounds & A Drum Machine**

The access to crowdsourced digital sound content is becoming a valuable resource for music creation and particularly music performance. However, finding and retrieving relevant sounds in performance leads to challenges, such as finding suitable sounds in real time and using them in a meaningful musical way. These challenges can be approached using music information retrieval (MIR) techniques. In this session, the self-built system MIRLC (Music Information Retrieval Live Coding), a SuperCollider extension, will be used to access audio content from the online Creative Commons (CC) sound database Freesound. The use of high-level MIR methods is possible (e.g., query by pitch or rhythmic cues). This live audio stream of soundscapes from crowdsourced audio material will be combined with a vintage Roland MC-09 used as a drum machine.

Live Coding / ICLC2019 - Madrid, Spain (19.01.2019)

This piece is a remix of the sonic piece "Kicks" (https://soundcloud.com/annaxambo/kicks), and explores the original source within the self-built live coding environment MIRLC (https://github.com/axambo/MIRLC). The rhythm of the source is repeated creating slight out of phases, the rhythmic audio features of the audio source determine the shape of overlaid noisy beeps, and related glitchy sounds from Freesound.org are combined to the textural sound mass.

Kicks & Cuts

This piece explores the granular texture of footsteps on leaves with the  the plugin AudioTexture (Le Sound) using Reaper. It has been built upon the sound "01-20 Footsteps, sneakers on dry leaves" by SpliceSound from Freesound.

Footsteps

This example showcases the possibilities of the plugin SampleSurfer (Waves Audio LTD) by selecting sounds from the online databases of Freesound and Jamendo under certain criteria (particularly C minor) and creating a musical piece by adding effects with Ableton Live.

**A situated live coding session**

A situated recording of a situated live coding session where crowdsourced sounds from the Internet are retrieved, transformed and dissipated using a self-built live coding system. The performance starts with a blank canvas and the situation will help to shape the sound corpus. The tools used include the self-built SuperCollider live coding environment MIRLC, metal springs and a DIY contact mic.

Anna Xambó is an experimental electronic music producer. Biased for being passionate about extreme digital minimalism and a past performer on bass guitar, she likes to explore the boundaries of digital sound focusing on low frequencies, compulsive rhythms, and noisy textures. Some of her works have been published under the alias peterMann through the experimental electronic music label Carpal Tunnel, which she has co-founded. Her latest solo recording is “H2RI” (pan y rosas, 2018).
