About the project

• Interactive DEMO:
  • Cloud Instrument raspicultor + custom controller version video. Interactive demo retrieving sounds from the Cloud using MIR descriptors and processing them in realtime (using raspicultor aka raspberry pi + apicultor).
  • Experimental session with sounds from the cloud. First live demo with an standard midi controller.
• Embedded instrument running in a Bela or Raspberry Pi: cloudpicultor.
• Cloud Instrument mention in ArCiTec prize, Technology applied to Arts (2018).
• Publication: Sound recycling from public databases @ Audio Mostly 2017
• "Forgotten pieces from unknown people" and "Dialectic in suspense" constructed using APICultor, were showed in NIPS 2017 Art Gallery (Machine Learning for Creativity and Design, Long Beach, California, USA)
• "Sound recycling from public databases" was presented at Technarte Los Angeles 2017.
• Recycled sounds: Sound miniatures

APICultor born to realize interdisciplinary performances based on sounds of the web platform http://redpanal.org. The system is also useful to use with any other sound database on the internet or even running it locally.

The sound is processed digitally using different live-coding techniques. A pre-analysis based on Music Information Retrieval (MIR) stored in a database and accessed via a web-service REST API is combined with real-time processing and synthesis, random processes and human control via external interfaces.

Examples available with SuperCollider, Pyo and pure data.

News

• 2018
  • Migration to Python3 and setup.py install thanks to MarsCrop!
  • MusicEmotionMachine by MarsCrop (in development)
  • Cloud Instrument ready to play with an external controller, running in a dedicated device like Raspberry Pi or Bela Platform
• 2017:
  • SuperCollider patch to play in realtime using sounds from public repositories (databases on the web). Realtime synthesis, wav retrieving using MIR descriptors, OSC & MIDI communication between process and controllers.
• 2016: First demos (extracting MIR features, database build, MIR State Machine, etc)

Performances

Sonidos Mutantes

Interdisciplinary performances based on sounds of the web platform Redpanal.org

Proofs of concept:

• APICultor + No Input + Granular synthesis live performance.

• Compositions & recycled samples

  • API-Cultor compositions
  • Proyecto de reciclado de sonidos libres de la web en RedPanal.org (sonido + referencia al original).

• Generative music using MIR state machine a free/libre sounds from Freesound.org:

  • "Feature Thinking" (with Creative Commons sounds from Freesound.org) by hordia.
  • State Machine @ CASo (Centro de Arte Sonoro) https://www.youtube.com/watch?v=sG1YUc8PQV4

• Live performances using this tool:

  • Jam con guitarras + fx chain y sintes analógicos: Perfo mutante en La Siesta del Fauno
  • Closing performance of the Workshop of Experimental Sound: http://redpanal.org/a/banda-de-mutantes-cierre-taller/
  • La Noche de los Museos La Casa del Bicentenario: Performance 29/10/2016 Con visuales 3D (Blender game engine) ) Reseña: enjambrebit-y-la-banda-de-mutantes/

• "Remixes que toman audios libres de RedPanal.org para categorizarlos según diferentes tipos de emociones. Luego se elige una y se sincronizan las pistas, cambiando las tonalidades. De ser posible se separan de fuentes dentro de las mismas" (by Mars Crop)

  • Beats intro jazz
  • [Bass & DJ] (http://redpanal.org/a/sm-bass-guitar-plays-with-dj/)

Components

• Mock web service with API REST to provide audio samples using MIR descriptors as parameters
• State machine, with each state defined by several MIR descriptors.
• Interaction with the free internet sound database http://redpanal.org
• API REST
• Webscrapping by tag
• Algorithms MIR to extract mean values or by frame of audio samples
• Segmentation algorithms using different criteria.
• Classify algorithms and clustering of samples of the sound database
• Server OSC
• Examples in Supercollider, pyo
• Examples with MIDI and OSC controller. Locale and remote.

Dependencies

Tested under Linux, Mac OS (>10.11) and Windows 10.
