...but Pd cannot open the audio file! :@

<br>- in Audacity: Sample Rate e.g. Format (32-bit float)

Motion Dialogues


Initially influenced by the interest on the current migration flux hitting occident, I will explore physical movement in specific delimited spaces and the reaction/consequences that this physical action will involve. It aims to generate audio feedback loops by using motion and color detection techniques in Pd.

* * Audio Feedback Loop * *



* The loop stops / starts again when new movement is detected inside the square’s area?


1- Webcam + Pd: Square Detects color change / motion


2- Pd: It activates oscilators and generates sound / or plays imported audio file


3- Pd: Sends signal to speakers


4- Speakers: They reproduce Pd audio


5- Microphone: Mic connected to Raspberry Pi, placed near speakers detects the sound (+ surroundings making a mix?)


6- Pd: Live-recording on table (array) with [tabwrite~] just a few sec


7- Pd: Plays automatically after a few seconds with [tabplay~] - - -





Feedback Loop = Score?
