Tympan-PC Pipeline
Benesch, D., Raj, K. N., & Voix, J. (2021). A general-purpose pipeline to interface the Tympan hardware with an external computer. The Journal of the Acoustical Society of America, 150(4), A266-A266.
Our project for the Tympan Open Source Audio Processing ASA 2021 Challenge. The slides presented at ASA can be downloaded here.
There are two main components in the pipeline code: - The Arduino code which contains audio elements and USB transmission. - The Python script which receives audio input and sends commands to the Tympan via serial transmission.
The LowPassUSBOutput and the ClapDetectorWhiteNoise folders contain the Tympan code for low pass filtering and clap detection respectively : - LowPassUSBOutput : This code was used to demonstrate USB transmission. The cutoff frequency can be varied using the potentiometer on the Tympan. For more details on the USB audio transmission refer to this page in the wiki. - ClapDetectorWhiteNoise : This code plays white noise when a clap is detected by the Python script running on the external PC.
To test the clap detection script: * Run the ClapDetectorWhiteNoise code on the Tympan. * Open the external_scripts folder, and install the python modules by running pip3 install -r requirements.txt * Now, install the pi-clap module by running pip3 install -e git+https://github.com/danibene/pi-clap#egg=pi_clap * Run the clap.py script (found in the external_scripts folder) * Press c to confirm the default settings (recalibrator is a bit buggy for a chunk size of 1024) and clap away! * If you clap twice, 'm' is sent as the serial command (indicating masking noise toggle) to the Tympan. This should toggle the masking white noise in the audio output.
