Intended for use on a Raspberry Pi (Development and testing using a Raspberry Pi 3 Model B)
Full documentation on the Seeedstudio wiki: https://wiki.seeedstudio.com/ReSpeaker_Mic_Array_v2.0/
This implementation is a more bare bones version of the code provided by the supplier. The relevant steps include:
- Configuration of 6 channel firmware
- Configuration of Direction of Arrival (DOA)
Development and testing using Python verison: 2.7.16
pip install -r requirements.txt
Runs all of the scripts in the correct order.
sudo python run.py
Selects an audio files from the pool of available audio files as configured by the user. If species and/or calltype are not specified then the script will randomly select one. Plays the selected audio file
Generates audio and DOA filenames given location, calltype, date and time info Records for audio for 60 seconds and DOA information. Stores files using filenames generated by filename()
Upload the audio recording to the Cacophony server using the API documentated here: https://api.cacophony.org.nz/ Upload the DOA info by storing it as 'additionalMetaData'
Useful for testing. Currently configured to spin when selecting and playing audio lure and display DOA when recording. This should be tured off in the field by running:
from led import spin, listen, on, off
off()- Make sure you check the index of the device. The device index could be different between devices and may need to be changed.
- Install the correct firmware onto the device using the DFU.py script using --download 6_channels_firmware.bin
