Microphones

You can add recording microphones to your task using configurators.Microphone when creating the Neurokraken object.

You can list all microphones currently connected to your computer and their indices with the list_connected_recording_devices() tool.

from neurokraken.tools import list_connected_recording_devices
list_connected_recording_devices()

A microphone can be added to the neurokraken object to create a recording of the task interval. You can also provide a list of microphones to record from multiple sources. After the end of your task you will find the audio file(s) in the log directory.

from neurokraken.configurators import Microphone

mic = Microphone(name='mic', idx=0, sample_rate=44100, num_channels=1)
nk = Neurokraken(..., microphones=mic)

To use a higher end 200khz microphone:

mic = Microphone(name='mic', idx=1, sample_rate=200_000, num_channels=1)

name :str

Microphone name or identifier. The .wav file and log entries will be saved under this name. Defaults to ‘_’.

idx :int

Microphone device index. Your first microphone is 0, the 2nd, 1, etc. Defaults to 0.

sample_rate :int|None

the sample rate to be used, i.e. 44100. At sample_rate=None the microphone’s default sample rate will be used. Defaults to None.

num_channels :int:

The number of channels to be recorded (Mono/Stereo). Defaults to 1.
