Provides simple interface for recording audio
Project description
Microphone
Provides a simple interface for configuring and utilizing a microphone in Python.
This package has been tested using Python 3.7, using conda 4.7.5, on both Mac and Windows 10.
Installing pyaudio (required dependency)
conda install pyaudio
Installing this package
Once you have installed the dependencies, clone this repository, navigate to it, and run
pip install -e .
It is important that you use this develop
install option, as the microphone configuration requires that
this package is installed in-place.
Configuring Your Microphone
Now we will configure microphone
to use the appropriate microphone on your computer.
Navigate to Microphone/microphone and run:
python configure_input.py
and follow the selection prompt. This will save your microphone preference for future use. The resulting configuration file will be saved to Microphone/microphone/config.ini
.
The contents of the file will look something like this
[input device]
name = Desktop Microphone (RØDE NT-USB)
index = 1
You can edit this file to change the recording settings (e.g. the sampling rate) used to sampled audio from your microphone.
Testing Your Microphone
Navigate to Microphone and run:
python test_input.py
This should record and play back a brief audio clip using the microphone selected during configuration.
Recording Audio
from microphone import record_audio
# Record 10 seconds of audio
byte_encoded_signal, sampling_rate = record_audio(10)
Playing Audio
from microphone import play_audio
# Play 10 seconds of audio
play_audio(byte_encoded_signal, 10)
