PvRecorder Demo for Python

This project contains a Python command-line demo for PvRecorder that demonstrates how to use PvRecorder to record audio to a WAV file.

PvRecorder

PvRecorder is an easy-to-use, cross-platform audio recorder designed for real-time speech audio processing. It allows developers access to an audio device's input stream, broken up into data frames of a given size.

Compatibility

• Python 3.5+
• Runs on Linux (x86_64), macOS (x86_64 and arm64), Windows (x86_64), Raspberry Pi (all variants), NVIDIA Jetson (Nano), and BeagleBone.

Installation

pip3 install pvrecorderdemo

Usage

In the following instructions, we will refer to {AUDIO_DEVICE_INDEX} as the index of the audio device to use, and {OUTPUT_WAV_PATH} as the path to save the audio data in wav format.

{AUDIO_DEVICE_INDEX} defaults to -1 and {OUTPUT_WAV_PATH} can be empty if you wish to not save any data.

To show the available audio devices run:

pv_recorder_demo --show_audio_devices

To run PvRecorder run:

pv_recorder_demo --audio_device_index {AUDIO_DEVICE_INDEX} --output_wav_path {OUTPUT_WAV_PATH}
