Audio Software for Raspberry Pi Speech Development Kit

*Note: This software only runs on the Andrea PureAudio™ USB sound card.

The audio software simplifies adding clean audio to any application on the Raspberry Pi.
This is achieved by providing two components:
The first component is an audio filter library, which provides the following functionality:
Handles capturing the microphone input from the USB device.
Handles sending the audio to be played out the USB device.
Filters the input audio with beam forming, noise reduction and acoustic echo cancellation to provide clean audio in noisy environments.
Provides trigger word and command detection, including barge-in when audio is playing out the speakers.
Optionally, provides the filtered input audio buffers to the main application.

The second component is a sample application that demonstrates how to use the simple interface to the audio filter library. This application listens for the trigger while playing audio out the speakers. When the trigger is detected, the volume of the audio playing out the speakers is reduced, and it makes a short WAV audio recording.

Click the button below to download the Beam forming noise reduction filter software along with the voice trigger phrase “Hello Blue Genie” that enables your Raspberry Pi to be controlled by far field voice commands.
