Record Audio

Vivid Unit has two on board microphones and it can be used for audio streaming or recording.

In the application menu, under the “Multimedia” category, you can find “Sound Recorder”.

Just click the blue “Record” button to start the recording:

To stop the recording, you just need to click the red button. You can then save this recording with specified name, and even export the audio file.

If you find the volume of the recorded .wav file is rather low, you may use the sox tool (already pre-installed in the system) to increase its valume:

sox -v 5 old.wav new.wav

The example above increase the volume of old.wav file and save it as the new.wav file (the old.wav file itself remains unchanged).
