2.1.5 Audio
Basic Specifications
WAV playback, voice recording and playback are supported.
By using the Microsoft
SoftwareMixer
function, output sounds from multiple applications can
be mixed and output (in 44.1 KHz, 16-bit stereo mixing).
Voice Recorder is integrated in the terminal as the sound system application to make it possible to
perform WAV file streaming playback and local file playback in HTTP.
Audio and Buzzer use the same integrated speaker, therefore it is not possible to playback Audio
and Buzzer sound at the same time. In this case, Buzzer sound has the priority.
