I have a small device that operates using smartphone audio jack. For the operation of the device I want to send a certain amount of voltage to the audio jack. I'm using AudioTrack in MODE_STREAM I have a buffer which I wrote a sine signal of fixed frequency which have been found.
This audio sends a single voice to the jack. Does this mean that the output voltage is fixed or changes according to the sign signal? Is there a way to ensure that the output voltage of the audio jack is at a fixed value?
Thank you!
would seem to answer my question that AC output control voltage sound volume level And this tool seems dependent. Thanks for the comment!
