This is my first question on dsp. I am looking for something very simple here and I am sure there are libraries that will do pitch recognition and FFT but my requirement is very simple.
I have a PC and I am using the audio input for analog signal feedback and output for controlling the device. I am using windows as the OS.
I want to ensure that I have full control on the audio output and no other program or the OS will stream sounds into the same channel.
I want to output precisely at a known time interval
- I want to check if the feedback matches with what is expected of the device.
Any snippet of code or an article to do the same will be useful. I can provide more details if there is something missing in my question.
