Hi to every body,
I´m trying to take measurements of audio with a microphone conected to a microcontroller with DSP.
Untill now I think that the audio measurements use to made in AC voltage, measuring peak to peak on Veff voltage. But in mi project mi ADC are measuring in direc voltage and ofcourse only the positive part of the signal.
Any ideas about the tipe of conditioning of the signal??
Many thanks
