Thanks. I just tried with this object, and the code is below: if (peak1.available()) { float monopeak=peak1.read(); Serial.println(monopeak); } The value I get from serial monitor seems like a normalized value? For example if I get 0.24, what is the real value it should be? Thank you.

Thanks for your reply. I think the peak analysis in the audio library does not have a very high resolution? Because it returns 0.0 to 1.0. What I want is the Peak value in millivolts so the peak analysis is not enough powerful I guess.

Thanks. you solved my problem

Thanks for your help, it's really detailed. But I still have one question. If I use the ADC of Audio Adaptor, how can I get the digitalized data of the signal? I didn't find it in the audio library. What I find is an object called "queue" and I think it save the data into an array and I can...

With the operational amplifier I can add an offset to the signal. My connection is : Connect the signal which has the offset to the ADC of teensy. And also connect the signal without any offset to mic input of audio board. The first connection is to do the peak to peak calculation with higher...

The signal fed into the SGTL5000's internal ADC.. Is it possible to get the digital value from the internal ADC? Thanks

Thanks for your reply. To catch the raw data using the audio library, which object I can use? For example if I want to display the raw data in the serial monitor of arduino with a high resolution like the ADC of teensy did, which object I can use? The first step of my project is to get the...

Thank you. I tried to use the operational amplifier to add the offset and it works well. Now I'm just thinking about is there some other ways to get the signal and process it. Thanks for your help!

Hello, I'm using teensy 3.2 with the audio adaptor. The audio signal come into the mic port of audio adaptor, which has the voltage around 0 volt (positive or negative). But the input range of ADC on teensy is 0 to 3.3V which means we can't get the signal when it is negative. Is there some way...

Thanks! I've already solve the problem by another repo you replied: https://forum.pjrc.com/threads/24309-USB-Audio-for-Teensy-3-0/page3 with changing the cores and the boards.txt Thank you.

Hello, I'm using the teensy3.2 and the audio adaptor for it. Thanks to the very powerful audio library, I found the USB function in Audio System Design Tool. In this GUI, they said the example of them are in File > Examples > Audio > HardwareTesting > PassThroughUSB and another example is...
