Hello, thank you for your responses. WMXZ, there is no led activity. Paul, here you will find some much more detailed pictures of the set-up. I asked for some help with the measurements and here are the results. Without connecting the Mic into the Teensy I got; Then, I connected the...

Hi, Im using an EM173 from primo MIC, @94dB or 1 Pascal the Mic is giving me 14 mV, the Sourse impedance is 680 Ohms

I'm developing a soundmeter and i need to construct a pre amp which helps me putting putting one signal from 14 mv to 1050 mv, i already tried with some ops and with transistors, but i need to keep my noise under 700 micro V and the inner noise of my pre amps at the output is around the 10 mv...

Hello, i would like to know how to turn off the MIC BIAS, I'm using an external BIAS for my mic. Thank you.

Hello XXXAJK, i hope you are doing well; i'm having a really ugly SD noise, and i don't know how to solve it with a capacitor, can you help me with that? This is my audio I'm hearing everithing by the HP output and the noise is present when the recording process is on. Thank you.

Working perfectly with the crystal, thank you.

Thank you !!!! Actually the modification that i did was working really bad, thank you again! i'll revise that and then i will come back with good news :D!!!!! So happy !!!

I forgot to say that i modified the DS1307RTC library, initializing with the i2c_t3 library in stead the Wire and replacing all the Wire function with Wire1

Hope this can help https://forum.pjrc.com/threads/34561-How-to-use-the-DS1307RTC-with-the-teensy-audioshield?p=104741#post104741

So if i want to use the first port i need to begin Wire0 and not Wire :p

Hello, i have been struggling a lot with this problem because the real time clock uses the same ports as the audio board for the communication, sda and scl 19-18 in the teensy. i decided to use the ic2_t3 library that allows to use the second SCL-SDA ports (29-30), the problem was that the...
