Thanks for the info. Appears to be not so simple to cut the 62.5khz block wave on a Teensy. Decided to go for the hardware solution. A simple low-pass filter using a 4k7 resistor and a 15nF capacitor did the trick (image taken from wikipedia). The resulting 2.2khz cut-off frequency effectively...

Thanks for the suggestion. Will try to implement this solution into the current Talkie library. If it doesn't work out, I will try to remove the 62.5khz by using a low-pass audio filter.

I'm trying to switch from 328p to teensy hardware for my APRS tracker with speech. In short, the tracker provides spoken information on position and altitude using the Talkie library. In addition, an APRS message is constructed with the help of a mx614tn modem chip. Both audio message are sent...

I now have the Talkie working nicely on the Teensy 3.2 on pin 5. However, after a voice.say command, how do I get that pin back into a "normal" or inactive state? Using the original Talkie library, I was able to send a voice.end(); command and gave that pin a high impedance by making that pin an...

Yes,including voice.beginPWM(A14); did the trick. I now have clear audio on the DAC pin. Thanks for the quick reply and hellp

I'm trying to get the Talkie library to work with my Teensy 3.2. However, I do not get the audio output on the DAC pin, but on pin 0 RX1! The sound is not great and the use of RX1 also frustrates uploading sketches. I guess the library does not detect my Teensy 3.2 and stills tries to use the...
