Thanks a lot Pete, I'll try to install the buttons and analyze the FFTs of the other Signals! I'm not sure about that, because with && the value f0_new would need to be 5Hz higher than f0_old and 5 Hz lower than...

Thanks for your answer manicksan! The AudioPlaySdWav::consume(uint32_t size) function could really probably work, but i somehow can't really find the encoder segment? I thought it should look like the wav2sketch...

Guten Tag Frank, i want to write a discrete fourier transformation in teensyduino. The idea is to send discrete values of an audio signal into that function, so i need to sample the .WAV file which I'm recording. But...

Yes exactly, there isn't really one unique recording of your voice which will always sound the same - there will be filtering-effects due to different recording sessions. I thought of something like a "frequency...

Thanks for the advice, i will try that out! Did you ever connect a microphone to one of your teensys / audio boards? Would be interested if you got any tips for a good little MIC and what to bear in mind when connecting...

Hello dear defragster / dear forum members, I have a few questions regarding the FFT Example: Above you said that audio input needs to be connected to pin 16...so does that mean that if I'm connecting a device...

Guten Morgen Frank, i thought of using this device for example for my phone as an authentification. With a FFT of my voice I should get a pretty unique fundamental with a overtone series. I think it could work...
