    I did indeed ask a few questions in this thread. But i can summarize one main question for you if you want: For a DFT/FFT i was assuming a formula like " Σ 0,...,N-1 (output) = Σ 0,...,N-1 (input * e^-i2πkn/N ) "...

    hey guys, be patient with me...but i aswell don't get jack shit out of this FFT1024 algorithm. It's just written in such a blunt style and without any urge at any point to explain what it doest like somebody wanted...

    Hey guys, analyzing the 1024 FFT code from the audio example codes the last couple of weeks I was wondering how high the resolution could possibly be for a fast fourier transformation? Or better: how high does it...

    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...

    Hello dear forum members, i was asking myself earlier today if it is possible to use the wav2sketch.c program "inside" teensyduino? What do I mean with that: Is it possible to use the wav2sketch algorithm WHILE...

    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...
