    RF24 audio streaming

    Hi there! I have 2xT3.2+audio shield (16bit 44.1kHz) and 2xRF24 using the RF24 library which works for sending digital messages. My question is how to get the direct 16bit data from the audioshield to put it in the radio.write line for the RF24 transmitter ? And then on the receiver side how...

    Reading Vin voltage directly for external alimentation

    Indeed I see no link to any pin from Vin. Thank you for the information I'll try to connect it then !

    Reading Vin voltage directly for external alimentation

    Hi there! I am supplying my teensy 3.2 with a 9V battery converted to 5V connected to Vin. I was wondering if there is any code I could use to read the voltage directly on Vin ? I assume that I may connect it in parallel to an analog input but I'd like to save it. Many thanks ! YC

    Pitch detection

    Hello there! I'm so glad that there is so much buzzing around this subject with very interesting experiences! My project is to analyze in real time (<10ms latency) a string instrument (lets start with a guitar) signal. I am working with the audio teensy system and have tried the FFT1024 that...

    Predominant frequency identification with FFT

    Paul, thank you the YIN algorithm is really accurate about the frequency ! but I lose the level information I got with the FFT. How could I mesure it so I can associate a frequency with a volume level while using the YIN ?

    Predominant frequency identification with FFT

    Thank you it works now. Another problem was the Audiomemory was set to only 10. I changed it for 30 and now the sine generation works.

    Predominant frequency identification with FFT

    Thank you so much the code now works except for the waveform generation that does pretty much nothing but some "pop" some times. Any ideas? Thank you again Pete.

    Predominant frequency identification with FFT

    HI, All this is based on the FFT tutorial in the audio tutorial of Teensy with its audio shield. I'm trying a simple code in order to identifie in real time the predominant frequency in a complexe sound. In a FOR loop, I compare each FFT value at each 43Hz to get at the end of the loop the...

    audio shield power supply

    Hello, Simple question: I have a Teensy 3.2 and would like to supply my audio shield with it. The teensy is power with usb. I understood that the teensy 3.2 already has a 3v regulator but nothing happens when I check the 3.3v pin of it... How can I supply my audio shield with my teensy 3.2...
