Thanks @Paul, for always helping me understand everything from spam bots to serial protocols. I think I was trying to understand if the 0 to 1.0 output range corresponded to any known maximum voltage on the mic input. In the same way that on a 3.3v microcontroller input pin, the range of...

Hi Kidestuarine, thanks for the response. I am using the Teensy audio processing library. With any normalisation, you need to know what the maximum and minimum values are that are to be scaled between 0 and 1.0. That is where I am getting confused. I understand RMS values but am having...

Hi, I am looking for some clarity about the AudioAnalyzeRMS function. I am applying it to the mic input and getting fine results but I am curious about what 1.0 scales to in this case. Is the maximum of the normalised value floating or is it set some where? I have set the micGain to the 36dB...

I posted a specific help question yesterday. But it brought up a broader range of questions that I have had using the audio shield and a touchscreen. To be clear - I have had success with a specific set of pin connections and the Teensy 4.0. I have read the PJRC ILI9341 documentation and the...

Hi Mark, My PCB definitely does not include the ability to change the pins but these pin allocations were working great in my last pcb with the 4.0. Is there a reason that D/C would need to be on pin 3 for 4.0? I have always found the table on the link you shared confusing because it...

Thanks, Kurt. I think that in the example code for the XPT2046_Touchscreen.h library, there is an orientation for both the touch and the screen. The values of where it is being "touched" change correspondingly for me. I will run your code but I think what I was getting at was that the place...

Hello, I have made a new PCB board for a project that I am working on that uses both the Audio shield and the touchscreen sold by PJRC. In this newest version, I have used a 4.0 instead of a 4.1 while keeping the same pin routing as with the 4.0. The code for that routing can be found below...

Hi Paul, Thank you for your response. It made me try my code again and I was able to locate another error that was actually causing the change to not work. I really appreciate your help. I am sure you get tired of dumb questions but your answers are really helpful. Sasha

Hi MarkT, Do you mean notefreq() which is part of the Audio.h library? If so, this is the description, "Detect with fairly good accuracy the fundamental frequency fo of musical notes, such as electric guitar and bass." That works well if I am looking for the fundamental note but I am trying...

Hello, I have the tone function working very well in my Teensy code - thank you for making such a useful object! Now I want to be able to adjust what tone I am detecting using the tone function and it seems like I can only set the frequency that each tone object looks at in the setup function...

The other 2 items in your code that would be very useful for the group that I am working with are the time stamps and the wav file recording instead of raw files. If they can just grab the SD card after an event, that would be wonderful. It will not be audio engineers who want to parse through...

It might be that I should go back and begin from the audio/examples/Recorder which is more at my level of coding. I came to microSoundRecorder because: 1) it was reported as being very robust and even though what I am doing is very simple, that robustness is useful for interactive...

1) You wrote: The above should not happen, how did you install Arduino, TD on which OS? It is installed on Mac OS 10.14.6. Arduino and Teensyduino in their current setup have been on this OS and machine for about 6 months without problem. I am happy to change OSs though. 2) I am sorry for...

Thank you for your help with this. I have a couple more questions 1) I am getting the following error when I try to compile the code as you suggested above. I did this with a fresh download of the microsoundRecorder folder without any modifications to the config.h file just to make sure that...

Hello, Thank you for your response. I had to put this project on hold for a couple of weeks but I am back at it. I am trying to use the AUDIO_INPUT_MIC on the Teensy audio board to record a sound file when a high signal is received on one of the Teensy digital pins. I initially missed the...

Thank you for your fast reply. That makes a lot of sense and is similar to the kind of coding that I have seen with real-time audio coding. I have never seen that done with Arduino/Teensy. It also makes a lot of the other forum questions and responses make more sense. Thanks a lot.

I am trying to learn how to use WMXZ's microSoundRecorder code and I am very confused about how to use this code. In general, I understand including header files for libraries in my Teensy code but this seems different. Are there any example files available? I have read through the wiki and...

Help finding that documentation Hi MarkT, Is there any chance that you could provide a link to the "AudioControlSGTL5000 documentation" that you are talking about? Is that different from https://www.pjrc.com/teensy/SGTL5000.pdf? I am having trouble parsing out some of the audio connections...
