Ah, alright! I did not realise that during compilation I have to set the USB type in the IDE. Now, I can stream the output of my SDR onto my computer. Thank you WMXZ and Paul!

Hi, On my fresh install of Arduino 1.8.5 and TeensyDuino 1.42 the compiler tells me that AudioOutputUSB does not name a type. I am on Mac OSX. Has it been removed from the TeensyDuino on OSX because of the USB audio problems? Compilation of the example program WavFilePlayerUSB gives the same...

Hi, On the power supply lines of my Teensy 3.6 I noticed a strong switching noise which is related to the sampling frequency of the attached audio shield. There are a lot of peaks in the spectrum of the power supply lines. The lines in the spectrum are harmonics, a distance of (samplingrate /...

Hi, I just uploaded to GitHub a library which allows a user to display, select and change settings in a program. Selecting and changing can be done by button presses or a rotary encoder. To get an idea, here are some shots of my current project using the library. The first is of the normal...

Hi, I just uploaded my new library for switching (on and off) in audio streams. It lets the user / program change routes through the audio blocks. The library is at https://github.com/kvdijken/AudioPlugs From the readme file: This library lets the user create switches in the audio path. These...

No, unfortunately I do not have a video of my SDR running. Thanks for sharing your code. I will study it. But as the original Python sources encompass all type of filters (LP, HP, BP, notch, ...), I will translate that code into C when there is a need. This is not so difficult now the...

I have included some example code in README.md

Library for calculation of FIR coefficients Those who use FIR filters may be interested in a very early version of a library to calculate FIR coefficients which I created. It is a translation of the firwin Python code in the scipy library. Scipy does a fantastic job at calculating these...

Regarding what components behave different when setting another sample rate this way, the sine generator was mentioned earlier. Also the AudioEffectDelay behaves different, because it uses AUDIO_SAMPLE_RATE_EXACT in its code. Koen

Thanks, that is clear. Anything on the Teensy between input and output in the audio library objects. Thank you

Hi Forum, I have a question regarding the AudioProcessorUsage() function. Is this measuring the cpu usage of the Teensy or the cpu usage (if applicable) of the audioshield? Greetz, Koen
