In this video tutorial I am sharing some of the methods I have used now and in the past regarding the sampling of audio signals. It shows you three methods:
1. Sequential sampling
2. Interrupt driven sampling
3. I2S (IIS) driven sampling
This is an open source project, all schematics, software and building instructions are available for you. Use it, change is, heck even sell it. It’s ok but if you do one or more of the above, please give me credit by linking back to my channel.
🕮 Software/ firmware / sketch / documentation:
The test program for the I2S method can be downloaded here:

You like me work, please buy me a coffee to help me to burn the midnight oil.

🔀 A thank you goes out to the people who helped me on my quest to find out all about I2S:
Dave Plummer from dave’s garage shared the code of his take on the FFT spectrum analyzer:
Scott Marley shared made a great tutorial about FFT that you can see here:
Atomic14 did a video on how to use I2S and honestly, his was the first good video I found on this topic:
