This video is an update to the earlier SDR video:

In this video I create a new FIR implementation which uses the ESP-DSP
assembler implementation:

The new library is here:

Examples of use can be found here:

Cool! That is what I was hoping for. Do you pin the fir process to a particular core? Then you could use the other core for other things like Bluetooth or UI.

Thanks for all your video's on SDR. It helps me a lot building an SDR. I use a AudioKit with a ESP32A1S and modified your software. Now it is working well but I have a question about . What is happening here? Is it a correction of the amplitude, a correction of the phase or something else?

Is it possible to use lower bit-width and sample-rate like 8 bit and 8000 Hz in phase shifting using internal DAC?
