I would guess there must be good repositories of C codes for various implementation of filters etc. stream (path, block_length, frame_length, …): Stream audio in. The signal processing blocks written in C++ are connected using python. We use this programming model to transfer computation to the HARP2 platform or to a Xilinx FPGA available in the AWS F1 instances. DFT and DTFT¶.
