Using FPGA's for audio processing - jaeblog jaeblog
https://justanotherelectronicsblog.com/?p=402
The job of the FPGA here is to sample in the data, output a 24 bit word for left and right audio data and a signal that there is data available. To output data the inverse is needed, some logic that takes a 24 bit word for left and right audio data and a signal saying the data can be send out. The code to sample in data is the I2S_Decoder.vhd file.

016 - Floating-Point Audio Processing with FPGAs. Oct 25. Written By Isaac Verdu. In this post we will take our first steps into the world of floating-point audio processing with FPGAs by converting our fixed-point audio samples to floating point and performing a basic delay operation. Most processing in FPGA designs is done using fixed-point number representation, …
