Is there a partitioned convolution project working at 24bits instead of 16 or how may I modify the current 16 bits project ?

Thanks
 
The IR isn't a problem, it' sufficient to scale it to 16 bit, even if we get less resolution...what I need is to modify the 16bit convolution FW to a 24bit, the I2S and the DMA work with a 16bit resolution (wire, audiomod,...libraries)
 
Note that the DD4WH code is float32, it's just fed by 16 bit audio samples.


Thank you Jonr,

I've modify the DD4W FW code (convolution) to work with 32bit data but the libraries (data structures, DMA,...) work with 16bit data; are there different libraries working at 32 bit resolution ?
What I need is to program the DMA and the I2S interface to interface a 24bit codec WM8960) with the Teensy4.0 board using 32bit data structures.
