Feature request: Optimized FIR with int32_t (DSP-68)

[Patrik-Berglund]

Hi,

Would be great if you could make an optimized FIR filter for int32_t.

Best Regards

why not just convert into float ?

float bufferConsumer::convert(const unsigned char *src, uint8_t index) {
int i = src[0 + index] << 24 | src[1 + index] << 16 | src[2 + index] << 8;
return i / (float)(INT_MAX - 256);
}

i take my 24bit data and i get directly a float

for example:
0x7FFFFF = +1.0
0x800000 = -1.0
0xC00000 = - 0.5
0x400000 = + 0.5
