Solution: MiniDSP requires 32-bit little-endian float coefficients. Ensure your Python script uses '<f' packing. Also, MiniDSP expects exactly the number of taps defined in the project. Truncate or zero-pad your FRF taps.
with open("firmware.frf", "rb") as f:
data = f.read()
# Remove 128-byte footer, skip first 64 bytes
payload = data[64:-128]
with open("firmware.bin", "wb") as out:
out.write(payload)
frf_to_bin('filters/my_filter.frf', 'output.bin', data_type='float32', endian='little') frf to bin
cp yourfile.frf yourfile.bin
Check if the resulting .bin is usable by your target tool. frf_to_bin('filters/my_filter
