no, this is in the BruteFIR documentation. BruteFIR
accepts a lot of
input formats, including many binary formats,
uups, my fault -- I thought bruteFIR needs exponents of the FIR filter that
has to be calculated beforehand. But I don't realized that an impulse
response or a recorded sweep can be used directly.
Could you
please send me these scripts. Since I am far more
better in UI design than in algortihmic debugging -- I hope to
make a nice tool from this skripts.
See the attached file. There are two examples for 44.1 Khz & 96 Khz
measurement (shell scripts + BF configuration).
Maybe I am too dumb, but I can't make it work ...
Here is what I have done:
1. create a sweep of 40s with AudioEase's "Make A TestTone 2.0"
(the wav files created with that prog cannot be read by sndfile-convert but
with wavesurfer/snack ...)
2. play the sweep with Spark LE on an iBook through a microverb into ardour
running on my linux box with NVIDIAs onboard sound
3. revert the sweep in time and create a float32 raw file for use with
bruteFIR
4. use bfcfg44 configuration for bruteFIR
but the output is empty (all floats have an exponent of -19..21)
And even the sweep directly fed into bruteFIR gives an empty file.
What do you use
for creating the sweeps?
I used the Aurora plugins from Angelo Farina:

They're not free but they're free enough for my needs :)
But I don't have any windows machine ;-)
