floating-point values (-1.0 - +1.0).
So, what is the most efficient way to do the necessary conversion? I'm using
the pyalsaaudio module to access the soundcard, if it matters.

Hello to all. I'm working on writing a tool that will control a piece of
hardware using ioctl's on its device node. Specifically, I'm trying to
configure and tune a DVB-S receiver on Linux.
Just for starters, I want to try opening the frontend and setting the LNB
voltage. An example in C:

A bit more work than I expected, but at least I have an idea what to do now.
I'm working on writing a DVB binding based on the V4L2 binding you mentioned,
currently about 30% complete - I can query the card's status! :)
Thanks for the help so far, might post again if I run into more trouble.

Hello to all. I'm working on a program that will need to do some simple signal
analysis (namely, find the frequency of an audio signal) as part of its
operation.
Something like:
-
samples = list()
for i in range(fft_length):
samples.append(readSoundCard())
fft_bins = FFT(samples, sample_ra
Hello list. I'm trying to put together an AFSK modem in Python, and I have most
of the code worked out. The last remaining issue will be generating the actual
audio signal. Unfortunately, I have never written any kind of audio code before
in any language, so I don't really know what I am doing.
