Rudolf Polzer 0fff1380b1 audio: clamp sample values in float->int format conversions 
Make af_format clamp float sample values to the range [-1, 1] before
conversion to integer types. Before any out-of-range values wrapped
around and caused nasty artifacts. This filter is used for all
automatic format conversions; thus any decoder that outputs floats
with possible out-of-range values would have been affected by the bad
conversion if its output needed to be converted to integers for AO.

reimar 33bc71f10d Add support for distinguishing between little- and big-endian SPDIF AC3 
and converting between both.

Both files are not compiled but used as standard headers, so there
is no reason for them not be named like any other header file.

uau 7deec05ea0 libaf: change filter input/output ratio calculations 
Change the audio filters to use a double instead of rationals for the
ratio of output to input size. The rationals could overflow when
calculating the overall ratio of a filter chain and gave no real
advantage compared to doubles.

rfelker 66b1d8c94b finally the dreaded white-noise-with-floats bug is fixed!!!! 
the problem is that lrintf was not prototyped on some systems, but
it's easier and faster just not to use it at all. looks like the cola
goes to our friends the glibc developers for forgetting to put lrintf
in math.h in some versions. :))) i'm sure there are other broken libcs
too though.

also fixed a minor bug in the int->float conversion where the range
for float samples was exceeded...

anders 6adaa78ee9 Changes includes: 
- Improved runtime control system
- 3 New filter panning, compressor/limiter and a noise gate
  - The compressor/limiter and the noise gate are not yet finished
  - The panning filter does combined mixing and channel routing and
    can be used to down-mix from stereo to mono (for example)
- Improvements to volume and channel
  - volume now has a very good soft clipping using sin()
  - channel can handle generic routing of audio data
- Conversion of all filters to handle floating point data
- Cleanup of message printing
- Fix for the sig 11 bug reported by Denes
