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.

reimar 8ee78e87ce always cancel down fractions (frac_t) to avoid overflows and playback
problems (e.g. when using resample and equalizer filters together, see
http://mplayerhq.hu/pipermail/mplayer-users/2004-December/050058.html)

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

anders 66f4e56389 New features:
-- Support for runtime cpu detection
-- Stand alone compile of libaf
-- Unlimited number of channels (compiletime switch)
-- Sample format defined by bit-fields
-- New formats: float, A-Law and mu-law
-- Format conversion set in human readable format
   i.e. format=4:us_be to set 32 bit unsigned big endian output
-- Format reporting in human readable format
-- Volume control has only one parameter for setting the volume
   i.e. volume=-10.0:1:0:1 to set atenuation = -10dB
