* libaf: change filter input/output ratio calculationsGravatar uau2007-11-01
| | | | | | | | | | 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. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@24916 b3059339-0415-0410-9bf9-f77b7e298cf2

* Changes includes:Gravatar anders2002-12-28
| | | | | | | | | | | | | | | | | - 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 git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@8608 b3059339-0415-0410-9bf9-f77b7e298cf2
* the -af delay=[seconds] option currently parses floating point values ofGravatar arpi2002-12-04
| | | | | | | | | "seconds" but uses only the integral part of it. This one-line patch fixes that problem. It should be clear enough. Linards Ticmanis <ticmanis@coli.uni-sb.de> git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@8349 b3059339-0415-0410-9bf9-f77b7e298cf2
* New features:Gravatar anders2002-11-12
| | | | | | | | | | | | | | | | -- 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 git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@8168 b3059339-0415-0410-9bf9-f77b7e298cf2
