* af_volume: do not change data when volume is 1Gravatar wm42012-01-16
| | | | | | | | | | | When the volume multiplier is 1, the data shouldn't be changed, but the code actually multiplied each sample with 255/256. Change the factor to 256, and hope there wasn't a good reason for the value 255. Additionally, don't work on the data if it wouldn't be changed anyway. This is a micro-optimization. This doesn't touch the code path for the float format.

* Add support for 8 channel audio.Gravatar tack2009-11-10
| | | | | | | | Where 8 channel support is non-trivial (e.g. ao_dsound), at least ensure we fail gracefully. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@29868 b3059339-0415-0410-9bf9-f77b7e298cf2

* 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

| | | | | | | | | | | | | | | | | - 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
