Sticky Revision: |
* new filter implementation, which is more accurate and supports all filter types including bandreject and lowpass turbo
* Filter tuning: calculation of cutoff frequency and bandwidth improved. Removed use of "BasicBPFilter". Changed bandpass filter from constant peak to constant skirt. Use gig parameter Resonance if no resonance controller is set. Removed keyboard tracking influence on resonance.
* gcc 4.0 compilation fixes
* hand-crafted assembly optimization code can be disabled with './configure --disable-asm' (definitely not recommended)
* All compile time options are now centrally alterable as arguments to the ./configure script. All options are C Macros beginning with CONFIG_ prefix and will be placed into auto generated config.h file.
fixed libgig include rules
* some fixes regarding the filter (fixes the "silence" bug which occured occasionally, caused by random biquad parameters which lead to unstable filter equation and thus to infinit filter output results)
* architecture independence fixes, should now compile again for non x86 systems * tiny fix of command line switch --version
* introduced 'synthesis mode' to reduce the amount of code and conditionals for the current synthesis case in the main synthesis loop * support for MMX and SSE(1) in the core synthesis algorithms (CPU feature detection at runtime, only x86 so far)
* biquad filter parameters are now calculated outside the interpolate loop for better performance * couple of loop unroll optimizations * filter is now enabled by default * cubic interpolation is now enabled by default * reduced debug level to 1 to lower verbosity * raised default limit for voices to 128 * raised default limit for streams to 150 * added some compiler optimization flags (-ffast-math -march -mcpu)
updated copyright header for 2004
* completely restructured source tree * implemented multi channel support * implemented instrument manager, which controls sharing of instruments between multiple sampler engines / sampler channels * created abstract classes 'AudioOutputDevice' and 'MidiInputDevice' for convenient implementation of further audio output driver and MIDI input driver for LinuxSampler * implemented following LSCP commands: 'SET CHANNEL MIDI INPUT TYPE', 'LOAD ENGINE', 'GET CHANNELS', 'ADD CHANNEL', 'REMOVE CHANNEL', 'SET CHANNEL AUDIO OUTPUT TYPE' * temporarily removed all command line options * LSCP server is now launched by default
