NAME

       SIDPLAYFP - Sidplay is SID-chip emulator for playing Commodore 64 music.

SYNOPSIS

       sidplayfp [ OPTIONS... ] <datafile>

DESCRIPTION

       Sidplayfp  is  a  music player that emulates various components from a Commodore 64 (C64) computer.  The result is a program which can load
       and execute C64 machine code programs which produce music and sound.  Sidplayfp has been designed for accuracy  which  results  in  a  much
       higher  cpu  usage.   Additional  playback  modes have however been provided to allow playback on low specification machines at the cost of
       accuracy, but it still has a higher cpu demand than Sidplay.

SIDPLAYFP OPTIONS

       --help|-h
	      Display help.

       -f<num>
	      Set frequency in Hz (default: 44100).

       -nf    No filter emulation.  This will reduce CPU overhead at the cost of reduced sound quality.

       -ns    Emulate MOS8580 waveforms (default: MOS6581).

       -o<num>
	      Select track number (default: preset).

       -s     Stereo Hardware support.	For Sidplay the channels for the sid will be split into left and right creating a stereo effect.  The same
	      effect  is  present for Sidplayfp unless the tune is identified as stereo.  If this is the case then sid 1 and 2 become the left and
	      right channels respectively.  For Sidplay other options are provided to produce special effects when in stereo mode,  but  Sidplayfp
	      does not as yet support these.

       -v     Verbose output while playing.

       -b<num>
	      Set start time in [mins]:secs format (compatible with sid2wav).

       -fd    Force  dual sid environment.  This forces emulation of  2 sid-chips for stereo playback even if datafile is identified as only being
	      mono.  This occurs in the case of the stereo sid format as currently there is no way to identify them.  Stereo MUS files are however
	      automatically detected.  The second sid appears in the 0xD500 address range.  -fs By default all samples are played through the SIDs
	      master volume.  This can cause the SIDs voices to become disturbed and slightly noisy, but generally  no	worse  than  the  original
	      tune.   This  switch can be used to move the samples to there own channel on the soundcard to avoid this problem.  Note that this is
	      incompatible with some emulations and will cause he samples to be lost e.g. HardSID.

       -m<b|r>
	      Mode switch (default -mr).  Currently supported modes are:
		  Sidplays  Bankswitching Mode (-mb).
		  Sidplay2s Real C64 emulation mode (-mr).

       -p<num>
	      Set bit precision for wav saving. The default is 32 (32 bit float), but can be set to 16 to create 16 bit little endian wavs.

       -o<l|s>
	      Option 'l' will select continuous track looping while 's' will select the current track instead of all.  This option can be combined
	      with the track selection to form -ols<num>.

       -q     Quiet output while playing (opposite of verbose).

       -s<l|r>
	      Playback the left or right stereo channel only.

       -t<num>
	      Set play length in [mins]:secs format (0 is endless).

       -v<n|p>[f]
	      Set  VIC	clock  speed.  'n' is NTSC (America, 60Hz) and 'p' is PAL (Europe, 50Hz).  Providing an 'f' will prevent speed fixing that
	      tries to compensate automatically for the speed difference.  Removing speed speed fixing simulates  what	happens  on  a	real  C64.
	      Options can be written as: -vnf or -vn -vf.

       -r<i|r>[f]
	      Set  resampling  mode.   'i'  is interpolation (less expensive) and 'r' resampling (accurate).  Providing an 'f' will provide faster
	      resampling sacrificing quality.  Fast resampling is available only for reSID emulation.  Options can be written as: -rif or -ri -rf.

       -w[name]|--wav[name]
	      Create WAV-file.	The default output filename is <datafile>[n].wav where [n] is the tune number should there be more than one in the
	      sid.   This allows batch conversion of sid tunes without them overwriting each other.  By providing a name you override this default
	      behavior.  The output file will be <name> with no tune number is added and <name> IS NOT checked for or appended with  a	legal  wav
	      file extension.

       --resid
	      Use Dag Lem's reSID emulation engine.

       --residfp
	      Use Antti Lankila's reSIDfp emulation engine.

       --hardsid
	      Use HardSID device.
