NAME

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

SYNOPSIS

       sidplay  [ OPTIONS... ] <datafile>
       sidplay2 [ OPTIONS... ] <datafile>

DESCRIPTION

       Sidplay  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.  This page covers both Sidplay versions 1 and 2, Sidplay
       being an frame based emulation capable of playback on low  specification PCs.  Sidplay2 on
       the  other  hand  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.

COMMON 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  Sidplay2
              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 Sidplay2 does not as
              yet support these.

       -v     Verbose output while playing.

SIDPLAY2 OPTIONS

       -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).

       -nf<filter>
              New  SID  filter  definition.   This  will redefine ReSIDs internal filter (see the
              sidplay2 homepage for the file format).

       -p<num>
              Set bit precision for samples. The default is 16, but this value will  be  affected
              by the hardware available on the platform you are running.

       -O<num>
              Optimisation  level  (default:  0).  Increasing the optimisation level will improve
              the performance of sidplay2 at the cost  of  accuracy.   The  maximum  optimisation
              level can be found using

       -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.

       -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.

SIDPLAY OPTIONS

       -a     strict PlaySID song compatibility (read the docs!).

       -a2    bank switching mode (overrides -a).

       -16    enable 16-bit sample mixing.

       -ss    enable stereo surround.

       -pc    enable centered auto-panning (stereo only).

       -n     set NTSC clock speed (default: PAL).

       -c     force song speed = clock speed (PAL/NTSC).

       -bn<num>
              set number of audio buffer fragments to use.

       -bs<num>
              set size 2^<num> of audio buffer fragments.

       -b<num>
              set sample buffer size.
