       sidplayfp - a C64 and SID chip emulator for playing Commodore 64 music.


       sidplayfp [OPTIONS] datafile


       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 quite high cpu usage.  Additional playback modes have however been provided to allow
       playback on low specification machines at the cost of accuracy.


       -h, --help
           Display help.

           Set audio output frequency in Hz (default: 48000).

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

           Select track number (default: preset).

       -s  Stereo playback.  If the tune is identified as stereo then sid 1 and 2 become the left
           and right channels respectively.

           Verbose output while playing.

           Set start time in [mins:]secs format (compatible with sid2wav).

           Force dual sid environment by adding a second chip at specified address.  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 prg format as currently there is no
           way to identify them.  Stereo MUS and SID files are however automatically detected.
           The second sid may be installed in the 0xD420-0xD7FF or 0xDE00-0xDFFF address range.
           Address may  be specified in exadecimal (e.g -ds0xd420) or decimal (e.g.  -ds54304)

           Add a third chip at specified address.  The sid may be installed in the 0xD420-0xD7FF
           or 0xDE00-0xDFFF address range.  Address may  be specified in exadecimal (e.g
           -ts0xd440) or decimal (e.g.  -ts54336) format.

           Mute a channel.  May be used more than one time.  Channel 1 to 3 are for the first SID
           chip while channels from 4 to 6 are for the second one and 7 to 9 for the third.

           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. Other values will cause invalid output.

           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

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

           Set play length in [mins:]secs format (0 is endless).

           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 fixing simulates what happens on a real C64.
           Options can be written as: -vnf or -vn -vf.

           Set SID chip model.  'o' is the old 6581 and 'n' is the new 8580.  Providing an 'f'
           will force the selected model overriding the one specified by the tune.

           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, --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 it is possible to
           override this default behavior.  The output file will be <name> with no tune number
           added and <name> IS NOT checked for or appended with a legal wav file extension.

           Use VICE's original reSID emulation engine.

           Use reSIDfp emulation engine.

           Use HardSID device.

Key bindings

       1-9 Mute/unmute voice.

       f   Toggle filter.

       p   Pause/unpause playback.

       Esc Quit player.

       Up/Down Arrows
           Increase/reset playback speed.

       Left/Right Arrows
           Move to previous/next subtune.

       Home/End Arrows
           Go to first/last subtune.


           The path to the HVSC base directory. If specified the songlength DB will be loaded
           from here and relative SID tune paths are accepted.
