This is just a small CLI program for decoding an SPC file into a WAV file, using Blargg's snes_spc library.
It uses a higher amplification level compared to most SPC decoders,
this can be controlled via CLI with the --amp flag.
The default amplification level is 384, most players/decoders based on snes_spc
default to 256
You can also opt to use the amplification tag found in some SPC files. This is exceedingly rare, and I'll be honest, I'm not sure if it should be honored.
You can also enable ID3 tags with the --id3 switch.
snes_spc and id666 should be available as shared or static libraries.
I have a fork of snes_spc available that incorporates some fixes from the
game-music-emu library, and includes a Makefile suitable for building a
library and installing headers.
Alternatively, here's a small Makefile that can be used with snes_spc version
0.9.0. Unzip snes_spc-0.9.0.zip and place this into a Makefile in the
snes_spc-0.9.0 folder, then run make and make install.
