# Takes a list of WAV files for the sound effects,
|
||
|
|
# downsamples them to GS-friendly rates,
|
||
|
|
# and packs them into a 64k block that can
|
||
|
|
# be loaded into Ensoniq RAM
|
||
|
|

|

|
|
# IMPORTANT: This depends on sox, which MacOS doesn't have natively.
|

|
|
# You can get it from Homebrew ("brew install sox")
