New to the programs, I downloaded some percussion and keys sounds from Muse Hub, and cannot figure out how to open them or import them into Audacity. They are .sts and .spx filetypes. Any advice? Thank you, from my newbie heart.
The sounds you have downloaded aren’t sound files, they’re virtual instruments for Musescore. They don’t work anywhere else and aren’t even based off of MIDI.
The audio samples you’re looking for are in the sounds tab, in the elements section in musehub. These are WAV files which you can drag’n’drop from the musehub into audacity.
