# Modified platform.txt to allow use of audio-specific build flags when used with the
# Teensy audio library. Make a copy of your existing platform.txt first! Then either
# (a) overwrite platform.txt with this file, or
# (b) hand-edit your platform.txt to include the references to build.flags.audio;
# there are 4 of these, in lines 26, 47, 50 and 56
#
# On a Windows system platform.txt will typically be in:
