Generate a 4-track-stereo-testfile which helps to distinctively check audio channel mapping.
#!/bin/sh
# Generate a 4-track-stereo-testfile which helps to distinctively check audio channel mapping.
# Each stereo-pair contains the same phase-correct frequency on each ear
# (increasing frequency from lower to higher pairs), with brown noise overlayed
# on the right ear.
#
# When channels are swapped, the frequency on the left and on the right ear
# don't match which can be easily detected.
