# This audio mode config is for the FC-HDS4 headset plugged into the
# main (EAR/MIC) audio jack on Caramel (iWOW DSK) or FC Caramel2
# development boards.

mic default {
	gain 8		# tuned empirically for far end subjective perception
	output-bias 1	# FC-HDS4 microphone needs 2.5V
# Mic appears to have flat frequency response, thus no FIR needed
}

speaker ear {
	gain 0		# left at default for now
# We do have frequency response data, but no flattening FIR filter design
# has been attempted yet
}

sidetone -17		# sounds reasonable

# Let's try using Pirelli's non-loudspeaker (handheld/headset)
# AEC config.
