I just started digging into eac3 encoding and have been googling this and
that and have come up with:

ffmpeg -i front_left.wav -i front_right.wav -i front_center.wav -i lfe.wav \
-i back_left.wav -i back_right.wav \
-filter_complex "[0:a][1:a][2:a][3:a][4:a][5:a]amerge=inputs=6[aout]" \
-map "[aout]" -acodec eac3 -ab 999k outputfile.ac3

What I haven't been able to find are the available bitrates for eac3.
Obviously the normal ac3 bitrates up through 640kbps, but I do not know
what is available higher than that.  The 999k above is just a place holder.
