Scenario 1 (Live Stream enconding and preparing for DAB muxer):
arecord -t raw -f S16_LE -c 2 -r 48000 -D plughw:CARD=Loopback,DEV=0,SUBDEV=0 | \
aac-enc-dabplus -b 24 -f raw -c 2 -r 48000 -i /dev/stdin -o /dev/stdout 2>/dev/null | \
mbuffer -q -m 10k -P 100 -s 360 > station1.fifo
Scenario 2 (Wave file enconding):
aac-enc-dabplus -a -b 64 -i wave_file.wav -o station1.dabp
