lc3dec

The lc3dec decodes LC3 data into raw audio.

Example pipeline

 gst-launch-1.0 -v filesrc location=encoded.lc3 blocksize=200 ! \
   audio/x-lc3,frame-bytes=100,frame-duration-us=10000,channels=2,rate=48000,channel-mask=\(bitmask\)0x00000000000000003 !\
   lc3dec ! wavenc ! filesink location=decoded.wav

Decodes the LC3 frames each with 100 bytes of size, converts it to raw audio and saves into a .wav file
