Encoding the sound to MPEG-2 Layer II for DAB, MPEG-4 HE-AACv2 for DAB+ or video in MPEG-4 H.264 for T-DMB beforefeeding it to the multiplexer.

Tools for audio encoding

  • toolame MPEG-Layer II encoder (DAB)
  • CRC-dabplus HE-AAC encoder (DAB+) from CRC (warning, it is not free/open source because of royalty)

These tools can take a file or a raw PCM stream as input.

mpg123 can be used to take Internet radio stream and convert them from mp3 to raw PCM samples.
