xHE-AAC Adaptive Bitrate Test Files

Fraunhofer Institute for Integrated Circuits

Flat/Non-Fragmented xHE-AAC example files for adaptive streaming generation tools

The following example files are encoded in xHE-AAC and prepared to be used in combination with a fragmenter and manifest generator for streaming. There are three different bitrate versions of the same content that include time-aligned prepared SAPs/RAPs. These three streams can be used in combination with an xHE-AAC capable fragmenter and/or manifest generator to create files ready to be streamed via e.g. DASH or HLS.

Technical Details

  • A set of standard, plain/flat mp4 files (audio only with different bitrates and aligned SAPs/RAPs)
  • Bitrates: 24, 64, 128 kbps
  • Sample Rate: 48 kHz
  • Prepared SAPs/RAPs: Every 4.94933s (237568 audio samples at 48kHz)
