Overview of available test streams:


DASH:

Dynamic Adaptive Streaming over HTTP (DASH) is a modern, over-the-top streaming system standardized by ISO/IEC MPEG 23009-1. Content is typically stored in segmented MP4 Files and delivered over TCP/HTTP. Addressing of individual segments is achieved by issuing HTTP byte-range requests. The byte offsets of these segments are stored in a segment index box ('sidx') that is placed directly after the movie header ('moov'). The following examples are encoded and segmented according to the DASH standard. Since DASH allows for client driven bit-rate adaptation, each set of files is encoded in multiple bit-rates and accompanied by a manifest, the Media Presentation Description (MPD), that contains all necessary information to establish a DASH session.

  • ▼ Audio_Only_Stereo_Dash.zip (Size: 8.1 MB) (MD5 checksum)
    This zip contains a stereo HE-AAC and AAC-LC audio only DASH set featuring multiple audio bitrates. Use this set to test audio bitrate switching in a dash ready player.

  • ▼ Audio_Video_Stereo_Dash.zip (Size: 137 MB) (MD5 checksum)
    This zip contains a stereo HE-AAC audio with AVC Video DASH set featuring multiple audio bitrates and one video track. Use this set to test audio bitrate switching in a dash ready player together with playing a video track.

  • ▼ Audio_Video_5_1_Multichannel_Dash.zip (Size: 249 MB) (MD5 checksum)
    This zip contains a multichannel (5.1) HE-AAC audio with AVC Video DASH set featuring multiple audio bitrates and one video track. Use this set to test 5.1 multichannel audio bitrate switching in a dash ready player together with playing a video track.

  • ▼ Audio_Video_7_1_Multichannel_Dash.zip (Size: 305 MB) (MD5 checksum)
    This zip contains a multichannel (7.1) HE-AAC audio with AVC Video DASH set featuring multiple audio bitrates and one video track. Use this set to test 7.1 multichannel audio bitrate switching in a dash ready player together with playing a video track.

  • ▼ Audio_Only_Stereo_Adaptive_Bitrate_Switching_Reference.zip (Size: 11.4 MB) (MD5 checksum)
    This zip contains reference files without the DASH-Framework, but with a "pre-build" adaptive bitrate simulation applied. It features a defragmented stereo HE-AAC audio only MP4 File for decoder tests and a decoded stereo only wav file to verify the result of the decoder test.


HE-AACv2 Profile Level 6 test streams:

"ISO/IEC 14496-3:2009 AMD 4: New Levels for AAC profiles" adds new Levels to the AAC profiles as well as additional 7.1 multichannel downmix capabilities and new speaker configurations to the AAC world. Following test streams will especially test these new features:

  • ▼ iop_test_data_from_sony20131022.zip (Size: ~165 MB) (MD5 checksum)
    The zip archive contains documentation of the test settings (.pdf), 4 AAC-LC bitstreams (aac_71chFH_*.aac respectively *.mp4), 4 HE-AAC bitstreams (heaac_71chFH_*.aac respectively *.mp4) and the corresponding decoded wav files (7.1 channel output as well as 5.1 and stereo downmixes).

  • ▼ 14496-3_AMD4_streams_fhg_20131008.zip (Size: 87.5 MB) (MD5 checksum)
    The zip contains documentation of the test stream configurations (.pdf), 2 subfolders (aaclc and heaac) with bitstream (*.mp4) files and corresponding decoded wav files (3 versions: orig number of channels, downmix to 5.1 and downmix to stereo).


Metadata testset:

The following test streams are provided to test the audio specific metadata and is based on the assumption that mpeg conformance tests (e.g. SBR) are passed successfully. Test cases include metadata parameters like PRL, DRC or compression downmixing, including extended downmix parameters for 6.1 and 7.1 channel files as defined in "ISO/IEC 14496-3:2009 AMD 4: New Levels for AAC profiles".

  • ▼ AAC_Metadata_Testset.zip (Size: ~900 MB) (MD5 checksum)
    The zip archive contains the specification document of the metadata testset (.pdf), a directory mp4ff with the encoded bitstreams (.mp4) including a directory mp4ff/dec with the corresponding decoded wave files.
    The decoded wave files were generated via the mpeg reference software.
    All bitstreams are available as AAC-LC and HE-AAC. Stereo test bitstreams are additionally available as HE-AACv2.

  • ▼ AAC_Metadata_Feature_Testset_v1.0.zip (Size: ~44 MB) (MD5 checksum)
    The zip archive contains the specification document of the metadata feature testset (.pdf) and a directory mp4ff with the encoded bitstreams (.mp4). All bitstreams are available as AAC-LC and HE-AAC.
    The AAC bitstreams are designed in a way that allows for a rough verification of the metadata features by simple listening to the decoder output. This is particularly beneficial for assessing real-time applications.

Ancillary Interoperability Test Streams

  • ▼ realWorld_test_streams.zip (Size: ~11.6 MB) (MD5 checksum)
    This package contains a collection of bitstreams which have shown up in the field with different transport formats. These bitstreams can be used to test the behaviour of your audio decoder in various real-world scenarios. This package can be used to test whether an audio decoder is able to handle well-known pitfalls. Each bitstream is designed to check a different setup.
    The zip archive contains a specification document (realWorld_test_streams_v1.0.pdf) and 9 different bitstreams which are adequate sorted into the appropriated subdirectory (e.g. /realWorld_test_streams/sbrSignaling).
