5.1 Sound Test File Free On TheirDolby has a few for free on their web site as well: So far I havent found a way to play any of them though.I was hoping my Yamaha RX-V683 would play them directly from a USB drive, but it cant seem to handle the official MP4 files from Dolby, nor any of the ones from demo-world.eu, Demolandia, or elsewhere.View entire discussion ( 11 comments) More posts from the hometheater community Continue browsing in rhometheater rhometheater Your one stop for all things Home Theater (except soundbars).

LFE and SBR Test This tests for proper bass management and reproduction of the SBR portion of the HE-AAC bitstream. This bitstream contains: Bass Management - 63 Hz tone -18 dBFS, 2 seconds Left Front Center Right Front Right Suround Left Surround LFE ( -28dBFS) SBR - 6, 8, 10, 12 kHz tones -18 dBFS, 0.5 seconds each Left Front Center Right Front Right Suround Left Surround Spoken Channel Identification in English Narration: Center channel There is a 1 kHz -18 dBFS tone in the center channel throughout.

Hold SLM next to subwoofer) If full-range speakers are used, the 60 Hz tones should play through each speaker individually, though levels may vary due to standing wave or resonances in the listening rrom. The LFE signal is encoded 10 dB lower to account for the 10 dB gain in the LFE channel in the playback amplifers bass management circuits. ![]() If the decoder is only decoding the AAC-LC portion of the bitstream, only the first two tones will be heard. This is at the encoded bitrate of 160 kbs, at other bitrates the SBR crossover frequency used by the encoder will vary, resulting in more or less tones being heard. Missing tones in only one channel may indicate a speaker problem.

Troubleshooting The MPEG-4 AAC audio bitstreams above are presented as HTML5 audio objects - which should play back correctly in: Microsoft Internet Explorer 9 (Win 7 PC) Apple Safari 5 (Win 7 PC) Google Chrome (Win 7 PC, Mac OS, Android) when your computer has 5.1 channel speakers connected or connects via HDMI to a 5.1 or better surround sound AVR or home theater system. Note that many browsers and media players (particularly on mobile devices such as the iPhone) will output a stereo downmix from these streams, even if they dont support multichannel output. The bitstream files, if downloaded locally, should also play correctly in: Microsoft Windows Media Player 12 (Win 7 PC) Apple QuickTime (Win 7 PC or Mac) VLC Player (Win 7 PC) No sound or no rear channels Check the troubleshooting page. Channel Support The AAC codec family has supported up to 48 channels of audio since its initial development through predefined channel configurations and a flexible escape mechanism. ![]() Values 8-15 were added in AAC Amendment 4 This channel configuration value is specified in the AudioSpecificConfig structure of the AAC bitstream. When the channel configuration value is set to 0, the channel configuration is not predefined, but is explicitly described in the Program Config Element structure. ![]() For information on these structures, refer to the Fraunhofer Application Bulletin AAC Transport Formats or to the MPEG AAC standard: ISOIEC 14496-3.) Supplying the 7.1 configuration with the PCE escape method was necessary since the only predefined 7.1 configuration was the theatrical SDDS speaker configuration of five front speakers and two surround speakers. Thus, the more common BluRay 7.1 configuration with three front speakers and four surround speakers was specified using the PCE structure. An amendment ( ISOIEC 14496-3:2009Amd 4:2013 ) to the AAC standard also allows signalling the BluRay 7.1 configuration in the channel configuration field by using the value 12. An AAC decoder is also required to continue decoding configurations sent in the PCE. More importantly, AAC lacked profiles requiring 7.1 support, with a level 4 or level 5 decoder only required to support 5.1 decoding. The amendment includes level 6 to require 7.1 decoding. Also, the amendment specifies a method for controlling the downmixing of 7.1 channels to 5.1 channels with controlled gains, much as the existing standard does for 5.1. The amendment also includes the extra loudness metadata currently specified in DVB into the AAC specification. Channel Identification Spoken Channel Identification per ISOIEC 23001-8, 48 kHz sampling rate, AOT 5, 224 kbs, explicit signalling, backwards compatible, BluRay 7.1 configuration signaled with PCE.

This bitstream is provided for verification of 7.1 decoder implementations.
