I Am Legend trailer 5.1ch Dolby Headphone DH1 I Am Legend trailer 2ch downmix by FAAD decoder normalized (no DH) I can assure you that the action sequences in District 9 for instance sound a whole lot better with Dolby Headphone enabled. These samples are 192Kbps MP3 files for size reasons. The slight metallic high-end ringing to the deep bass is an encoder artifact from the conversion to MP3 using the LAME encoder, and it was still present when I tried 320Kbps. How to get it working for AC-3, AAC, and DTS multichannel sources The channel test clip was taken from and the I Am Legend trailer was from. In a previous post I explained how to setup Media Player Classic Home Cinema to use a third party h.264 decoder with DXVA support. MPC-HC has several key advantages as a media player – it’s open source, it’s lean, it’s extremely configurable, and it plays pretty much any format. Many people use MPC-HC for their Home Theatre PCs, hence this article.Ī guide for configuring Dolby Headphone using PowerDVD’s CyberLink Audio Decoder already exists (with files): I use it for my Sony Vaio P to keep CPU use as low as possible on its rather limited Intel Atom processor. However that information isn’t sufficient. The complication is that when this decoder is used outside the PowerDVD software, it only works with DTS audio streams even though it should also support AC-3. The next piece of the puzzle can be found here on the forum for Zoom Player, a commercial media player: Reading around, it seems that the AC-3 support works in Windows XP but not in Vista nor in Windows 7. The important point is that the CyberLink decoder can accept a multichannel LPCM input, so you can use another decoder ( ffdshow tryouts in this case) to convert the source bitstream into LPCM first, then feed that to the CyberLink decoder. ![]() This means that multichannel AAC audio found in MP4 containers could have Dolby Headphone applied too. The above post describes how to do this for Zoom Player, but we’re interested in MPC-HC. The next obstacle is figuring out how to link multiple decoders together in MPC-HC – something I couldn’t find any info about despite spending hours searching online.
