If by bitstream PCM you mean exclusive mode, then you're correct. PCM is sent through Windows Audio. However, that depends on your audio renderer not the decoder, so, you need an audio renderer that can use exclusive mode to bypass the Windows Audio settings. ReClock is one such audio renderer.

All DTS formats will be decoded by the ArcSoft decoder if its installed.

When you implement channel downmixing, can you add an option to boost the volume of the center channel?
A common problem with downmixing 5.1 AC3 (and probably other formats as well) to stereo is that the volume level of the sounds that originate from the center channel (typically voices) are way too low compared to the volume levels of the sounds coming from other channels.

If possible, i would ask the decoder to downmix AC3, as it usually carrys special matrix information how to downmix into stereo.
Anyhow, i won't be doing downmixing yet, i rather work on improving sound quality, rather then destroying it.

Hi Nav, I think I must be missing something very fundamental here; or maybe not doing something right. I just tried testing LAV splitter/ LAV audio (version .26) with dtsdecoderdll.dll for the first time. For some reason I only see the new DTS, DTS-HD under SPDIF/HDMI. I dont see them under "Formats" section. I have no problems making a filtergraph for TrueHD, AC3, and everything else in the "Formats" section of the LAV audio filter prop screens. But I can't use LAV audio filter for DTS-MA.
I've been using Arcsoft Audio Decoder HD (ASAudioHD.ax) using the other method with win.ini to decode all possible audio formats (including dolby digital plus) at 24 bit/48kz (and above) to my 5.1 analog speakers. Thanks, -MKANET |

If "dca" is enabled in the LAV Audio options and the Arcsoft dll is in the LAV folder, then it should be working. You can double check in the LAV Audio status tab. It should say "dts" or some variant depending of the audio of course. If it says "dca" then it's not using Arcsoft.

Resampling itself does not improve audio quality, in some cases it helps to workaround bugs in audio drivers or hardware. |

Thanks, its now able to decode. In Win.ini, I used to set speaker output to 5.1. IIRC, Nav mentioned that Win.ini isn't necessary anymore. How do I set speaker configuration to 5.1 then? Also, is there an option for Dolby digital plus decoding? I have all the checkboxes now selected under formats. No big deal if its not supported, just curious, since that format is also supported under Arcsoft Audio Decoder HD.

Hmm... I thought that arcsoft audio decoder did the downmixing (set in win.ini)... originally a registry setting for the TMT player) in addition to decoding audio.
[HKEY_LOCAL_MACHINE\SOFTWARE\ArcSoft\MPEG Codec\Decoder Setting\] AudioOutputMode=13 AudioDynamicRange=1 I already use reclock WASAPI. It seems like one of the other dlls in the arcsoft codec folder might be handling the downmixing part. Quote:

The ArcSoft DirectShow component controlled the downmixing. Those settings have no effect on LAV Audio.

For actual 7.1 content, you can downmix either with Windows (when you set the mixer to 5.1) or with your receiver. The Windows mixer allows to even set 2 "virtual" surround backs, so you can do that, which is better than just setting it to 5.1. |
