• Upmix Stereo To 5.1

Hello, This is a feature that I had strongly hoped would make it to Media Center in Windows 8, but didn't. Please consider this for a future update and/or the next version of Windows. Feature Request: 'Ability to Configure Stereo Up-Mix Capability in Windows Media Center and/or Windows Media Player from 2-channel Stereo to 5.1/7.1 Surround so Stereo MP3/WMA audio files output to.all. speakers in my system, not just the left and right main speakers.' More information: My audio content (MP3s, WMAs, etc.) are of course all 2-channel stereo format (left channel, right channel).

Upmix Stereo To 5.1

My home theater PC outputs to my home theater receiver (which is a 2012-model Sony 5.1/7.1 receiver) via HDMI. When I play 2-channel music (MP3s, WMAs, etc.) from Windows Media Player (WMP) and Windows Media Center (WMC) both in Windows 7 and Windows 8, I only hear music from the left and right main speakers,.not. the subwoofer not the rear surround speakers. In order for this to happen, WMP/WMC would need to 'up mix' the stereo signal to take full advantage of my physical speaker configuration (as specified in my Windows' Playback Devices configuration, which Windows is able to discern from the capabilities of my receiver). Media Center even has an Audio setup in which the end user configures the audio configuration to either Stereo, 5.1, or 7.1 yet music is still output over only two channels! I would like to see WMC/WMP either 'automagically' perform the 'up mix' or provide the user with an option to enable/disable it when 2-channel Stereo audio content is played. Too difficult?

Developer & IT.NET. Windows 7 upmixing from stereo to 5.1. Is this a setting I need to change or a limitation of some software component? May 21, 2005 UpmiX: tool to automate stereo to 5.1. UpmiX has evolved into a tool to process many kinds of. It's also nice to see BeSweet back in active development.

Rhapsody.com already accomplishes this with its online audio player! Note that my audio equipment has the capability of forcing output to two channels between the PC and the receiver, which my receiver will then up-mix, but this requires physically maintaining a dip switch and also several button presses on my receiver's remote. And this physical configuration must be updated each and every time I switch between audio and movies. Too much work when it could be accomplished automatically by WMP/WMC! Thank you for your consideration of this feature request!

Thank you for your consideration of this feature request! -Tretchie I had this issue with PC games/Music Am guessing you using the On-board audio? If so you need to buy a Sound card With Dolby Digital Live or DTS Connect. Thank you, sharnkly, I will investigate the audio adapter card you mentioned (as well as any others that may be suitable with my Sony receiver). However, I continue to hope that MS will provide an upmix solution for Windows Media Center that will obviate the need for add-on sound cards. In other words, I would like to be able listen to stereo content yet hear music out of all of my speakers without resorting to using additional equipment other than my Intel Z77 motherboard's onboard HDMI connector.

Honest Buying a sound card is the better option. If you like me and love your Music wait till you hear the difference a sound card makes it really is day and night. I see you trying to use HDMI for the Audio, I dont think you can get Sound cards witch output over HDMI they use Optical for the digital or jacks for analog. If you look under your Sony specs you should (hopeful) see Dolby or DTS some time even Both:) The card I showed you Supports DTS witch I think is the better of the two, but most people will have there own option on that.

Thing is, I use an Altona AT-HD570 HDMI 1.3 (3D) to intercept (they call it 'de-embedding') the HDMI audio stream and output to RCA Left/Right for use with both wireless stereo headphones and also Rockfish wireless speakers. The Altona device then passes the HDMI A/V signals along to my receiver, which is the pass-thru variety and does not possess a monitor port, hence the need for the Altona device.

My understanding is that Win7 will not output audio to two different ports. I need stereo L/R for my wireless equipment (read preceding paragraph) and also 5.1/7.1 to my receiver. I'd be interested to know if the ASUS Xonar accomplish this.

And if so, will it perform an upmix to the receiver and also output stereo to my wireless equipment? Thanks for taking the time to answer my inquiry!

Thanks for taking the time to answer my inquiry! Sorry I dont think the Asus Xonar DS will work for your needs:(. The ability of windows to better control audio channel output is definitely an issue that needs to be fixed.

It's really basic in this day and age where everyone and there mother has more than two speakers (i.e. I understand that certain media players, or certain decoders/channel mixers can be a workaround for this problem. But that's not enough. Today, we have many different sources for audio that are not just files on a computers: 1) Video/Movie files on computers (played through media center, MPC-HD or other) 2) MP3s/audio (played through same) But there is also: HTML5, webpages, Netflix, Amazon TV, Flash players, silverlight, etc.

Hence why windows needs an option at the level of windows audio decoder to better control channel outputs over LPCM-HDMI! Either Mirroring L/R outputs to rear/side speakers, or, formal upmixing algorithms like Dolby Pro Logic etc., applied before outputting over HDMI (Note I am NOT talking about bitstreaming!) This is a trivial problem using WASAPI or ASIO.

Why has windows audio not been properly updated since Windows XP!! Recently, HTPCs and Media Centers are becoming many households primary source of entertainment. Examples of some issues: 1) With no bitstreaming at all: - Configuring HDMI audio 'Playback device' to 5.1/7.1, and, - Using a software decoder/media player to decode Dolby Digital, DTS, DTS-True HD, or Dolby True HD, and sending the data in LPCM over HDMI to the receiver/soundbar - works totally fine for outputting 5.1/7.1 surround from those sources - windows (i.e. Software) completely fails in any ability to upmix 2.0 stereo sources to 5.1 or 7.1, or even mirror L/R channels to rear/side L/R channel for more room filling sound. Both these options should be available - upmixing with Dolby or other for videos and mirroring/doubling the channels for music/MP3s. Instead, windows audio sends silent channels over LPCM/HDMI when playing a stereo source.

This has the added awful effect of not even letting my receiver upmix/mirror the outputs. Hence, we need the ability to duplicate (for audio) and upmix (for videos) the L/R channels in a stereo source to the Rear L/R and or Side L/R channels through windows audio 'playback devices' configuration before outputting over HDMI-LPCM! In the day and age of 5.1 and 7.1 speakers this seems like such a BASIC feature that is missing.

Otherwise, so many of us with an HTPC in our living room as our main source of media can't play music mirrored through all our speakers, or watch videos with upmixed audio. HDMI is the new standard, so this should really become an option. I've done a fair amount of research on this problem, and do not believe there is any solution short of switching to optical (which I do not want to do because it can only carry 5.1) or, buying a fancy receiver instead of a soundbar with discrete rears and a subwoofer (which I have) to do the mirroring/upmixing for me.
