I've been playing around with the Xbox 360 for a while now and have a few questions for you. Feel free to pick and choose what to answer as you see fit.
First, it seems to me that the 5.1 tracks for HD DVD trailers from The Look and Sound of Perfect website streamed through Windows Media Player 11 and movie trailers from Xbox Live have especially heavy LFE hits. Are you aware of anything in the Xbox 360's decode/mix/encode process that would change LFE gain? Of course, it's possible that these trailer mixes are just LFE-intensive. Am I correct that the native audio codec is WMA?
Yes the audio is WMA. I don't know why LFE is so strong. Have a question into the team. Will you know what I find out.
Second, what are the chances that you could provide us with an official WMA/V 5.1 file to check channel levels for audio streamed from a PC or downloaded from Xbox Live? I am envisioning something like twenty seconds of 500 Hz to 2 kHz narrowband pink noise in each main channel and 40-80 Hz in the LFE at DN -31dB and -30dBFS and -40dBFS, respectively. If such a thing is publicly available, I am not aware of it.
Good suggestion. Let me look into this one also.
Third, are there any plans to enable the DTS and WMA encoders for applications besides HD DVD playback?
Nothing to announce yet. But I am hoping we can do something in the future.
Fourth, I have encountered some program material recently (primarily games) where the channel identification is apparently wrong - e.g. the C is coming from the R, the L/R are coming from the Ls/Rs, and the Ls/Rs are coming from the L and C. I am assuming this is an issue that should be taken up with the content provider directly?
Thanks again for being available to us.
Yes, this should definitely be taken up with the app developers.
