That's the steering system of the Dolby Pro Logic decoder in your receiver extracting the rear channel information. Because the process is very phase dependant, the swishing sound (phase shift) can be evident during action scenes with a lot of panning. The latest Pro Logic II is less susceptible to this effect.

When you can only hear sound from the front speakers, it usually means the sound card does not support surround sound, and/or the sound card is not configured correctly, the speakers are connected incorrectly or the speakers could be defective. First, make sure your sound card supports surround sound 4.1. A surround sound card should have a front and rear speaker jack.

This is typically caused because the home theatre receiver is not in Dolby Pro-Logic or Dolby Digital Surround mode. Different brands of home theatre receivers have different methods to put the system in this mode. It is usually controlled from the remote and often called "listen mode" or "mode". Also occasionally you’ll encounter a movie with little or no surround information on the soundtrack. The older the movie the more likely this to be the case.

If you can't hear sound from your speakers, it means the speakers are not connected properly, the sound card isn't setup correctly, or the speakers could be defective. First, check the speaker-to-computer connections. Make sure the cable connected to the "Audio In" jack on the speakers is also connected to the "Speaker Out" or "Line Out" jack on the sound card. You can test the sound card jack by connecting headphones to it.

You may not hear surround sound when you play movies or games if your sound card is not surround sound capable. The movie/game must also support surround sound. If you are not sure of either of these, check with your sound card manufacturer and read the documentation that came with your game/movie.

After the title page runs with both video and sound working, when the program tries to move to the next step I get the error "The program has performed an illegal operation and will be shut down." When I go to details it says, "VISITW95 caused an invalid page fault in module VISITW95.EXE at 0217:0041081a." I have tried other CD-ROMS and they work properly and all the software on my computer works properly as well.

No. You must hook the Xbox optical output to some device capable of decoding the AC-3 digital audio. There are NO EXCEPTIONS. You need either an AC-3 capable receiver or an AC-3 capable PC sound card with optical input.

Some Windows Media files (such as the streaming video in the courses) may not play correctly on Mac OS X computers without downloading the Flip4Mac player (free) from the Microsoft web site. After downloading the free player, the course streaming video plays correctly in the Safari browser. Some video files may not play correctly on Mac OS X computers without downloading the free DivX codec from the QuickTime Components page or the DivX web site.

No, the HDMI outputs on the Movie Player and the Movie Player 2 carry video and PCM stereo audio only.

The Kaleidescape Movie Player 2 supports both HDMI and component video (YPbPr) for high-quality video output.

Dolby Digital, Dolby Pro Logic II and DTS are all supported and processed. Remember all audio is processed by the Cell and developers can use whatever audio codecs they want…so this is only the beginning.

of a few years ago, most consumer off-the-shelf systems feature either 5 identical speakers or 4 identical speakers with a center channel modified for better placement on top of the television. For a home theater system designed primarily for watching movies, the center channel may be of dubious quality and design though. In many older (circa 2000 or so) consumer music-only surround system, the front speakers may be matched direct radiators and the rear speakers may be dipoles (see 1.10).

We have just recorded some new sound clips featuring our brilliant new vocalist Sarah Davies that we hope will show you that we really can perform to the standards we say we can.

When you play an audio file the sound content of the audio file replaces your microphone input. The other participants hear the sound, but you do not as RAT does not loopback your input. NB use the command line flag -allow_loopback to enable loopback.

Your film will be shown in Standard Definition in stereo or mono with an aspect ratio of 4:3. So you may shoot in HD, in widescreen, or in surround sound, but the film will not be projected that way. We require you to submit a Standard Definition, letterboxed, stereo or mono version of your film—anything else can lead to problems during our mastering process.
