What is dolby stereo sound?

Dolby Labs started in the audio industry as a noise reduction specialist. This was during the era of tape based analog recording when one of the big issues was tape noise. The noise could be heard as a background hiss. Dolby's early products were noise reduction hardware that could be used during the recording and playback process to reduce the noise. It was used in virtually all domestic and professional tape machines as well as film soundtracks. Movies that used the technology normally credit Dolby with the double D logo and the "Dolby Stereo" text. The original noise reduction processes are almost obsolete with the advent of digital recording (no tape means no tape noise). Dolby have since moved into other forms of audio processing, surround sound in particular. Movies of today no longer carry the DOlby Stereo credit but Dolby Surround credits instead.


What is the difference between 5.1 dolby digital and 2.0 dolby digital?

Dolby 5.1 is a multi-channel audio format. Basically meaning, it's surround sound. There is a Left, Centre, Right, Left Surround, Right Surround and LFE (Sub) Speaker. Dolby 2.0 is simply 2 speakers, Left and Right. Similar to the Stereo sound you get from your TV. The Dolby bit means it has been compressed and encoded using Dolby technolgies, normally AC3.


What is the frequency response specifications for 7.1 surround sound channels Are all 7 about 20 to 20K Hz other than center which is usually voice dialog only?

Unlike the old Dolby Pro Logic Surround, Dolby Digital 5.1 and 7.1 have full frequency response abilities for all surround channels. In reality, most sound engineers limit the frequencies sent to the rear and surround speakers since the typical home setup has smaller speakers in these positions. Of course, the LFE channel is limited to 100 to 150Hz for true sub bass operation, but can be pressed into service to provide low frequencies to compensate for small left and right front speakers.

Most dvds today are only rendered in English 5.1 surround there are some dvds that have English 2.0 dolby surround as a second option how come new DVDs today don't have that second option?

Some DVD's have a stereo 2-channel mix (Dolby Digital 2.0), but none feature a Dolby Surround or Pro Logic Surround option in the menus. This is because all DVD players can submix the 5.1 Dolby Digital track and output a Dolby Pro Logic Surround signal through the analog 2-channel outputs.

What is the benefit of dolby pro logic on a40 headphones----how come when dolby is activated sound seems more underwater whereas when dolby is off sound is more in your face?

Dolby Pro Logic (and Pro Logic II) are audio postprocesses that take 2-channel (stereo) sound and "convert" it into six channels. The resulting channels are Left, Center, Right, Left Surround, and Right Surround with a Low Frequency Effects channel (LFE). This configuration is also called 5.1.In the case of headphones, there may be multiple speakers for each ear, but for all intents and purposes we can consider them as having a "Left" speaker and a "Right" speaker.The Astro A40 headphones, has an additional postprocessing stage called "Dolby Headphone". This technology takes multichannel sound (5.1, discussed above) and virtualizes it so that the content may be reproduced over headphones. The result should sound like you are listening to 6 different speakers at once.The "underwater" sound you mention is simply the artifacts associated with the virtualization process. Some people enjoy the immersive sound Dolby Headphone and Pro Logic provides, and some people don't.
