However, with the exception of some interesting possibilities, in most cases this is not the case at all. Even relatively new high-end HDMI-equipped motherboards, video cards, and sound cards may not be able to handle such large audio streams on their own. Ultimately it all comes down to what kind of input signal they can receive and what kind of signal they can output.<\/p>\n<p>In this review, we&#8217;ll take a look at all HD audio formats, their bitrate (streaming), and delivery requirements to the playback medium. In Part 2, we will continue to explore how digital audio streams can (or cannot) be handled in typical PC components. After reading both articles, you will need to understand in depth why so many home theater users use a variety of analog cables (three for 5.1 channels and four for 7.1) instead of HDMI to carry multi-channel audio wherever you need to go. &#8230; We will also talk about some of the workarounds associated with converting a digital to analog signal on a computer, rather than a receiver or preamplifier, often this option is the most affordable option for HD sound quality optimal. And finally, perhaps you understand why it is worth waiting a little longer to buy a Blu-ray player for your home theater system; This will allow you to take advantage of some of the new benefits that should appear before the end of 2008, but are not ready yet (at least they are not ready at the time of writing this article).<\/p>\n<p>The bitrate (or stream) associated with each format, as well as the number of channels, sample rates, and bit depths used to encode the formats.<br \/>\nWhether the SPDIF connector can provide the required stream for each format and what types of HDMI interfaces each format works with.<br \/>\nIn Part Two, we&#8217;ll look at PC software codecs to find out what formats they work with, as well as the types of interfaces that HDMI-equipped motherboards, video cards, and sound cards can support. And since new chipsets and interfaces are recently available (or will be available relatively soon), we&#8217;ll also explain how new and future hardware can provide simpler solutions for currently messed-up PC HD audio.<\/p>\n<p>Introduction<\/p>\n<p>High Definition Audio Formats (HD Audio)<br \/>\nBlu-ray discs can contain movie soundtracks in one of the following formats.<\/p>\n<p>PCM (linear PCM or LPCM);<br \/>\nDolby Digital;<br \/>\nDTS;<br \/>\nDolby Digital Plus;<br \/>\nHigh resolution DTS-HD;<br \/>\nDolby TrueHD;<br \/>\nDTS-HD master audio.<br \/>\nBefore moving on to a detailed consideration of the above formats, we note that Dolby technologies originated from Dolby Laboratories, a recognized provider of professional, semi-professional, and consumer multi-channel surround sound technology and noise cancellation. DTS (also called Digital Theater Systems) is derived from DTS, Inc. is also a well-known provider of digital audio technology that competes with Dolby Labs.<\/p>\n<p>PCM (linear PCM or LPCM)<br \/>\nPCM stands for Pulse Code Modulation and provides a digital representation of an analog signal that is sampled (digitized) at regular intervals (with a specified frequency in Hertz) and represented in binary form (with a specified precision &#8211; bit width). In addition to using PCM for computer digital audio and audio CDs, it is also used in some digital phone systems and in various digital video formats. In PCM format, audio amplitude values \u200b\u200bare represented using different numbers of bits (length); the soundtrack is usually digitized in 12 to 24 bit, but most of the time 16 bit is used in PCM studio encoding for Blu-ray discs.<\/p>\n<p>A PCM audio track can be an exact copy of a studio original encoded on an uncompressed disc if its bit depth is the same as the original. If the bit depth is reduced (as is often the case to save space allocated for storing audio on disk), this can cause a downgrade &#8211; for example, using 16-bit instead of 24-bit. From a technical point of view, downsampling is not the same as compression, although the precision of the resulting sound is decreased.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>High quality audio, what is it?
