CD Compression Depression Music Industry Idiocracy

CD Compression Depression Music Industry Idiocracy

Imagine, if you can, going to Paris to see the Mona Lisa. You wait in line for hours only to come to what appears to be a postcard of the Mona Lisa placed where the original had been. You ask the museum staff what happened to the original and you are told that this representation is what is required for the commercial success of the painting. Totally disgusted, you walk out with a severe case of what I call Compression Depression. The music industry as of late seems to be no different as they pump up the output levels and lay on the compression to play into the LOUDER is better mentality.

Dolby Digital LIVE Technology Overview

Dolby Digital LIVE Technology Overview

We are consistently asked about connecting a PC to a home theater system. It's not as easy as it sounds. For example, while many sound cards on the market can pass Dolby Digital and DTS "raw" signals for decoding by the receiver, most EAX/A3D surround games are only able to be output via the sound card's analogue outputs.

Many people have asked us about connecting a PC to a home theater system. It's not as easy as it sounds. For example, while many sound cards on the market can pass Dolby Digital and DTS "raw" signals for decoding by the receiver, most EAX/A3D surround games are only able to be output via the sound card's analogue outputs. Dolby Digital and DTS have both offered solutions to allow for a real-time, digital 5.1 encoded signal from a PC to be made to your home theater system.

When our friends at DTS offered to fly me to San Francisco to cover a seminar they were putting together, I was intrigued. From it's somewhat generic sounding title I was at a loss to figure out how this seminar presentation would play out.

The Case for NOT going above 0 dBFS For Digital Playback Systems

The Case for NOT going above 0 dBFS For Digital Playback Systems

I first became aware of this issue back in the early 90's when I was testing a DAC that used a Burr-Brown Digital Filter and D/A Converter. I observed that the 1kHz square wave test from CBS CD1 test disc was being clipped. I knew that the analog low pass filter had plenty of headroom, so I decided to contact Burr-Brown and speak to an applications engineer. When I explained to the applications engineer exactly what I was observing he remarked that this test went over the 0 dBFS limit and was clipped by the digital filter.

Issues with 0dBFS+ Levels On Digital Audio Playback Systems

 Issues with 0dBFS+ Levels On Digital Audio Playback Systems

When you make a digital recording, an analog waveform (represented by an electrical signal with a continuously varying voltage) is sampled at regular intervals and converted to a set of numbers. Each number, or digital sample , correspond the voltage of the electrical signal at a specific point in time. These numbers are stored in binary form with a specific word size (typically 16-24 bits). The minimum and maximum numbers that can be stored depends on the word size, and corresponds to the voltage range of the electrical signal.

Yes, you have heard all the arguments before, and you are probably sick and tired of it. LP vs digital is a "religious war" that has been played out by various audiophiles ever since the CD format was introduced in the early 1980s.

With the advent of home theater, consumers are continually demand higher performance. As technology improves and becomes more competitive, increased performance is realized at lower cost to the consumer. The market floods with newer and newer technology, allowing consumers to be less easily impressed and more picky, sometimes loosing touch with what was involved in producing this marvel of technology that only a few years ago, would have been a nearly impossible feat.
