It may not seem like it, but CD’s have evolved tremendously since their introduction in the early 80’s. And while they still look the same as they ever did, CD’s have become profoundly more enhanced over the years—so much so that today’s compact disks far outstrip even the disks that were around as early as ten years ago. There’s one thing that’s still hanging on from the past, however: the concept of high resolution.
The idea of high-end audio in Chicago has been around practically as long as CD’s themselves, however the technology to support this superior quality has only made its way into the spotlight over the last decade or so. The concept of high definition and high resolution from the 1980’s and 1990’s was supported by hi-fi speaker technology, but today, we have the ability to translate that quality right from the audio CD itself, using tremendously advanced systems.
Digital to analog conversion
Much of the technological revolution of the early 2000’s was due in part to the introduction of D2A conversions (digital to analog). And while audio CD’s have evolved, our ability to expand the compressed data on them has advanced far beyond what people even deemed capable when CD’s were the “next big thing.” Today, you can take an audio CD, encoded normally, and through your computer or advanced audio system, output a sound that’s up to 8x the resolution of a traditional CD!
How is this type of high-end audio in Chicago even possible, you ask?
Well, it all falls on the superiority of the digital to analog converter that you’re using. Today, something like a high-end thermometer-coded digital to analog converter can convert nearly a billion audio samples per second, producing a sound that’s infinitely clearer and more refined than a traditional compact recording! On the lower end of the scale, something like a pulse-width modulator can also superbly increase the quality of music output by applying a stable voltage to an analog filter.
It’s all about the compression
When music and other audio is recorded on to a CD, it has to be compressed in order to fit the space that it’s given. However, the more compression that’s enforced, the poorer the sound quality can become when it’s decoded by an audio system or computer. The technology that’s meant to decode compressed data is evolving, however, allowing us to compress more and still get an amazing sound out of a disk.
With high quality sound being recorded directly on to CD’s themselves these days and the technology for decoding these disks now available from high quality audio retailers like Quintessence Audio Ltd., the ability of people to get the very most out of their sound is becoming common. Even the music industry is moving to a recording and compression platform that makes achieving superior audio possible through your computer at home.
