I found "this article":http://www.cdmasteringservices.com/dynamicrange.htm while researching the CD vs. vinyl debate (although this one is purely about CDs). I had always heard that CD quality music is the best technically, so I was shocked to read this. Although it's probably old news to a lot of you. I think it's pretty relevant with what's happening to major labels at the moment.
"What happened to dynamic range? That's a question that should be asked of record labels, producers, artists, and last but not least, recording and mastering engineers. The question needs to be asked because we're the ones responsible for what's happened to our music. Much of the music we listen to today is nothing more than distortion with a beat. It's not because the music is inferior. Great music is suffering because it lacks dynamic range. When music lacks dynamic range, it lacks punch, emotion, and clarity. The record labels blame digital downloads, MP3s, CD burners, and others for the lack of CD sales. While there is some truth to their constant whining, they only have themselves to blame for the steady decline in CD sales. The record labels need to reevaluate what they consider to be good music.
"Much of the music being produced today isn't music at all. It's best described as anti-music. It's anti-music because the life is being squashed out of it through over compression during the tracking, mixing, and mastering stages. It's simply, non musical. It's no wonder that consumers don't want to pay for the CDs being produced today. They're over priced and they sound bad.In 2005, CD music sales in the U.S. slid to their lowest level since 1996, ending all hopes that the music industry's downward sales trend may have bottomed out. This is according to sales data released by Nielsen SoundScan, a tracking firm that measures point of sale purchases across the U.S. Although there was a slight upturn in sales in 2004, total CD sales fell 7.2 percent from 2004 to 618.9 million units in 2005, the lowest since 1996, when they were 616.6 million. It's time for all of us in the music industry to wake up! Our musical heritage is being threatened by this wave of anti-music.
"What is dynamic range anyway? Dynamic range is the difference between the softest and loudest sounds we can hear. Or, to put it another way, the difference between the softest and loudest sounds in a recording. Dynamic range is measured in decibels (dB). For comparison, the typical dynamic range for a cassette recording is around 60 dB, while CDs can reach a dynamic range of 96dB.
"For years we've tried to recreate the excitement of a live performance by trying to maintain as wide a dynamic range as possible. This has always been difficult with analog recording. We had to keep the softest signals above the noise floor while keeping the loudest signals below the level of distortion. To keep the soft signals from being buried in tape hiss, we had to record with as high a level as possible. To keep our loud signals from distorting, we had to compress the signal which resulted in a restricted dynamic range. As the years went by, many improvements were made in recorder and tape technology. This, along with various types of tape noise reduction systems, helped to improve the dynamic range of our recordings, but it was still limiting.
"Then one day we awoke to a new technology, 'digital recording.' Wow, now with a dynamic range of over 90 dB, our recordings could almost rival a live performance. Well, in theory, yes. However, the music industry had other ideas.
"Rather than use this new technology to take advantage of it's wide dynamic range, the music industry went in the opposite direction. They decided that louder is better. Suddenly, we found ourselves in a race to see whose CD was the loudest. The only way to make CDs louder was to keep compressing the signal more and more. That's where we are today. Everyone's trying to make their CD sound louder than everyone else's. The term that is used for this process is called, hot. Yes, most of today's music is recorded hot. The net result, distortion with a beat.
"In December, 2001, several prominent individuals in the recording industry served on a panel to judge the best engineered CD for the Grammy's. After listening to over 200 CDs, they couldn't find a single CD worthy of a Grammy based on the criteria they were given. Everything they listened to was squashed to death with heavy amounts compression. What they wound up doing was selecting the CD that had the least amount of engineering. In reality, the winner didn't win because of great engineering, he won simply because he had messed with the signal the least. On second thought, maybe that was great engineering. For the record, the winner that year was Norah Jones' CD, 'Come Away With Me.'
"Here's a quote from Roger Nichols, one of the participants on that panel. 'Last month, I listened to all the CDs submitted to NARAS for consideration in the 'Best Engineered Non-Classical' Grammy category. We listened to about 3 to 4 cuts from the 267 albums that were submitted. Every single CD was squashed to death with no dynamic range. The Finalizers and plug-ins were cranked to 'eleven' so that their CD would be the loudest. Not one attempted to take advantage of the dynamic range or cleanliness of digital recording.'"
