This is a collection of well-mastered pop CDs that have good micro (and macro) dynamic content. Microdynamics contain the transient movement or dynamic rhythm of a recording. Transients also affect perceived loudness. Macrodynamics contain the variations in average loudness over time. As we move into higher resolution recordings, I hope that DVDs, DVD-As, and SACDs will make it into this list. I've organized the recordings in order of increasing intrinsic loudness. Intrinsic loudness is the perceived loudness of a recording at a known position of the monitor control. So we can measure the difference in intrinsic loudness between two CDs by observing the difference between the two monitor positions required to make them sound equally loud. Remember that we have no control over where the consumer sets his personal volume control, so the whole idea of "absolute loudness" is a fallacy. That is why I've introduced the term "intrinsic loudness" to help us compare recordings at a given known position of the calibrated monitor level control. Also note that high intrinsic loudness necessarily produces lowered microdynamics because of the compression/limiting required to prevent peak overload.
(oh and internet downloads are out, at least till we have Gbps connections and very high quality files..... by definition, if I could download my entire music library, it'd be in a format so compressed that a CD would be better anyways. =P)
That approach only applies for comparison of different albums on CD, not different masterings on different formats.How accurate would that metric be for vinyl? Normalizing a digital transcription of a vinyl album against a CD counterpart is a nonstandardized process, and any absolute RMS metric is going to be corrupted by that.
You have to match the compression curve in order for expansion to give a decent result but it's even more complicated than that due to thresholds, attack and release times and other parameters.
It's interesting that you mention Oasis. Out of many compressed albums I have, Oasis (What's the Story...) is by far the most compressed album I own. It is unlistenable, which is a shame.
....Thanks everybody for the replies, first of all So am I to understand that there is usually no difference in 'quality' between CDs, vinyl or anything else because they are all mastered more-or-less the same?
Hmmmm. I can believe that the industry would do that, but if that's true why on earth do people always talk about vinyl sounding much more natural and what would be the point to SACD type technologies?
- About 6 months ago in the audio shop down the road from here, I heard Keane's Hopes and Fears first on CD and then on vinyl. Admittedly some of this difference was probably caused by the change in systems [the first was an Arcam seperate and the second, well I can't remember but suffice to say it was priced at about £10,000!], but even so the additional depth to the album on the record was staggering.....Oh and @the (What's the Story) Morning Glory post: in my experience, that's one of their least compressed albums. Don't Believe the Truth is a lot worse and that's saying something
Given that modern lossy compression is so good, and the loudness wars are a Great Scourge, would expansion be the next great challenge for all the dedicated people who've worked on Lame, Ogg Vorbis and all the others, or is the information hopelessly lost?
What do you think about this concept?http://www.digido.com/misc-content/honor-roll.html
Excellent."K-14" = -6dB on Bob's scale = 0dB on the current ReplayGain scale."K-20" = 0dB on Bob's scale = +6dB in ReplayGain.
or you need to hear from the horse's mouth (ie the mastering engineer) that less compression/limiting was applied. The latter is extremely hard to find
Ignorant question. I remember way back when, a friend who was serious about music but not an audiophool had a thing called a dynamic range expander, to cope with the compression needed for vinyl.I realise that nothing could be done about information lost in clipping, but would it be possible to do something digital to make quiet passages quieter?
Is this all about loudness was? Sound is being compressed to achieve louder record on a CD? Compression is being used to mask any artifacts or noises? What is the reason?
