TAS Recommended CD Tweak….
LOL. Why bother with tweaking CD's when you can build an anti-gravity space ship. Yes, indeed, there is a patent too The way I see it your CD player is a rotating mass and therefore you should be able to fly using three or four players and some Duct Tape, of course... |
Shadorne, there are many audiophiles, even some with credibility, who claim that copies of CDs actually sound better than the originals. How can this be? If I trust in science then I can only assume it is mostly the placebo effect. In some rare cases, no doubt there may be an explantion. (For example, a wobbly CD might cause the laser tracking to draw power in an oscillatory manner and cause jitter in the DAC via a feedback mechanism from the shared power supply.) As a generality, burned copies of CD's should be the same and indistinguishable from the original. The error correction that Eldartford mentions practically ensures the bit stream read from the disc will be perfect and identical. As I mentioned above, if this were not true then PC's would not work and our whole computing industry and internet would be on its knees. |
I suggest you read up on error correcting encoding. Yes it is based on Reed-Solomon Interleave. However, contrary to what Eldartford mentions, if the error correction fails (a really badly damaged CD) then most players will "interpolate" between data points. On a bad CD with "CD Rot" it can actually sound exactly like Vinyl surface noise (pops and clicks). If error correction did not work to way more than 99.9999% accuracy then your PC that you are using to view this thread would crash constantly (perhaps it does and you need a new hard drive...). Despite the fears propagated by analog users about CD accuracy, all the science suggests that CD discs and readers are generally orders of magnitude (10's and 100's of times) more accurate than any analog reproduction. Digital is the only way to preserve data such that it can be copied thousands and thousands of times without error - this is because errors do not accumulate as they do in any analog chain. All this makes computing, satellites and other amazing things possible, stuff that purely Analog systems are incapable of. Of course A to D and D to A conversion is a crucial step and it is fair for analog users to criticise the quality of this process, however, this step occurs after the data has been read, decoded and error corrected from the disc. |
Shadorne, there are many audiophiles, even some with credibility, who claim that copies of CDs actually sound better than the originals. How can this be? Another explanation might be that some users CD playback equipment might simply be faulty - to the point where even the disc type has a bearing on the sound. Or that the burning program is not actually making an identical copy (some programs will re-dither re-sample when converting redbook CD data to a PC file on the computer and the then back to a CD redbook file. Some programs may even have bugs.) I use this SeedeClip and it certainly does alter the sound as it tries to reduce the tens of thousands of flat top clipping on your average modern crap hpercompressed CD track. BTW - When CD data flat tops then it is possible that the actual waveform it represents is actually BIGGER than CD redbook format specifies and exceeds what D to A converters can handle - at this point a CD is illegal or out of spec (most rock/pop CD's today are out of spec) and it may sound different from one CD player to another (depending on how the D to A converter behaves when trying to reconstruct an illegal signal - one that exceeds the redbook format itself...) |
