What program can rip CDs at 1411kbps?

[Mark]

It's true that each CD/DVD in existence contains tens of thousands of errors which are corrected during playback by technology in-built to CD/DVD players.

[71 dB]

What?  Wav is 1440 not 1411.  The standard sample rate is 48kHz now.

WAV samplerate can be 8000, 11025, 22050, 44100 or 48000 Hz. Because we are talking about ripping CDs it's reasonable to talk about CD samplerate.

There are also problems with imperfections in discs.  Your exact CD is never exact, because small imperfections in the material of the CD actually cause it to lose data.  When you listen to a CD on your player, your player is constantly interpolating between missing bits in order to make the music sound right.  But these are just interpolations, not what is actually on the disc.  A quality CD player has a much better on board processor than a cheap player.  Sometimes a CD can be misread by the laser because of vibrations and other transient things.  Good rippers, like EAC or cdparanoia in linux, reread the data on the CD if they detect imperfections.   Usually after several passes the information is read correctly.

You may not be able to notice the difference, but if you are going to rip your CDs, you might as well do it right the first time.

That's true but if the CD is in good contition most if not all errors can be corrected. What's nice about EAC it actually tells how good the condition of the tracks in a CD is after the ripping.

There is a much bigger problem with CD sound quality people don't know about. It's difficult to understand without proper education about digital signal processing. Digital signals with finite samplerate are bandwidth limited. For example CD (44100 Hz samplerate) can't hold signals above 22050 Hz (half of samplerate). When the digital signal on a CD is read and transformed into analog signal it happens that the bandlimited analog signal can have greater (or smaller) values between the sample points then the sample values. Now, if the CD is done in a stupid way it may contain too large sample values so that when transformed into analog signal "explodes" and causes distortion. That's because in digital domain the signal can be manipulated and amplified in ways that do not obey the rules of bandlimited signals. The picture below illustrates the problem. The example show a square wave of 440 Hz at samplerate 6000 Hz. The black small squares shows the sample points. The upper version has full amplification and the sample values are +100 % and -100% in digital domain. The curve shows the corresponding analog wave after Digital-to-analog transformation. See how the curve has values outside the area of -100% and +100%. It goes even to a negative value of about 140 % !! Now, if your system is desined to handle analog values say up to 120 % this will cause distortion! The lower signal is the same square wave but attenuated almost 3 dBs so that the analog signal after conversion does not explode over the limits and distortion is avoided.

This "explosion" can happen also in digital domain if samplerate conversions are done (e.g. 48 kHz => 44.1 kHz during the production). If these conversions are done many times the explosion problem really explodes resulting very distorted sound. As sound engineers try to produce as loud CDs as possible (popular music) the problem is getting bigger and bigger. Older CDs had usually smaller save signal levels. These problems can be avoided simply using proper safe marginals of amplitude in the production.
