They stream the data into a memory buffer and the actual 1X output is sent to the DAC from the memory, not the CD itself. Players like the memory player are more like a computer drive. They may interpolate to fill in the error with a "guess" about the music that should have been there. If it has to re-read a section of the disk it can't deliver the music in real time, so audio players typically don't re-read. When a regular audio player plays a disk in real time, it has to read it at 1X and get it the best it can the first try. Slow ripping does not improve error correction if no errors are popping up. If the drive is having trouble getting an accurate read in an error correction mode, it reads slowly. If an audio CD does not need to be re-read, it rips quickly. When you rip a CD on a computer, the drive has a similar opportunity for multiple reads within the confines of Reed Solomon. Exact audio copy fast install#If it never gets it right, you get an error message that the program can't install correctly. If the disk is in good shape, it reads the disk perfectly at 50X (or whatever.) If the disk is in poor shape, it tries until it gets it right. The CD drive can re-read the disk as many times as it wants. Data programs are not time sensitive when they install. There is a difference between error correction that picks up correct data from another interleaved area of the disk and interpolated data if all the areas for a frame are damaged. You might also check into the Reed Solomon C1/C2 error correction that audio CDs utilize. (Not many people want to hear Pavarotti sound like a chipmunk.) Note that real time playing is inherently a 1X speed. People want to hear music when they hit the play button so the amount of memory buffering available is nominal. On a disk in good condition the process is fast so there is no reason to slow it down. Ripping speed is simply a function of how fast the program thinks it gets an accurate read. My music server is based on Linux so most of my ripping is done with the CD Paranoia based system but the goal is the same. Depending on the extent of damage, portions of a CD simply may not be accurately read no matter what the effort. I've had EAC spend more than 30 minutes, an hour or more trying to rip a single regular length song. Lots of people like EAC as it puts forth more effort than most ripping programs to assure an accurate read. My question is this: if ripping speed doesn't matter and bit-perfect copying is assured so long as you rip with error correction, then why are so many audiophiles intent on using Exact Audio Copy and why does the Nova Physics Memory Player tout its Read Until Right methodology as a key component of its great sound? Something doesn't add up.
