« on: 29 Mar 2019, 11:03 pm »
Just a quick question so that i understand the CD ripping process. if i am ripping CD's to hard drive  ( sd or spinning ) does the CD ripper have a clock that is put into use?

Thanks

Not sure what kind of clock you’re referring to.

Don't know if this helps?  https://en.wikipedia.org/wiki/Ripping

I find this software works well - https://www.dbpoweramp.com/cd-ripper.htm

Ripping is making a copy from a digital media (optical disk) to another digital media (HD, SSD)
As you stay in the digital domain jitter is not an issue, if that is what you are asking about.

Hello Phil-
I have some coveted songs on a DVD that are 24/96.
How do I rip songs from a DVD?
Thank you.

You can use VLC  https://www.videolan.org/index.html  Providing you have a DVD capable computer drive.

It can rip most anything.

Like any digital data transfer, there must be a clock to move the data from the optical disk to the hard disk or SSD etc..

The clock in the CDROM drive reads the data in chunks at a high rate, (much higher than the sample-rate) that are put into a FIFO memory and then it is buffered in the computer memory.   This way, the chunks that are spooling out on one clock frequency from the CDROM drive don't have to match the computer system clock.

Then it is moved from memory to hard disk storage using the computer system clock.

Once stored on hard disk, the ripping application can reformat or resample the data into .wav, FLAC or other formats and check both the data and offsets for accuracy by comparing these to other rip history stored on various servers on the web.

ExactAudioCopy (EAC) for Windows, XLD for Mac. Avoid the itunes native ripper either way.

For XLD, suggest reading this configuration guide

Steve,

a voice known and trusted.

so if i understand you correctly there is a clock in the CDRom drive. the reason that I asked is that I would seem that given the nature of CDRom's and mass market, the internal clock inside would be cheap. even though the ripped data will be reclocked is there a chance that some jitter would be injected into the transfer? sorry if this seem like a dumb question.
