ripping audio cd's really slow

trey85stang · 09-24-2005, 09:25 AM

When I attempt to rip audio cd's it goes painfully slow... I have a DVD/RW drive but the cdreader supposedly runs at 48x. This is on slackware 10.1, and it only happens with slackware, I have had other distro's on this same machine and never had this problem.

When I rip with sound juicer or grip, it only reads the cd at .5x? What could the problem be

(btw tip rip one track takes about 20-30 minutes.)

that does seems highly excessive, but there are standard things to check like DMA being enabled on the device. Also you might want to remove the Extra Paranoia options from cdparanoia in grip, that'll speed it up loads too.

I have the same problem with an older notebook and the integrated cd-rom-drive. Ripping is very slow and not really something to do with fun.

DMA is enabled, other problems are not there (as far as I can see).

I found out that there is a way to rip a cd nevertheless with the same hardware in a really good way. I open K3b and copy the audio cd - but with the feature only to create an image to disk (I choose a folder, where I can find the .wav-files after creating the disk-image).

These .wav-files are written very fast (I don't know which commands K3b takes for cdparanoia).

I navigate to this folder and rip the files with lame or oggenc.

This way is much more faster than any rip-program (I usually use rip as program).

So far my way to do this with my old notebook.

flux.

P. S.: K3b does it although there is no cd-writer in the notebook. Reading is no problem for K3b.

Code:

root@darkstar:/home/trey# hdparm -i /dev/cdrom

/dev/cdrom:

I'll try disabling the paranoia options...

Flux, can I get id3 tags by doing it like that?

i disabled all the fluffy cdparanoia options.. it spead the process up a lot. Im now ripping at 3-4x. So now the process is a lot quicker, about 15minutes or so to rip the whole cd.. then another 5-6 minutes to encode. Much better

I've noticed that cd-rw drives are usually slower in linux than windows despite the tweaks made with hdparm. Does anyone know the reason for this or am I just imagining things? :O

acid_kewpie · 10-03-2005, 06:48 PM

drives were a lot slower using scsi emulation. a 2.6 kernel set up right i.e. without emulaion, should be noticably faster

ittut · 10-04-2005, 05:02 AM

I'll try that, thanks

I run 2.6.X and can rip and encode an entire CD in ~6 minutes, depending on the CD length, with custom script. I never tried it with 2.4.X so I couldn't tell you the speed up.

liquidtenmilion · 10-04-2005, 07:40 PM

2.4 is slower, but not significantly slower, maybe it takes 1 or 2 more minutes.(but then again i'm probably limited to my processor) I have a 52x ide cd drive.

would you give me more information about your way to rip a CD and your custom script?

Would be very nice ...
