Package: sound-juicer
Version: 0.5.12-1
Severity: normal
When ripping a CD with a lot of jitter[0], Sound Juicer is anything from 1
to 5 times slower than cdparanoia for some reason (often reading discs
at 0.2x-0.4x when cdparanoia reads the same disc in realtime).
Have tried using the --gst-debug flags to determine whether anything
serious is wrong, but I cannot see anything suspicious[1].
Steps to reproduce:
1 - Insert disc that has a lot of jitter. See [0].
2 - Begin extracting.
3 - Observe how the reading speed always is less than 1.
Machine is a AMD Athlon XP 2500+ with 256 MB RAM, and a Samsung 52x24x52
CD-RW drive. There is no unnecessary swapping. It does not matter what
final format I choose either.
If there is anything I can do further to help determine what the problem
is, please let me know. Thanks.
David
[0] I consider "a lot of jitter" to be when cdparanoia leaves dashes
after the arrow, and the status smiley always is a :-|. There are
no reading errors though. CD is around 10 years old, and plays
fine in any CD player I have.
[1] The progress bar in Sound Juicer is updated once every 5 or 6
seconds. With debug level 5 on, I can see that there is a lot of
calls to the scheduler for some reason, and occasional calls to
cdparanoia:src. Perhaps the already low throughput from the
cdparanoia source is causing a lot of overhead, making everything
slower?
