The Capture Buffer is a temporary memory buffer used during Capturing.
Its purpose is to ensure that CD reading proceeds as smoothly and quickly as possible.
To ensure the highest accuracy and speed, Riptastic! will always read from the CD as fast as possible (see also High-Speed CD Reading).
However, due to the fluctuating environment of your computer or other factors,
your computer may not always be able to handle the data as fast as your CD-ROM drive is capable of reading it.
The Capture Buffer provides a means to decouple CD reading from your computer's processing of the data.
If your computer is not able to keep up due to a temporary or brief sustained condition,
the Capture Buffer will hold the data read from the CD temporarily until your computer is able to deal with it.
You can compare the reading vs. writing speed in the details are of the Capture Dialog during Capturing.
The Capture Buffer will be used when writing speed falls below reading speed.
If your computer is consistently unable to keep up with CD reading, the Capture Buffer will eventually be consumed,
and CD reading will have to be slowed to compensate or the Capture Buffer will become too full and overflow.
There are numerous things that can affect your computer's performance at any given time,
such as the Windows operating system itself or other programs you have installed or running.
Your computer's performance is also dependent on the CPU, CPU speed, amount of RAM, speed of your hard disk, and operating system.
In general, Windows 2000 and XP are better at handling multi-threaded applications like Riptastic! than other versions of Windows.
Should you encounter poor performance during ripping or if your buffer consistently becomes full, here are some things you can try to help, listed in the order you should try them:
Close other applications during ripping, as they may take up CPU resources.
Is something else making your hard disk busy during ripping?
You may have something going on in the backround that makes your hard disk busy and prevents Riptastic! from writing to the hard disk as quickly as reading from the CD.
For example, while ripping are you...
- ...searching for files on your hard disk?
- ...running on a machine that's used as a file server?
- ...running a web server?
- ...running Kazaa?
Defragment your hard disk.
A badly fragmented hard disk will bog down writing speed.
Try disabling One-Pass Extraction.
With one pass ripping, Riptastic! will encode your file simultaneously during CD reading.
Some CPU and operating system combinations may not be able to handle this.
When one-pass ripping is disabled, no encoding will happen at the same time as CD reading.
You can disable one-pass ripping by unchecking the "One-pass" option on the General Options toolbar.
Increase the buffer size in the Capture Options.
Experiment with larger buffer sizes, depending on the amount of RAM in your machine.
Be sure to watch the buffer usage displayed in the Capture Dialog during CD reading.
That might help give you a clue as to how big the buffer needs to be.
If you have less than 128MB of RAM, consider adding more RAM to your machine.
This will improve your machine's overall performance.
If you're running Windows 95, 98, or ME, consider upgrading to Windows 2000 or XP.
Windows 2000 and XP in general perform better than Windows 95, 98, and ME.
