Audio Card Settings

Local play time (default : 1 second)

Each time you choose a Play local command (available from the Play local menu) a small portion of the sound material centered on the cursor, is played back. By changing the local play time you can adjust the length of the auditioned fragment.

Local processing time (default : 5 seconds)

Some utilities provided by DART XP Pro, such as restoration tests, equalizer and filters, allow you to preview results prior to full-scale processing. You can use this option to change the local processing (preview) time.

Response delay (default : 400 milliseconds)

For an average person it takes approximately 400 milliseconds to react to a sound stimulus. To compensate for this ‘response’ delay drop markers are placed in a soundfile with a 400 ms time shift. If you react a bit faster or slower, type in another value in the Response delay box.

Buffers per second during play (default : 16)

The number of buffers decides upon the accuracy of cursor positioning during playback. Depending on the speed of your computer you can decrease this number (which is recommended if skipping occurs during playback) or increase it (to guarantee very 'smooth' cursor movements).

Buffers per second during record (default : 16)

The number of buffers decides upon the frequency of updating of record counters. Depending on the speed of your computer you can decrease this number (which is recommended if problems with recording occur) or increase it.

Use fake VU display (default : off)

When enabled, this option causes DART XP Pro to check only every 128th sample for the purpose of record level/clip display. Otherwise, every single sample is checked. Using fake VU display is strongly recommended if problems with recording occur, e.g., when DART XP Pro is run on a relatively slow machine.

Play and Show (default : on)

When the Play and show option is enabled the plot of an audio signal shown in an active soundfile window is scrolled during playback (only when the Play all or Play from the cursor commands are used). To avoid skipping during playback, the time resolution factors equal to at least 100 are recommended when the Play and Show option is switched on.
