Compression

Note: Using compression settings may decrease graphic performance while scrolling through waveforms.

Using high compression factors while browsing large synchronized files with the Navigator could cause a slow response on-screen. Scrolling rate is based on the last waveform file in focus.

Example: Waveform File A is fully compressed at a compression factor of 100; Waveform File B has no compression factor applied (compression factor of 1). If you click on Waveform File A then scroll one pixel at a time (using one of the arrow keys on the Navigator), Waveform File B will move 100 pixels per click. If you click on Waveform File B then scroll one pixel at a time (using one of the arrow keys on the Navigator), Waveform File A will move 1/100th pixel (i.e., it will not move for about 100 clicks - depending on the exact location of the cursor).

Un-Check the Continuous Scrolling preference to increase performance. The tradeoff is that you will not see the waveform files scroll.

Check the Show exact Time in compressed waveform(s) preference to continually update the time display in compressed waveform files. If this preference is turned off, the display in the annotation of the waveform file will not update until the number of samples (based on the compression factor) is passed (i.e., when the cursor in the waveform file actually moves).
