Synchronizing Windows

In order to analyze and efficiently compare different versions of the same sound material, you can synchronize the displayed windows. The full synchronization (provided by default when you start a new session with DART XP Pro) guarantees that all changes in display features made in the active soundfile window (position of the cursor, time zoom, volume zoom, offset, left/right channel selection, marker locations, file info), will be automatically extended to other windows shown on the screen.

If you want to select custom features to be synchronized or to disable synchronization, choose the appropriate option using the Synchronization dialog box accessible from the Window menu.

When convenient you can switch the synchronization on (Full) or off (None) by pressing the SYNCHRONIZE button, situated on the toolbar. However, the Synchronization dialog allowing you to select custom features due to be synchronized (Custom) is available only from the Window menu.

Time synchronization

Comparing the resampled audio signal with its original version is a bit tricky - since both files differ in length, the 'ordinary' synchronization, which does not take into account the sampling rates of displayed files, will fail to locate fragments of the recordings with the identical contents. To help you compare several variants of the recording with different sampling rates a special time synchronization feature was added to the Preferences dialog available from the Options menu. When the Time sync box is checked and the synchronization is switched on, the cursors in all displayed windows are automatically time-aligned. This means that if the Play local command is used, the same portion of the audio material will be played back irrespective of the corresponding sampling rates. Similarly, when a block of samples is selected in an active window the appropriately scaled (contracted or extended) blocks will be marked in the remaining windows.

NOTICE

When the time synchronization is on and the compared files have different sampling rates, the time-aligned cursors have different relative positions within each window (unless placed exactly in the center of an active window). To put them exactly one over another, i.e. along the same vertical line, press the TAB key.
