Block operations are available from the Block menu on the main menu bar.
Block operations enable you to perform corrections and other tasks on a portion of the wave file rather than on the entire file.
To create a block, drag with the mouse in the main window over the area you want to process. The block will be highlighted in blue, and corrections in the block are indicated by blue vertical line in the correction list.
Note, having selected a block, you can fine-adjust the edges of the block or move the entire block to the left or right by dragging with the mouse.
To cancel a block, click with the mouse anywhere outside the block. Note, to avoid accidentally cancelling a block, hold down the CONTROL key during block adjustment.
To modify the corrections within the block use one of the following three functions.
Remove Corrections removes all corrections from the block.
Re-Scan removes all the existing corrections from the block and re-scans it using the parameters you supply when you select the option.
Super-Scan is the same as re-scan except that it superimposes the new corrections on top of the existing corrections rather than removing them first.
Note: These operations are not possible after digital filtering has been applied (eg the hiss filter). Therefore, make sure you have finished editing corrections before applying any digital filters. Alternatively, you can use the Remove Filtering command to restore the block command capabilities.
There is also a Block command called Cut and Splice. This command removes the entire block from the waveform and cross-fades between the sections immediately before and after the block. The command is named after the customary practice of audio engineers to physically cut a section from an audio tape and then splice the tape back together.
Whenever a block is selected, you can right click the mouse to activate a menu of block options.
