Local cutting of an unwanted audio material may be an efficient tool for elimination of disturbances. If the removed fragment is sufficiently short and the signal on its right hand side is a “natural continuation” of the one observed on its left hand side, our auditory system can be easily fooled - the disturbance is lost without a trace.
Smart cut is a tool which is capable of localizing such “natural continuations” by itself, saving a lot of time and efforts.
To use Smart cut proceed as follows:
1. Select a block containing this part of a signal you would like to eliminate. If a signal has strong periodic components, try to make the block width commensurate with the signal period or its multiplicity.
2. Evoke the Smart cut dialog, by choosing the Smart cut command from the Toolbox menu.
3. Adjust the left and/or right block edges position (the search is limited to 500 ms on the left and right side of each block edge). When you decide to move the right block boundary to the left or right
of its current position, the signal just preceding the left block boundary will serve as a reference and vice versa. Use the Accuracy setting to increase or decrease accuracy of the fit.
4. Press the Preview button to evaluate the results. The audio file will remain unmodified at this stage of processing - the selected signal samples are simply skipped during the playback (virtual cutting). Use the Preferences dialog, available from the Options menu, to change the local audition time, if necessary.
5. If the results are satisfactory, press the Process button, otherwise return to Step 3 above and try to differently position block edges. Please note that, for long recordings, cutting may be a very time consuming operation as it involves rewriting the entire audio file.
At any time you can reduce the size of the Smart cut dialog by pressing the MINIMIZE
button situated in its upper right corner. The reduced size dialog contains the search forward/backward, preview and close buttons only. Use the MAXIMIZE
button to switch back to the full size dialog.
NOTICE
You can leave the Smart cut dialog without closing it to select an entirely new block or to adjust the boundaries of an existing block.
