The Edit Menu

WARNING: The Snoori signal editor is designed purposely for fine editing of speech signals more so than for editing long speech segments. This explains why the maximum duration of a speech signal visualized by WinSnoori is limited to 4 seconds. WinSnoori has at its disposal a buffer where to keep possible modifications of the signal sending them to a speech file when necessary, i.e., during movements or during the insertion of the WinSnoori clipboard or of a sufficiently big file. In such cases, Snoori asks whether or not to save the modifications.

A remark: During operations which do not preserve the periodic nature of the speech signal (e.g., “cut “ operation), a vertical bar appears on the spectrogram. To restore the periodic structure, it generally suffices to cut out a whole period of the signal or to damp or attenuate to a sufficient degree the point presenting some discontinuity.

The present menu is accessible only after the opening of a speech file. The left button of the mouse helps to demarcate a zone of the displayed spectrogram. The new zone called a ”highlighted region” appears in a new Color (in the spectro or speech window).

The clipboard used is a WinSnoori incorporated clipboard which is in no way related to the WINDOWS clipboard.

The menu commands

Cancel: Cancel the last executed command among the list: copy, cut, paste, erase, attenuate left, attenuate right and filter.

Cut: Cut and place the highlighted region in the clipboard.

Copy: Make a copy of the highlighted region in the clipboard.

Paste: Paste the clipboard in front of the highlighted region.

Delete: Erase the highlighted region.

Editing tools: Opens the window that controls the advanced editing facilities of WinSnoori.: Damping, FIR filters, OLA filters, Noise addition. See this description for further details.

Resampling: Resample audio files.

Play: Allows the operator to listen once to the speech signal in the highlighted region

Play many: Allows the operator to listen several times to the speech signal in the highlighted region.

Play the file: This function plays the whole file back.

Zoom in: Zooms on the signal making the highlighted region to be displayed on the entire main window.

Zoom out: Suppress the zoom and display a 2 second portion of the speech signal.

Go to: Helps to skim through the speech file. The user indicates the first millisecond of the portion to display.

Frequency: To specify the sampling frequency used for play-back. Since this frequency is used in several Snoori modules, it is important not forget to reset it to its normal value after listening to the speech signal under examination at frequencies other than its own frequency.

Copy to clipboard: Copy the signal (without the time scale below the signal) to the clipboard. The clipboard can be accessed through Paint for instance.
