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.
