CLIPPER

CLIPPER is JAGUAR's built-in sound editor that can be used to create audio clips from wideband recordings.

When you have the relevant audio material in the CLIPPER window, you can play/edit/process the clip before saving it (see the options below). The clip name is of the standard JAGUAR format unless you have defined your own clip name format in SETTINGS > PLAYBACK > CLIPNAME. The clip name is displayed on the bottom of the CLIPPER window, and this name can be edited. But do not change the WAV/MP3 suffix here, go to CLIPPER > FORMAT to do that.

HOW TO

KEY = C

CLIPPER can be started during the playback by pressing the "C" key, or by clicking the TOOLBAR > SCISSORS icon, or from STATION MENU > CLIPPER. Another press or click on the relevant key/icon/menu will stop the flow of the audible sound to the CLIPPER editor window. You can also click STOP on the CLIPPER menu. If you want, you can add more than one segment of audio to the same clip, using any of the ways described above to start CLIPPER.

You can play the audio clip by clicking on PLAY in the menu, or by clicking the waveform in the editor window at any position. You can also highlight an area in the waveform to limit the playback or editing to that specific area. Clicking the waveform outside the highlighted area will remove the highlight. If you edit the waveform without highlighting any particular area, the entire audio clip will be subject to these edits.

The CLIPPER menu contains the following options:

• FORMAT: Select the audio clip format (WAV | MP3). Note: FILEMAIL clips are always sent as MP3.

• RESTORE: Cancel all edits you have made and restore the original audio clip.

• UNDO: Undo the last edit.

• FADE: Standard fade function.

• VOLUME+: Increase the amplitude.

• VOLUME-: Decrease the amplitude.

• COPY>TAIL: Copy the highlighted area to the end of the clip.

• CROP: Keep the highlighted area, delete the rest.

• CUT: Delete the highlighted area.

When you have finalized your edits, you have the following save options in the menu:

• SAVE AS: Select the save folder manually. While saving, you can still change the clip file name.

• SAVE: Save your clip to the CLIPS folder in your JAGUAR folder.

• SEND>FILEMAIL: Send the clip to your another JAGUAR PC.

• PLAY: Play the audio clip / highlighted area.

• TEMPO and PITCH: Extra options for modifying the tempo and pitch of the audio. These buttons are not available by default. See more information about these on the bottom.

CLIPPER contains also a precision tool for bit fiddlers to get the maximum out of the audio:

• If an audio area has been highlighted in CLIPPER, it can be zoomed in, even to the sample level. Use the mouse wheel or the left/right arrow keys to switch between FULL AREA, RED AREA, and GREEN AREA.

• The GREEN area is the lowest level. You can move the mouse and position the area to the desired audio peak: first, click once to lock the position, then increase or decrease the width of the GREEN area with the mouse wheel or the left/right arrow keys.

• You can use the FADE button to eliminate "runaway peaks" (= fade in/ fade out for the RED and GREEN areas)

• The GREEN area is actually a low-level sample microscope. It supports sample correction on individual samples, i.e. FADE is applicable even to one single sample in the audio, which can be useful in eliminating harmful clicks if JAGUAR's default internal CLICK REMOVER (CR) consumes useful audio too much.

You can close CLIPPER by clicking EXIT or by right-clicking the CLIPPER window.

Modifying the audio by changing tempo and/or pitch may help in some tough IDs. These functions use the 3rd party audio library called "SoundTouch" (http://surina.net/soundtouch/index.html ).

Note that changing tempo does not change the pitch and changing pitch does not change tempo, but if you necessarily want, you can change both of them (in that case you get the classic "chipmunk/klingon" effect just as when changing the plain audio playback sampling rate.

How to use TEMPO and PITCH functions in JAGUAR:

• TEMPO and PITCH buttons are available in the CLIPPER only if a program called "soundstretch.exe" is downloaded and available in the JAGUAR installation folder.

• You can download Soundstretch via JAGUAR's download page http://jaguars.kapsi.fi/download > OPTIONAL FILES > SOUNDSTRETCH.zip) or directly from http://surina.net/soundtouch/download.html : select "SoundStretch 2.1.1 for Windows". Unzip the package contents to your JAGUAR installation folder.

• Changing tempo/pitch can be done by clicking TEMPO/PITCH buttons (< for decrease, > for increase) or using the "JAGUAR style": use mouse wheel and or left/right arrow buttons whenever the mouse cursor is over either of these buttons.

• Playback starts automatically after you have changed tempo/pitch. Note that any change targets the whole clip (can't be used for painted areas) and the playback is done outside CLIPPER (the output can't be saved). However the last used "external audio file" is saved as CLIPS\TEMP2.WAV.

• The stepping/scale of the values differ a bit from the original (in JAGUAR "TEMPO 5.0" means 50% increase for the tempo), otherwise the operation should be easy and intuitive.

You can also extract and record the audio by pressing ALT-C: this mode does not start the GUI (there's only "RECORDING AUDIO" text visible on the STATUSBAR when this mode is active). This mode will record ANY audio you will currently hear on the headphones: it can be the Jaguar audio, the Perseus audio, the internet stream played within or outside Jaguar, Youtube video, etc. This recording ends when you press ALT-C again, then you can save the audio clip in the mp3 format.

NOTE: Some Windows setups do not support this feature.
