Name: SIS II
Specialized Audio Editor
New interface. New capabilities.
The new SIS II includes powerful tools for speech signal analysis, enhanced speech visualization, display
and analysis capabilities, induding speech segmentation and text transcription. and many other features.
Forensicanalysis of audio recordings is faster and easier with the SIS II.

Working with Spectrum Filters
Easy Text Transcription and Export
One of three filters (mverse, harmonic and spectrum-saving)
can be created and applied to the slgnal spectrum, modifying
its shape accordingly (e.g. to enhance speech, Improve clarity,
remow tonal notses, etc.). Filter processing a important in
nolse filtering and tdent~fication.
Selected fragments can be easlly assigned to particular
categories (e.g. d~fferentspeakers or sounds) and speech
fragments can be displayed as corresponding text. Thts output
can be exported to Word as a text document.
Work with Layers and Transparency
Easy Signal Navigation
Signals can be layered for easy comparison. Colon and
transparency can be changed to ease readabilrty
The functronal waveform navrgatlonbar lets you see the entlre
signal. The area being analyzed is displayed In the waveform
navrgation window. This can be changed easily by selectrng
another section for display.

Working with Projects
Create projects and add related flles (audio, video, text).
Open project flles from the SIS I1 interface.
Optimal Window Arrangement
Signal wrndows are arranged conveniently accordrng to task
vertical for rdentification, honzontalfar authentication and norse
filtenng, or customized according to user preference.
Quick Text Search
