VISUALIZATION
Draw FFT or LPC sonograms, adjust brightness, contrast or normalization. Choose the proper frame size, weighting windows and other parameters on the fly. Or you can use default presets. Use spectrum in the point to overlay formants to comparison more visual. Draw cepstrum for pitch and melodic pattern analysis.
PROCESSING
Forensic Audio Workstation provides a wide variety of expert editing and signal processing tools that improve the intelligibility of recorded speech and prepare audio recordings for further analysis.
TEXT TRANSCRIPTION AND SPEECH SEGMENTATION
Selected audio fragments can be easily assigned to particular categories (e.g. different speakers or sounds) and speech fragments can be transcribed and displayed as text.
MULTI-WINDOW INTERFACE
Multi-window interface makes signal comparison easy. Several audio files and their visual representations can be opened in different windows and positioned according to particular tasks.
SIGNAL COMPARISON
Windows can be connected according to time and spectral domain, which makes measurement easier using vertical and horizontal cursors. Spectrograms are automatically redrawn when parameters are changed and a wide variety of settings ensure optimal clarity.
WORKING WITH PROJECTS
With projects, users can keep all files related to an investigated case together, whether it’s an audio, text, video or photo files. All these files can be opened directly from the software.
DETECTING SPEECH AND NOISES
The speech detector automatically marks speech fragments in the audio signal that are suitable for identification. The module can also be configured to detect noisy areas: dial tones, clipped fragments, and clicks.
SIGNAL ANALYSIS
Forensic Audio Workstation software can automatically calculate various signal characteristics
SPEAKER MARKING
IKAR Lab allows you to automatically detect speech fragments pronounced by two different speakers and to mark them accordingly.
