Liberty Interview Recorder
Digital Audio/Video Police Forensic Interview Recorder
The Liberty Interview Recorder is a simple, easy to use recording system that captures forensic interview and interrogation audio, video and notes for police, law enforcement services and other government agencies.
How does it work?
The program uses standard VHS-like Start, Stop and Record buttons. The recorded material is saved into a single file on the recording system hard-drive. Optionally, the file may be automatically and simultaneously recorded to a secure file server and saved onto a CD/DVD. The recordings can later be transcribed or provided to other agencies in a universal playback format.
The recorded notes serve as “bookmarks” or cue points into the recording file. The notes may later be searched to find and identify recordings files. They also eliminate the need to fast-forward or rewind through large recording files.

Supports multi-camera recording
The Liberty Interview Recorder supports multi-camera recording. Multi-camera recording means that the Liberty system captures and records multiple complete video feeds for each recording session, instead of doing a more traditional picture-in-a-picture overlay. Multi-camera support is critical for applications where users want to capture two complete streams of video. This can be especially important when recording a close view of the subject and a wide-angle view of an entire room. Or for child advocate or adolescent interviews where the subject may move around. The older picture-in-a-picture type solution uses an overlay technique where a portion of the recording stream may be overlaid by a second camera feed, thus obscuring the primary camera and degrading the resulting video.

Save audio/video recordings into standard PDF files with cue Points and annotations
Audio/Video recordings may be saved into standard PDF documents. Annotations can provide cue points into the recordings and playback is facilitated through Windows Media Player. A proprietary playback program is not required.
Bookmarks provide multiple cue points to where the operator may instantaneously jump the audio / video playback.
The Liberty Interview Recorder integrates with the Liberty Evidence Management System and the Post Recording Manager for a complete and secure file management system.
The Liberty Player for Windows
The Liberty Player provides playback facilities for your captured audio files. The Liberty Interview Player is available as a no cost download. The Player lets you select and listen to individual channels in a recording or a mix of several or all of the channels. The Player runs on PCs with Windows that have standard audio capabilities. An optional foot pedal for controlling playback is available.
