Why Stagetracker FX ?
Amplified Theatre Audio The challenges: Amplified theatre audio leaves audiences feeling less connected to a performance. Voices of the actors do not originate from the performers themselves but from a detached place above or beside the stage. Difficult to tell which actor is actually speaking with many actors on the stage.
Amplified Theatre Audio
Amplified Theatre Audio. . . For many years, creative sound technicians have been striving to achieve audio localization to give the audience a more immersive, realistic experience.
Expectations of audiences have increased Full multi-channel surround sound is now commonplace in movie theatres and even widely adopted in people’s own living rooms. A standard audio system is simply not acceptable anymore. As the line array and digital mixing revolutions are getting behind us, we are convinced that localised, natural sound will become one of the next “big things” in audio. We aim for Stagetracker FX to be at the forefront.

R&D Achievement 1: Tracking People on Stage 2006: First time ever, a commercially available tracking system is launched. Taken into use with great success almost from day one on well known shows round Europe.
R&D Achievements 2: Smoothmove™ algorithm Matrix needed to be able to change delays in realtime without any audible artifacts. Smoothmove™: Proprietary algorithms developed to overcome problems inherent in moving audio sources ”transparently”.
R&D Achievement 3: Pan. Between. Point™ algorithm All audio localisation systems have been set up using a similar principle: Divide the stage area into defined areas or "zones" and then time align all the speakers in the house to the centres of each of these zones. Demands complex calculations. Take days to complete and often resulting in unnatural sounding audio.
R&D Achievement 3: Pan. Between. Point™ algorithm As soon as the performer crosses the border into an adjacent zone, the result is a large and sudden shift in the position of the audio even though the performer only took one step! Listeners may experience speakers suddenly increasing or decreasing in level – or even being turned on or off! Audio perceived to be constantly either behind or ahead of the performer’s actual position.
R&D Achievement 3: Pan. Between. Point™ algorithm Goal 1: To move audio smoothly, naturally, continously. Goal 2: Achieve effective audio localisation quickly. Pb. P: A new concept. Traditionally, audio has been panned between speakers. The V 4 Tracking Engine pans between Points. May be as simple or as complex as the user requires. (e. g. the Width Control). Keeps complete coverage.
R&D Achievement 4: Automatic Mode Take this technology out of the hands of specialists and make it viable for use by sound technicians and touring productions everywhere. Using V 4 Automatic Mode, a few simple distance values are all that is required in order to achieve amazing audio localisation.
R&D Achievement 4: Automatic Mode On-stage Points, depth delay calculations and upstage audio level attenuation are all calculated and entered automatically by the software. Front fills, out fills or balcony delays may be added to the system as required and V 4 will automatically tune the necessary level and delay values relating to the upstage Points for these speakers.

Zone Mode For precise audio localisation For use with distributed sound systems For use on long-running productions or installations Specialist set-up required Set-up can be time-consuming
QLab Show control Recently integrated with the industry standard Qlab show control software from Figure 53 QLab is now the sound effects playback and control component in Stagetracker FX. The way we’re doing this is with a new cue in QLab: The Stagetracker Cue.
QLab Show control •
QLab Show control What does this mean? - This means that you can localize sound effects very fast and easy. Draw a path of where you want the sound to go, and it will go there! - Controlling one audio input in the Stagetracker Matrix, the new Stagetracker Cue can take a sound effect and fly it around onstage or anywhere else in the auditorium, using the Stagetracker Matrix for stunning localization effect. - In addition, the Stagetracker Cue also opens up options for controlling live audio inputs, making it easy to localize live audio from wireless microphones in QLab. At any time, Stagetracker Cues can be fired from QLab to control performers' localization on stage.
Latest development: The V 4 s Stand still detection - The Tag incorporates movement sensors (3 x accellerator sensors). - As soon as a performer on stage is coming to standstill, the Stagetracker FX software locks the position, and moves into a state of just fine adjustments of the position. - Threshold for stand still can be set individually to cover any type of show (and type of actors!).
Latest development: The V 4 s
