Tuning a cabin audio system in a business jet is both an art and a science. While the tuning process is rooted in science and data, it requires a highly-skilled and experienced audio systems engineer to effectively tune the audio system.
The founders of ALTO Aviation, Don Hamilton and Steve Scarlata, began their careers tuning new production car models around the world in the 1980s and 1990s, gaining invaluable knowledge and experience. Over the years, they were able to refine the skills to develop the revolutionary ALTO tuning process.
Contrary to popular belief, there is no know turning or slider moving during an audio tuning. A precisely calibrated microphone is used to record acoustic measurements via custom-designed computer software, called the ALTO Measurement Suite. This innovative, proprietary software not only registers and records these measurements, but processes the results based upon the application and intended use by each customer.
A variety of different characteristics can be controlled or created, including frequency response equalization, phase interaction, surround sound processing, dynamics processing, and more. To begin the tuning process, individual measurements of every loudspeaker and subwoofer are recorded. Next, the sonic signature of each seating position is captured for each set of speakers. These measurements allow ALTO to accurately predict what the sound will be at each seating location when all the speakers are playing.
Minute changes in the phase or delay of a speaker can drastically affect the sound in a seat for better or worse. An iterative process is used to find the best sound for the VIP and every seat in the cabin. Finally, the sound processing is implemented via DSP inside the ALTO amplifier.
