Noise that reacts to the player and the room.
A major challenge in the design of digital pianos is reproducing the natural sound of an acoustic piano.
The quality of the experience goes beyond that of the piano samples or the strength of the speakers; it is influenced by the way the pianist plays, by the dynamics of the performance, by the acoustics of the room, and by the level at which the sound is being heard.
Blitz's sound technology is D.A.S. (Dynamic Adaptive Sound), and it has been designed so as to combine these elements. It achieves this by analyzing them and making real-time adjustments to the output, thus providing a more natural, balanced and accurate piano sound.
The objective is simply to produce a sound as if it is coming directly from the instrument, with that sense of presence and coherence which makes playing seem natural.
Why D.A.S.?
The natural sound of a piano is just as much a matter of how we hear it as it is of how it is reproduced.
The response of human hearing to various frequencies changes with variations in volume, so raising or lowering the sound of a piano can modify the way its tone is perceived and its character.
It is particularly important in the case of the piano, since each note includes the fundamental frequency, the harmonics, the attack transients, the resonances, and the expressive nuances of the way the player touches the keys.
D.A.S. considers human hearing and the actual conditions under which instruments are played in order to help maintain tonal balance and detail at all volume levels.
The piano must keep its character when playing at low volumes and at higher volumes it must maintain both its clarity and balance.
How It Works
The D.A.S. constantly analyzes the data as it comes in and makes real-time adjustments to the sound processing in order to match the performance and the acoustic conditions.
It takes several factors into account:
- The strength and character of the player’s touch
- Playing style and musical dynamics
- The acoustics of the surrounding space
- The selected volume level
The system enables a clearer, more balanced, and more natural sound by improving the output and getting rid of the unwanted noise.
D.A.S. does not simply provide a preset sound setting; instead, its adaptive method takes account of the conditions under which the piano is played and heard.
From Key to Ear
The way in which you play a digital piano is determined by all the parts of the instrument functioning in unison.
From the time that a key is pressed until the sound reaches the pianist, the performance details and the acoustic conditions have an effect on the outcome.
The D.A.S. signal path
- Pianist
- Keyboard and performance data
- Digital processing and analysis
- D.A.S.
- Sound optimization and noise removal
- Amplification
- Speaker system
- The pianist’s ears
In this system D.A.S. handles the relationship between the way the player touches the device, the acoustic environment, and the sound which finally reaches the listener.
Sound That Adapts to Your Setting
Each room has its own acoustic properties and each pianist plays the piano in their own way.
The D.A.S. explains these differences by adjusting the sound output in response to the conditions encountered.
What it aims to achieve is to ensure that the listening experience remains balanced, whether you are practicing in a quiet manner or performing with all the power and expression.
Designed Around Human Hearing
A fundamental principle of hearing science is illustrated by equal-loudness contours, which display the way the ear's sensitivity to various frequencies varies with sound level.
D.A.S. takes advantage of the natural way in which humans hear, ensuring that the piano maintains its apparent tonal balance as the volume changes.
In short, the D.A.S. takes into account both the sound that the system generates and the sound that the pianist actually hears.
A Difference You Can Feel as You Play
It gains its position through the way in which it is played.
In the more delicate sections the piano must stay clear, rich in tone, and full in character. It should keep its energy and depth but at the same time maintain clarity and tonal balance.
The instrument should remain natural and cohesive as both the performance and the listening volume change.
The role of D.A.S. is to convey to the listener a realistic impression of the piano—an audible presence that one feels as if it comes directly from the instrument.
