Main Features

1. This acoustic simulation software combines the essential elements of Yamaha Professional Audio acoustic technology for all sound handled from input to output, including DSP, amps, speakers, and even the venue's design.
2. The software provides superb accuracy and reliability thanks to the knowledge and experience of the Yamaha Center for Advanced Sound Technologies, which is at the forefront of the world's acoustic technology with its Active Field Control and Acoustic Modeling, and has employed its advanced acoustic technology in the acoustic design of many concert halls.
3. With sophisticated graphic user interface and user-friendly settings wizard, simulation can be performed precisely and easily.
4. You can easily set and change the venue shape, conditions, and other aspects with the wizard, and make graphical visualizations of sound pressure level distribution at receiving points, frequency characteristics graphs, and contour figures. Plus it provides auralization, which lets you hear the sound with your ears using any sound source for even better monitoring.
5. The built-in Yamaha Speaker "Installation Series" library makes it easy to use with the Yamaha Power Amplifier Tn series, PC-N series, XP series, DME64N, DME24N, DME8o, DME4io Digital Mixing Engines and the SP2060 Speaker Processor to facilitate total acoustic system planning.
6. You can generate DDF and DAF data for exporting simulation results to DME64N, DME24N, DME8o, DME4io and SP2060. You can put the simulation result to use in your actual system setup quickly and with little effort.
7. Convenient features such as the auto layout of array speakers and auto setting of speaker parameters are included to conduct the important tasks of speaker selection, positioning, and setting of speaker array.
8. The Yamaha Sound System Simulator is free software that can be downloaded from this web site.

Procedure of Use

STEP 1:

1) Select the Venue Geometry for Calculation.

Select from five Venue Templates: Rectangular, Fan, Circle, Cross, and Polygon. The chosen geometry is displayed in 3D. The receiving point is usually the height of the listeners' ears. Select the height from the floor to the receiving surface from the list box.

2) Use Floor Edit to better determine the shape of the simulation venue.

Floor Edit is performed for the horizontal floor plans and vertical cross sections with the mouse. Units for measurements can be selected from feet or meters.

Zoom

3) Open "Project Properties" under the "file" menu.

Select the "Calculation" tab.  Here, configure simulation settings such as "humidity, temperature, calculation precision, phase consideration, etc.
Also select "system" and "others" tabs to configure further system settings and details.

Zoom

STEP 2:

1) Set the speaker array.

You can choose manual or automatic layout of speaker array(s).  You may also choose to add distributed speaker systems by clicking the menu on the upper right hand side.

Choose the speaker array from the list and install the speakers in the desired positions.  Yamaha Installation Series speakers are preset in the library and ca be selected easily. Then set position, tilt, pan, rotate, splay angle, and symmetry for the selected speaker array or system.

Zoom

2) Set various conditions for the speaker array.

Simulation begins when you select the speaker array. You can change several conditions for the speaker array in real-time as you view the simulation result to optimize the sound field design.
You can set array, position, tilt, pan, rotate, target point, distance, arrival time, SP properties, and other features.

Zoom

STEP 3:

1) Set output configuration.

The Y-S3 automatically creates the output configurations based on the set speaker system.
They are displayed on the speaker array property configuration screen.  You may check/alter settings such as amplifier input level, delay, PEQ, gain, attenuation, amplifier drive mode, etc.

Zoom

2) Check directivity of speaker array (balloon).

Balloon data (directivity data for each frequency) for the speaker array can be checked on the screen in 3D. Balloon data is displayed for each frequency.

Zoom

STEP 4:

1) Simulation result is displayed with visualized diagrams.

The Y-S3 can visualize the simulation result with instantly understandable diagrams like those below.

• Contour Figure:

A contour figure for -3dB, -6dB and -9dB of 1/1 octave band is displayed in the main window.

Zoom

• Sound Pressure Level Distribution:

Choose SPL mode to display the sound pressure level distribution.
The sound pressure level distribution for selected frequencies and bandwidths can be displayed.

Zoom

• Frequency Characteristics Graph:

The bandwidth on the frequency characteristics graph can be changed to 1/1, 1/3, 1/6, or FFT.

Zoom

2) Check simulation results with your ears through auralization.

Y-S3 Not only provides visualization of simulation, but also lets you check the direct sound simulation result with your ears using a pre-recorded dry sound source.  Comparative listening from multiple receiving points can also be performed.

Procedure: Save frequency response at current listening point by selecting memory slot ("No. 1 to 8") and then press "Store".  Then press "Info" button.

Zoom

STEP 5:

1) Save the configuration in DME format.

Y-S3 automatically generates an output configuration for all speaker systems that are installed, and saves it in the format of DME Designer, the application software for DME control. 
If you use the Yamaha Digital Mixing Engine DME64N, DME24N, DME8o, DME4io or SP2060 as a speaker processor, you can efficiently construct a sound system with greater accuracy and minimal effort.

2) Generate a project report.

Y-S3 can generate a complete report of simulated results and system configurations in one HTML file.
