MXS – motion eXperience Synthesizer
The core of MX Suite is MXS, the Motion eXperience Synthesizer. This is an ultra-compact hardware for creation and delivery of analog active sound & vibration signals.
It reads vehicle performance data (Speed, Engine load, etc.) via CANbus and/or other wireless interfaces. Special algorithms create natural sounding audio signals in complete consistency with the original vehicle noise and driver interactivity.
The simulation database and initial tuning is provided by the desktop application MX Designer. Online fine-tuning design can be done via WiFi using the iOS based tablet application MX AirGo.
The hardware is based on a powerful single-board computer platform. Running an optimized embedded Linux operating system provides extra short boot times and extraordinary good performance, stability, and reliability.
The clearly structured arrangement of user interfaces solely provides what is needed for keeping the in-vehicle installation tidy and uncluttered. The single components include:
|– 8 output / 6 input audio channels (standard RCA connectors, line levels, CS42448 audio codec),|
|– Highspeed CANbus network ( standard D-Sub 9 pin, MCP2515 CAN controller),|
|– Lockable USB Type-C power connector (5.1V / 3.0A DC),||– Gigabit Ethernet,|
|– Status LEDs for CANbus activity, simulation status, and power supply.|
Finally some benchmark data demonstrate how powerful the MXS hardware performs:
|– Quad core Cortex-A72, 1.5 GHz,|
|– 4 GB LPDDR4-3200 SDRAM,|
|– 2.4 GHz and 5.0 GHz IEEE 802.11ac wireless,|
|– 32 GB disk,|
MX Designer is a cross-platform desktop application (Windows, MacOS) responsible for administrating the MXS design projects and working on the design basics in a studio or office environment.
Intuitive user-interfaces allow to create convincing vehicle sound designs in a straight-forward manner.
The user can switch between two different application modes. In Edit mode all the basic parameters are set up. A broad choice of different sound synthesizing sources (Events, Loops, Harmonics, FM stacks, …) build the basis for a rich color of sound. All these sound objects can be modulated by a pool of sound effects (Volume control, GrainCaster, standard filters, …). Both sound sources and the assigned filtering effects can be connected to the vehicle performance data and driver actions in a most flexible way. Additionally all sorts of triggering logic are available, i.e. the activation of the individual sounds can follow certain parameters like engine status, gear selection, speed range, and many more. This allows the sound design to naturally follow the current status of the moving object and the behaviour of the „user“.
Once the basic setup is completed the project database is comfortably transmitted to the MXS hardware via network connection. After re-initialization of the rendering software Tuning mode can be activated. This allows to control almost all of the simulation parameters in real-time. At this moment the design process turns into an interactive experience where changing sound settings can directly be felt immediately after application. The generated new online designs can finally be saved into the MX Designer database and be used as the starting point for subsequent design sessions.
Another important feature of MX Designer is the flexible assignment of the vehicle CANbus specification to the control parameters used during simulation. Import and Export of setups allow easy re-use of previously done work.
A valuable time-saving capability is the monitoring of various simulation-relevant properties on the MXS hardware. Being able to display parameters like software status, CANbus activity, etc. eliminates the black box character of most DSP-based systems. This transparency helps to quickly detect most of the causes for usual maloperation situations.
MX AirGo is the mobile application used for fine-tuning of the developed designs on the road in the target vehicle. Furthermore its intended application is for final evaluation by decision makers and probands in product test series.
MX AirGo is developed for the iOS environment (iPad or iPad Mini) and can be downloaded directly from the Apple AppStore.
Via WiFi it connects to the MXS device and instantaneously the current tuning set parameters and data are received and ready for user evaluations and modifications.
In real-time all tuning parameters can be changed via an intuitive user interface. This provides an interactive way to experience how the changes of the synthesized sounds contribute to the overall product experience.
The user can switch between the 9 different data sets and evaluate how good the different designs apply to the target system.
Additionally MX AirGo allows to observe the current operation status of the MXS hardware system.
|– CANbus data arriving from the target vehicle,|
|– Hardware performance like CPU & memory load,|
|– Output & input sound levels available at the analog audio connectors,|
MX Driver simulates the driving parameters present on the CANbus of the target vehicle. It enables the user to interactively experience the sound designs with the minimum amount of hardware setup when doing design work in the studio/office location. A standard CAN Interface for USB (Peak-System PCAN-USB ) connects the desktop machine and the MXS rendering synthesizer.
Two ways of controlling the vehicle parameters in real-time are available:
Standard sliders and dials supported by editable text boxes allow detailed adjustments of performance data.
Standard consumer MIDI devices can be used to control the driving behaviour of the simulation. This provides an even more natural interface which allows to adjust multiple parameters simultaneously.
