Hyundai Ioniq 5N Active Sound, powered by neosonic Sound Designer

World Performance Car of the Year 2024

Top Gear Car of the Year 2023

High Performance electric race car with full combustion sound performance

This active sound development project was both a welcome challenge and a lot of fun, as high performance electric vehicles allow us to once again push the envelope to extend capabilities and impact of automotive Active Sound Design. 

The 650 PS Hyundai Ioniq 5 N has already redefined the state of the art in Active Sound, introducing a wealth of industry-first sound features that create the amazingly realistic sound scape of a combustion racing car, pushing EV performance driving to an entirely new level. 

The Press: “With doubts I get into the Hyundai 5N, with damp trousers from the tears of joy in the bucket seat I fall out again later.  

Biggest surprise: How the N Active Sound+ simulates the sonorous hum of a hot driving machine, depending on the accelerator pedal position or speed, plus the minimal shift stroke of a transmission. And how seriously this comes across

On paper you think: Dispensible gimmick. In reality you think: cool!”

 Autozeitung and CAR Mag 

We drive off: Directly in N-Mode, switching to manual mode and injection sound. Hardcore: Because of the generated engine sounds you really think you’re sitting in an i30 N. The sonorous sound of the combustion engine and the flap exhaust, the gear shift warning flashing at 8000 rpm, the babbling, the engine sputtering when quickly downshifting with double-declutching – mind-boggling in an Electric Vehicle, acoustically very convincing.”

Sound Designer Suite

Sound Designer is a gorgeous sounding modular active sound design development environment. It covers all aspects of active sound design creation and provides a versatile range of real-world templates to immediately start working from. 

Prototype your first sound signature within the first hour. Drive it in a simulator or car within the second hour.

Sound Designer comes complete with everything you need to deliver convincing active sound designs for cars and ready them for mass production in a streamlined process. Choose from order-based and granular sound synthesis algorithms. Beef up your sound signatures with frequency modulation (FM) synthesis, pitched sound file playback, or a noise generator. Activate a shepard module and throw in some iir / fir filters and effects processing for good measure.

Create and perfect your sound in real-time with instant sonic feedback throughout.

Use the included vehicle data playback module to drive your sound with real-world measurements from Simcenter Testlab LDSFs, vehicle data embedded in standard wave files. Generate driving data with function curves quickly jotted on the screen or simply move speed-, rpm-, torque-sliders with mouse / touch / pen.

Play back a synchronized video of your drive cycle from the driver’s seat or a drive-by shot for a more realistic tuning experience. 

Hook up your PC to a car’s CAN bus with the supplied multi-channel CAN interface. Dump your sound signatures to the supplied prototyping ECU or to a supported Tier1 ECU. Immediately drive your sounds in the lab or car and perform real-time vehicle-level tuning. It is that simple. 

Sound Designer has been developed by automotive sound designers for automotive sound designers.

ASD easy as 1-2-3

1. on the pc choose one of the provided sound signature templates

2. tweak the template, fill in your own audio content such as samples, and drive in the lab with the internal vehicle data generator / game wheel / a connected drive simulator like the directly supported VI-Grade NVH sim

3. seamlessly continue tuning and validating in a vehicle on the PC or a supported ECU


jumpstart from templates

Sound Designer comes with a host of ready-to-use templates. 

The supplied templates cover the most common use-cases in active sound design for EVs, ICEs, and PHEVs. Their signal chains range from the most simple 1-layer to more complex 4-layer layouts to have you covered for all kinds of design tasks. Sound signatures are defined by the signal chain which is the selection and arrangement of processing modules. Loading a new signature will also load a new signal chain which can be entirely different. This makes Sound Designer extremely flexible. 

A special section of templates is devoted to AVAS sounds to get you up and running with sound design for AVAS in no time. AVAS sound signatures run on the PC or on the supplied AVAS ECU which is ready for mass-production.

The Advanced signatures section sports more complex templates with feedback sounds, FIR filters, and other special features. 

efficient work flows

Harvest neosonic’s vast experience in automotive sound design which has been built into the Sound Designer’s straight work flow. 

Start from a template on the PC. Try different source samples, massage them with driving data from the CAN generation module. Tweak parameters like pitch, volume, filter frequencies in real-time during playback. Save your result as a named preset. Dump it to an external sound generation hardware unit such as the provided or a third party ECU. 

Plug the ECU into a vehicle and continue tuning using the same editor software throughout the process. 

All changes whether made on an ECU or the PC are 1:1 compatible with all supported platforms, making the seamless transition between platforms a reality. 


realtime tuning, assignable vehicle signals, virtual gearshifts

All parameter editing in Sound Designer is strictly real-time to speed up the process of sound creation and tuning to the maximum. 

Designing great vehicle sounds needs a good idea plus honing it to perfection. This can only be achieved with a real-time tool as it couples the designer to the sound in a tight loop. No cumbersome value setting and verification, you just tweak parameters while the simulated or real vehicle is moving and the sound is being generated. This high-speed approach doubles the sound quality while cutting development time in half, at least.

Freely assign a physical vehicle signal such as rpm, vehicle speed, engine torque, accelerator pedal to audio parameters by simply selecting it from a pop-up menu as shown. 

In addition to physical vehicle signals Sound Designer can also generate virtual control signals internally which combine physical signals or add logic / arithmetic operations to signals to e.g. generate virtual gearshifts when user-defined torque and rpm thresholds are exceeded. 

musical sound quality

With a strong background in music technology and sound design Sound Designer’s sound synthesis, filtering, and audio post-processing algorithms have been carefully crafted to deliver a beautiful, rich sound quality. 

Given Sound Designer’s flexibility to support signal chain layouts from simple to utmost complex, high sound quality will make your vehicle’s interior, exterior, feedback, and AVAS sounds stand apart from the competition. 


design once, deploy on any device

Sound designs made with Sound Designer can be seamlessly deployed on any supported device, including the bundled AD Sharc-based Vehicle Unit ECU. In Sound Designer simply choose an output device, dump your sound signature, and continue tuning where you left off on the PC. 

Supported devices range from standard Windows PCs to the most widely used automotive chip sets such as several AD Sharc DSPs, TI J6, Dirana, ARM

The range of supported platforms is continuously expanded. Inquire us about support of your target platform. 


specify your custom signal flow

The range of supplied templates isn’t enough for your specialized requirements and ideas? 

Looking for a different routing of CAN signals, more filters, more layers of various sound synthesis algorithms, effects processors in parallel or chained on some but not all signals? Or less of everything to spare dsp cycles and reduce memory footprint?

No problem due to Sound Designer’s modular architecture. Simply specify your audio and control signal flow and we will quickly provide your one-of-a-kind custom signal chain template

Quick turnarounds, ready to use, no headaches. 

VI-Grade NVH simulator Integration

The Sound Designer has been integrated to work directly with the VI-Grade NVH simulator on the same computer without any external hardware boxes or cables. 

In Sound Designer simply select it as a CAN source from the input menu and choose the VI-Grade audio driver in Sound Designer’s audio devices menu. Sound Designer will then be driven by the VI-Grade’s vehicle data and output its multi-channel audio back to VI-Grade to be mixed with the simulator’s road and wind noise.
