About sonowareCore

About sonowareCore

Our software is designed to achieve maximum flexibility by still keeping the performance (i.e. latency and processing load) as low as possible. Highly optimized algorithms ensure that.

This makes it easy to customize our software to just what you need without a hassle. This prevents costly computational overheads and ensures that our software runs perfectly on your platform. Our core algorithms are programmed in C and thus run on virtually anything.

Depending on your application, we ship apps, libs or source code.

Signal Flow Design

Signal Flow Design

Powered by our in-house graphical signal flow design tools, we quickly combine our as well as third-party digital signal processing modules to a signal flow that exactly fits your needs.

Signal Flow Design

High-performance

All signal processing algorithms are implemented in plain C99, having in mind compilers and their vectorization features as well as platforms such as ARM and x86 with their instruction sets.

Our automated code generation and optimization tools provide up to another 30% performance gain. Please contact us for more details.

Flexible & modular

Our software is exceptionally modular which makes it very flexible. All modules are designed to fit in multiple applications and can easily be combined to arbitrary signal flows.

About sonowareUI

About sonowareUI

In every signal processing system there are hundreds or even thousands of parameters that can be adjusted for optimal performance of the algorithms. Managing these parameters and evaluating their effect on the output of the system can be a tedious effort.

With sonowareUI this can be done effortlessly and in real-time. In addition to that, we have integrated a plethora of useful features and tools to make sonowareUI a real powerhouse for tuning signal processing systems.

About sonowareUI

Full control in real-time

sonowareUI connects to all signal processing solutions offered by sonoware. Change all parameters of the system via an intuitive and clean interface in real-time and directly observe the influence on the system performance.

All changes in the signal processing system are automatically synchronized with each instance of sonowareUI connected, so you are always up to date.

Connectivity

No matter if the signal processing core is running on an embedded system with limited I/O or a fully-fledged SoC the underlying communication interface will handle all situations and enable the use of sonowareUI for almost every platform.

Record and listen

You need to record some data for later evaluation or offline-analysis? No problem, with the built-in recording feature sonowareUI lets you stream and record all time-domain signals to the system running sonowareUI.

You are running sonowareUI from a different room or even from a different country entirely and need to evaluate the performance of the system? We got you covered! sonowareUI also enables you to listen to any signal in real-time.

Documentation built-in

Whenever you are unsure about the effect of a parameter, simply double-click on the widget in sonowareUI to access the built-in documentation for all sonoware signal processing modules.

This will make you an expert in tuning audio systems in no time.

Favorites

Often you need to adjust the same set of parameter over and over again. There is no need to memorize all the relevant parameters and jump between different modules. Just use the favorites feature to create your own customized selection of parameters into a single tab - even from different modules across the system.

History

After a long tuning session it might be hard to remember all adjustments made to the system. With the detailed history feature of sonowareUI you can easily scroll through a log of all changes made to the system in the current session.

But that’s not all! You can also create snapshots to return to a specific tuning state that you liked.

Integrated tools

All features above already make sonowareUI an absolute powerhouse to fine-tune any signal processing system. But we didn’t stop there. Follow the links below to explore all advanced tools that are also integrated into sonowareUI.

Real-time Plots

Pictures speak louder than words

This is not only true for a lot of situations but also for fine-tuning speech and audio signal processing algorithms. With our advanced real-time plotting engine you can quickly have a look at all internal signals of a signal processing suite while adjusting parameters and listening to the output.

Diagnosis

Need to fulfill a lot of technical requirements? Automated diagnosis and testing to the rescue.

sonoware’s automated diagnosis and self-testing framework allows you to run any series of complex measurements and analyses automatically or in an assisted manner to help your engineers integrate sonoware products into your workflows and procedures and to detect regressions or incompatibilities early on.

Further, sonoware on-line tests ensure that (audio hardware) failures are detected immediately during regular system operation, so you can easily react to them.

IR Analysis

Automatically analyze room acoustics from an impulse response measurement

The room acoustics are of high importance for any audio system. In order to easily analyze acoustic paths between loudspeakers and microphones in a room, we have integrated automated analytics right into sonowareUI.

Beamforming

Focus on what matters most
Beamforming

A standard single microphone is not able to separate the desired signal, which is often a speaking person, from disturbing sounds. The human being is able to filter out undesired sounds and concentrate on a single sound source - a phenomenon known as the cocktail party effect. A microphone is constantly listening to everything and picks up sound from all directions.

This problem can be solved by combining multiple microphones to make this array “listen” into a configurable direction. This technique is called beamforming. Record just what you want to hear and block all disturbing sounds.

Beamforming

How does it work?

How does it work?

Using multiple microphones enables the beamforming software to estimate the direction of any given sound by making use of the different times of arrival at the individual microphones.

sonoware offers several design methods to control the direction and width of the beam the microphone array is listening to, including:

  • Modal subspace decomposition (MSD)
  • Minimum variance distortionless response (MVDR)
  • Minimum power distortionless response (MPDR)

Of course the design is integrated into our universal UI, check it out!

Applications

We offer our beamforming solutions as a standalone software as well as integrated into all of our signal processing suites. No matter if you want to block disturbing background noise in the car to optimize the recorded signal of the passengers or you want to focus on a speaker in a noisy operating room or you need a clean speech signal for speech recognition - beamforming solutions by sonoware will get you there fast and easily.

Please follow the links to the side to find out more about our various applications of beamforming solutions.
