Custom DSP Software Development
DSP Calibration Services
Not all DSP/DRC software are created equal. In our testing there are significant sound quality differences
between DSP software products. Our DSP calibration service only use these state-of-the-art DSP/DRC software
packages: Acourate, Audiolense and Focus Fidelity.
Unlike other DSP correction services, we use
advanced mathematical analysis of your speakers and room ratio to calculate the optimum FIR correction (eq)
filter based on psychoacoustics.
Our filters are designed to work in both the frequency and time
domain to restore accurate sound arriving at your ears. Not only direct sound, but sound over time,
specifically at low frequencies. The proof is in listening to superior 3D imaging with smooth and clear
Our DSP calibration service is designed to restore accurate sound at your listening position. We
offer up to 6 FIR correction filters for comparison and fine tuning the result to your personal preference
while achieving accurate sound.
For stereo calibration, send us your REW .mdat file or impulse
files from any one of the state-of-the-art DSP software packages along with your room dimensions for a
quote. A software license for one of the DSP packages is required for the service. These can be purchased
directly from our DSP Partners. For multi-channel and/or multi sub systems, please contact us.
Our DSP calibration service is for computer-based audio systems only.
Convolution Integration Services
Integrate HLConvolver into your software or music server to allow convolution capabilities for you or your
HLConvolver can operate as a standalone application or as a “plugin” on multiple OS
platforms including Windows, Mac OS, Linux, iOS and Android.
HLConvolver is a zero-latency, uniform
partitioned convolver. Provides highly efficient, real-time convolution without the requirement for a fast
computer. An Intel i3 2 GHz processor can effectively convolve audio in real-time.
can be integrated into your application or music server as a “plugin” or as a standalone application. With
loopback, system wide audio and application specific audio can be routed through the convolver.
convolution is performed at 32-bit single point floating precision. If multiple sample rates of the filter
is in a zip file, HLConvolver will select the correct sample rate filter based on the ‘hosts” sample rate.
If no suitable filter is found, HLConvolver will use the one most applicable.
If you are interested in
integrating convolution into your application or music server, please contact us.
Custom DSP Software Development
Our DSP software development services use C++ for developing the fastest digital audio executables and cross
platform integration compatibility. While we specialize in using the Juce audio framework, we can
work with any C++ audio framework or library.
We can develop for Windows, Mac, Linux, iOS and Android
platforms. Whether it is a standalone application or plugin or integration with an existing code base, we
have you covered.
Full software development lifecycle capabilities from requirements analysis,
design and implementation services and real-time audio testing services.
We use GitHub and are
fully trained and experienced in software DevOps best practices including continuous integration and
