True Pioneers in Active Noise Reduction
recalm: Specialists for Active Noise Reduction
What originally began as a vision to reduce noise at the push of a button without headphones has evolved into the development of groundbreaking products and technologies. Specializing in Active Noise Cancelling (ANC), they aim not only to reduce everyday noise but also focus on specific applications such as the driver cabins of construction and agricultural machinery. In doing so, they have successfully integrated their first fully functional ANC device into this specialized environment.
But the company’s ambitions go even further: In addition to ANC, recalm is developing additional audio features designed to further enhance users’ lives. These include dynamic hands-free functionality and entertainment options via Bluetooth and DAB+. Their product portfolio is a constantly growing ecosystem of solutions that also address the emerging need for Road Noise Cancelling (RNC) in the automotive market.
The Starting Point: An Ambitious Goal
recalm has the challenging mission to develop and perfect active noise cancellation for open spaces. Their pursuit of technological excellence, however, demanded highly specialized expertise, particularly in the areas of digital signal processing and embedded systems.
What recalm Needed:
- Expertise in Signal Processing: To efficiently utilize their hardware.
- Specialized Freelancers: With the necessary skillset to tackle the technical challenges.
- Maximum Flexibility and Sustainable Growth: To handle peak workloads efficiently.
At that time, recalm had already developed initial prototypes and received both private and public funding. However, they faced a significant challenge:
Creating an ALSA (Advanced Linux Sound Architecture) class to serve as a standard interface for two sound cards:
BluezALSA: This involved integrating a stereo input and a SCO (Synchronous Connection-Oriented) interface into a Bluetooth mobile interface. Reading and writing audio data had already been tested, and the task was to finalize the software interface.
HWALSA: Here, the goal was to connect internal microphones and amplifier outputs through a custom ALSA sound card.
Since these interfaces operated on different clock systems, expertise in signal processing was required to synchronize the various signal streams via buffers to real-time clock.
Within a tight timeframe, we found highly qualified embedded system engineers for recalm who precisely met the company’s requirements.
