About recalm
recalm is a true pioneer in active noise reduction. What began as a vision to eliminate noise without headphones has evolved into groundbreaking products and technologies. Specializing in Active Noise Cancelling (ANC), they target not only everyday noise but specific applications, from driver cabins of construction machinery to the emerging Road Noise Cancelling (RNC) automotive market.
Their flagship product, ANCOR, represents a new generation of spatial noise reduction technology. Beyond ANC, recalm develops hands-free functionality and entertainment features via Bluetooth and DAB+.
The Challenge
Synchronizing audio interfaces on different clock systems: expertise that is extremely rare
recalm had developed initial prototypes and secured both private and public funding. The critical task: creating an ALSA class as a standard interface for two sound cards: BluezALSA (Bluetooth mobile interface integrating stereo input and SCO) and HWALSA (custom card connecting internal microphones and amplifier outputs). Since these operated on different clock systems, signal processing expertise was required to synchronize audio streams via buffers to real-time clock. This level of specialization is extremely difficult to source quickly on the open market.
What recalm Needed
Signal Processing Expertise
To efficiently utilize their hardware and synchronize audio streams across different clock domains in real time.
Specialized Freelancers
With the exact skillset in embedded systems and digital signal processing to tackle the specific technical challenges.
Maximum Flexibility
The ability to scale specialized support efficiently to handle project peaks without long-term overhead.
The Solution
The right embedded system engineers found within a tight timeframe
ElevateX was exactly the partner recalm needed. Beyond our specialized freelancer network, we brought expertise in quickly and precisely matching professionals to demanding technical requirements. Within a tight timeframe, we found highly qualified embedded system engineers who matched recalm's needs exactly, enabling a quantum leap in noise reduction technology.
Key Results
Three measurable outcomes from the partnership
Performance
Comprehensive optimization of core algorithms resulting in a significant acceleration of time-to-market metrics.
Cost
Strategic deployment of highly specialized freelancers, contributing to substantial cost efficiencies and operational leverage.
Quality
Amplification of product quality standards, leading to a measurable uptick in overall customer satisfaction and retention.
As a young company, we were in a transitional phase. We had to rapidly expand the product with a wide range of functions to meet increasing customer demands. It was only through the competent support of ElevateX that we were able to quickly find experts who executed a targeted implementation.
Conclusion
ElevateX and recalm have proven that the key to technological advancement lies in the right partnership and specialized expertise. In a complex and constantly evolving industry like audio technology, having the right people at the right time is not a nice-to-have. It is what makes the difference between shipping and stalling.
