We focus on audio analysis of breathing patterns, personalized breathing exercises and coaching to improve breathing for health, performance and care.

Our Technology

We identify characteristics and markers about your breathing based on microphone input.

We convert the airwaves from your breathing into sound waves, which allows us to apply new respiratory analytics that help decrease stress, increase feelings of well-being, enhance athletic performance, promote sound sleep and detect early signs of breathing difficulties. We can provide near instantaneous audio and visual feedback, which sets in motion wellness benefits that have never before been possible. And we can provide and track useful data about your breathing to help you improve your goals.

Every person has a unique breath sound based on anatomy, which can change in rate, intensity and frequency from breath to breath. We have developed state-of-the-art algorithms that can capture and accurately analyze breathing patterns, taking into account personalized unique breath signatures as they change over time.

Our respiratory measurements have been validated against more than 30,000 audio samples of breathing and our acoustic cardiopulmonary measurements were calibrated using the gold standard of clinical and research-grade equipment and software. 

We're fascinated by the 'shape' of breathing, a concept we have discovered that brings together characteristics about your breathing in an easy and intuitive way to visualize, listen to and understand.


Respiratory Acoustic Analyzer Library (RAAL)

The Respiratory Acoustic Analyzer Library (RAAL) consists of a wide set of sophisticated and robust digital signal processing algorithms designed and fine-tuned based on a large variety of breathing sounds and artifacts. Through a number of descriptors, metrics and statistic elements, we can extract a wide range of breath characteristics and nuances that can be used for breath optimization and early detection of possible respiratory anomalies and conditions.


CardioPulmonary Exercise Test Framework (CPET)

For more than four years, Breath Research has been developing a cardiopulmonary exercise test (CPET) based on pure audio input only. We are constantly refining our technology, with the goal of achieving the same high accuracy you’d get from doing the test using a clinical grade cardiopulmonary cart in a clinic or lab.
