Intending to improve the smallest audio component found in smartphones, wearables and Internet of Things (IoT) devices, a new Boston based sensor company called Vesper has designed a microphone that it says will enhance consumers' acoustic experience with voice capture and sound recording. Though such microphones are virtually invisible to consumers, the market for the highest-performance devices is huge: the research firm IHS predicts that it will reach $718 million by 2017. Vesper says that its microphone technology offers the highest signal-to-noise ratio (SNR) in ultra-compact form factors for consumer microphones: 70 db SNR, which is one of the key determining factors in acoustic performance. Vesper has reportedly raised $5 million from federal grants, Atlas Ventures, and an undisclosed customer. The company's CEO Matt Crowley previously co-founded Sand 9, a MEMS based oscillator company.
