Noise is a problem. Even in relatively quiet workspaces, the sounds of keys clacking, paper shuffling, and side-conversations are such constants that they seem to fade into a background hum. During video conferences, however, that background hum suddenly becomes a nagging, distracting irritant. For those who take their conference calls in less predictable environments, such as any public space, successfully handling an important call can be a struggle. Depending on the environment, it can become impossible. With remote conferences on the rise, noise pollution is a pressing issue for businesses and remote workers. 2Hz promises a Krisp* connection, every time.
Figure 1. Krisp* technology
Audio technology is nothing new, though it has jumped through a few technological leaps over the last few decades. Still, when 2Hz set out to create Krisp, they decided it was time to reinvent the wheel. Instead of relying on audio tech experts, they built a team of PhDs in mathematics and physics to tackle an old problem from the ground up.
“Using the GNA (Gaussian Network Accelerator) built into the 10th Generation Intel® Core™ Processors was integral to creating our Deep Neural Network which was trained to remove background noise and leave only clean voice.”
—Davit Baghdasaryan, CEO and Co-Founder 2Hz
The ubiquity of the problem called for a simple, downloadable solution that would be compatible with existing microphones and speakers, as well as all major conferencing software. To start, Krisp collected and processed tens of thousands of different noise and voice types. They used this cacophony to create a deep neural network capable of real-time noise cancellation beyond anything currently available. The Krisp app basically adds a virtual, intelligent sieve capable of isolating the sound of a caller’s voice and removing all unnecessary, extraneous noises in real time.
Krisp intelligent audio filter sits between your physical microphone or speaker and your conferencing app of choice. This allows you to control your own experience even if the offending noise is coming from the other end of the line. If you happen to be in a noisy area, you can turn on the Krisp Microphone control to filter out extraneous noise as you’re talking, without muting your own voice. The application will register and remove even sudden, unexpected noises like an ambulance driving by or a dog’s bark. If, on the other hand, you’re noticing a lot of distracting background noise coming through from the other caller, you can switch the Krisp Speaker control on and Krisp will filter out your caller’s environmental noise. There is no need for multiple mics or expensive speakers, although noise-cancelling headphones add an extra level of environmental control. Everything happens on your device, with almost no latency, and no data is ever sent to a server or even stored at all.
More companies are changing to reflect the way today’s digital workers want to “show up” for work. A remote workforce gives companies a larger pool of potential employees in more locations. The flexibility of remote work allows employees to better balance work and home lives. And less commuting is better for everyone, including the environment. Advancements in conference call technology are altering the way companies handle communication, making it easier and more affordable to coordinate meetings and connect to remote workers. Apps like Krisp are helping to make it possible to work on our own terms.
Currently available on existing CPUs for both Windows* and Mac*, Krisp promises to improve the experience even further by facilitating cleaner calls with intelligent noise control. Eventual enhancements include removing room echo, enriching voice quality, and the option to mute other voices. Paired with a quality pair of noise-cancelling headphones, a remote worker can create a virtual sound booth in a busy airport. This is all possible using a tuned piece of logic called GNA (Gaussian Neural Accelerator) that is built into the 10th Generation Intel® Core™ Processors.
Even before the official launch, the Krisp app had been downloaded over forty thousand times for use with six hundred apps, including gaming, podcast recording and, yes, conferencing. The technology is already being piloted by enterprise-scale and SMB contact centers to block background chatter and increase productivity. With a mobile app just around the bend, as well as a GNA optimized version, Krisp is poised to change our expectations for audio.
