Signal From Noise
Redefining Mobile Voice Quality
At Cypher, we’ve silenced unwanted noise using a new, software-only approach. We eliminate over 99% of background noise while significantly boosting clarity. We also improve speech recognition performance. Our software is small, fast and ready to integrate into a wide range of applications.

 Hear the Signal,
Not the Noise

There are many situations where you can’t control when and where the call is made. That can mean lots of background noise. Existing technology can have a hard time with noises that are impulsive and periodic. They also have a hard time when it’s human-on-human babble. Cypher uses a different approach to mask out the hard-to-handle noise types. Listen for yourself.

A Better Approach
to Signal Processing

Traditional voice enhancement and noise-cancellation methods are limited. They require audio processing chips or multi-microphone arrays. Because they rely on custom hardware, they require costly, early-stage integration into product design and limit flexibility. Finally, the traditional methods are typically only really effective on constant noise sources from fixed locations.

Cypher software is composed of sophisticated pattern recognition and data manipulation algorithms that detect and separate acoustic signals. This dramatically suppresses background noise and significantly enhances voice quality and intelligibility. Our patented voice-printing technology identifies and isolates the speaker from all types and sources of noise.

Step 001


Cypher takes the audio and breaks it into segments to look for specific sound patterns found in human speech.

Things like frequency, harmonics and attack and decay characteristics can distinguish people from environmental noise.

Step 002


Then we compare the speech against a database of voice prints – either generic or custom depending on the application. Based on the match, different filters are used to cut out virtually everything else.

Step 003


Post processing is the final step. Here Cypher algorithms enhance the voice signal and remove artifacts created in the background noise elimination. This recreates a balanced, full sound as close to the original speaker as possible.

The Result

Standards-based testing shows up to 99% noise reduction and a 20% improvement in audio quality.

Noise Reduction

With no custom hardware required, compared to major phone manufacturers. For more information, contact us.
