- Omnidirectional Noise Cancellation: Removes background noise from both sides of a call in real time, so the other person does not need Sanas installed.
- Voice Isolation: Keeps the primary speaker while removing background noise and distant voices, which helps agents stay understandable in busy spaces.
- Standard mode: Removes environmental noise while keeping other human speech audible, which is useful at shared workstations and in multi-speaker settings.
- Background speech cancellation: Filters unwanted voices as well as environmental sounds, helping the main speaker remain clear when other people are talking nearby.
- Noise suppression: Handles background noise up to 80–90 dBA and supports more than 8,000 noise profiles, covering a wide range of noisy calling environments.
- Automatic Volume Optimization: Adjusts outgoing volume in real time so speech does not become too quiet or excessively loud during a call.
- On-device processing: Processes call audio on the user’s device instead of sending it elsewhere, which helps organizations keep audio within their environment.
- Low-latency processing: Noise Cancellation runs at about 40 milliseconds of latency, helping conversations continue without a noticeable processing delay.
Sanas Noise Cancellation
Real-time call audio repair and noise removal for contact centers
Updated August 28, 2026
Sanas Noise Cancellation Overview
Sanas Noise Cancellation is real-time audio software that removes background sounds from live conversations. Contact center agents use it to keep their speech clear when calls happen around office noise, keyboard sounds, fans, pets, or other people.
It is mainly for contact centers and customer-facing teams that handle many voice calls. It can run with existing calling setups and is useful at shared desks, open offices, home workspaces, and other noisy locations.

Pros
| Competitor | Pros |
|---|---|
| Krisp | Sanas Noise Cancellation has separate AI models for inbound and outbound audio, including an inbound model made for far-field sources such as speakerphones and car audio. Compared with Krisp, that gives contact centers processing built around the different conditions on each side of a call. |
| IRIS Clarity | For very loud contact center floors, Sanas says its outbound model cancels noise up to 80–90 dBA and covers more than 8,000 noise profiles. IRIS Clarity removes noise from incoming and outgoing audio but does not publish those same coverage figures on its current product pages. |
| CrystalSound | Contact center admins can enable Sanas Noise Cancellation for a whole group and stop users from switching it off. CrystalSound has team license management, but its current site focuses more broadly on online meetings, recording, and individual audio controls. |
| Utterly | Sanas Noise Cancellation targets contact center conditions such as nearby agents, speakerphones, traffic, and background TVs. Utterly’s paid Elevate plan lists coverage for 500+ dynamic and static noise types, making Sanas the more specialized option for dense calling environments. |
Cons
| Competitor | Cons |
|---|---|
| Krisp | Krisp combines bidirectional noise cancellation with echo cancellation and lets admins adjust customer-side cancellation across five levels. That gives teams more control when they want some ambient sound, hold music, or dial tones to remain audible. |
| IRIS Clarity | A speaker-side slider in IRIS Clarity lets users change how much incoming noise is removed. Sanas lets users switch inbound cancellation on or off, but its current guide does not show an equivalent adjustable suppression slider. |
| CrystalSound | CrystalSound includes bidirectional cancellation, acoustic echo suppression, adjustable noise reduction, microphone boosting, and 48 kHz stereo voice. Teams wanting those audio controls in one app have more options beyond noise removal. |
| Utterly | Utterly has a $0 plan with unlimited microphone and speaker noise cancellation, while Elevate costs $5 per month and covers 500+ noise types. Its public pricing makes it easier for a small team or individual to know the cost before installing it. |
Reviews
- AWS Marketplace (Rating 5/5 from 1 rating). The reviewer says Sanas is easy to manage, improves agent performance, and eliminates background noise. They report that some headsets are incompatible, though they say the issue can be resolved.
- Reddit. One commenter says their workplace has Sanas built in and that its noise cancellation is very effective even when someone nearby is shouting. They do not mention any problems with it.
