# AI models: Noise Cancellation

### Introduction

The following document lists Sanas' Noise Cancellation (NC) model releases. Versions are listed newest-first. Each entry summarizes what changed and who it affects.

Sanas NC uses independently trained AI models for each audio direction — outbound (agent-side) and inbound (customer-side) — because each faces distinct acoustic challenges. Outbound models handle near-field speech in noisy environments, while inbound models handle far-field speech from unpredictable sources like speakerphones or car audio.

For desktop application releases that bundle these models, see [Product updates](/portalv3/docs/product-updates). For detailed benchmarking methodology and performance data, see [Sanas science blogs](https://www.sanas.ai/science).

#### NC2.6.1

| **Field** | **Detail** |
| --- | --- |
| Model version | 2.6.1 |
| Speech capability | Noise Cancellation |
| Audio direction | Inbound (Call recipient’s side) |
| Release status | GA |

**Whats changed**

- First inbound NC model, enabling Omnidirectional Noise Cancellation across all call participants.
- Purpose-built for far-field and variable-quality audio sources (speakerphones, car audio, mobile mics), where distant speech is the signal to preserve rather than suppress.
- Handles unpredictable ambient environments (background TVs, traffic, other people) through an AI model trained specifically for inbound scenarios.

#### NC1.2.1

| **Field** | **Detail** |
| --- | --- |
| Model version | 1.2.1 |
| Speech capability | Noise Cancellation |
| Audio direction | Outbound (Sanas App user’s side) |
| Release status | GA |

**What changed**

- Cancels background noise up to 80–90 dBA, significant improvement over the 60–70 dBA range typical of other solutions. Built for high-density contact center floors where adjacent agents are often audible on calls.
- Goes beyond environmental noise to cancel background speech using spatial and acoustic cues such as distance-to-mic, preserving only the foreground (main) speaker.
- Supports over 8,000 noise profiles covering both contact center and work-from-home environments, with no hardware installation required.
