Near Field offerings

Standard Acoustic Suite

Ittiam ACS standard offering includes state-of-the-art Acoustic Echo Canceller (AEC), Ambient Noise Reduction (ANR) and Automatic Gain Control (AGC) to enhance uplink and downlink speech quality. Audio playout level is controlled for speaker protection and compensates automatically for the changing background noise. Overall, ACS solution is aptly suited for the mobile environment and well tuned for different mobile use cases.

Beyond mobile phones, the solution targets desktop IP phones, tablets and laptops. It also supports Boombox application where an external loudspeaker can be connected to the mobile device for ease of communication and/or to enable multiple users to join the call.

Boombox

Boombox- Enabling group conferencing on Mobile phones

Using two microphones on mobile phones, Ittiam ACS achieves superior noise cancellation in the most noisy environments (like traffic and horn noise) and provides a clear and natural voice.

dual microphone

Audio focus includes state-of-the-art audio beam forming technology which focuses on the target user and reduces all other background noise and interference. The standard solution supports two microphones. For devices with 3 or 4 microphones, custom solution can further enhance voice quality.

Audio focus enables high quality voice conversation experience, typical use case include Interview recording and Voice recognition applications.

Voice-Recognition

Voice Recognition on Mobile Phones

Audio focus, uses state-of-the-art audio beam forming technology, achieves ‘noise free’ video recording with high quality voice commentary and focus on particular audio source (active speaker) in video recording.

For video recording and news gathering (interviews) applications, it enables high quality voice recording. With focus on the target person, background noise is reduced significantly.

Far Field offerings

Standard Acoustics Suite

The standard acoustics suite includes all standard features to enable high quality far-field communication applications. Video conferencing and Telepresence are key applications in the business domain. In homes, video calls using smart-TV or one with set-top boxes is a good use case. Smart devices that can use voice commands to control light, sound, temperature or any similar things for overall home-automation, are also covered.

Audio focus for video conferencing application includes state-of-the-art acoustic features like AEC, ANR, AGC and multi-microphone based audio beam forming solutions.

Audio focus can form simultaneous multiple beam, and can track an active speaker. Multi-microphone Beamforming can support large distance beam formation upto 5 meters and detect active user.

Audio focus can also achieve high quality voice communication in large living room/business video conferencing system.
