Acoustics

The phenomenal pace at which mobile devices have developed and the huge increase in their computing power has led to a surge in powerful media-centric smartphones. Despite this, the quality of audio while on call is still the main concern of the phone user. And, there is tremendous scope for improvement in this region. Superior acoustics is one of the cornerstones for providing rich communication experience.

Acoustics throws up a unique set of challenges in fixed and mobile devices for Voice and Video communication. These challenges include echo, background noise, audio level variation, etc. And this is why you have voice quality degradation in fixed and mobile devices. A large number of mobile calls do happen when you’re on the move, where traffic and general ambient noise is high. For a comfortable call, noise must be reduced and the audio volume should also be dynamically adjusted. A related challenge is acoustic echo which should be reduced sufficiently for full-duplex communication to happen. These acoustic issues can be handled by efficient signal processing on the device.

Ittiam’s Acoustic Clarity Solutions (ACS) suite provides a comprehensive portfolio of products for a variety of product needs. By dynamically adjusting to background noise levels, Ittiam’s Acoustic solution eliminates unwanted sounds, leaving clear, natural, echo-free, full-duplex voice communication while quickly adapting to changing acoustic conditions. With several patented technologies, Ittiam’s acoustic suite offers solutions for both handheld (near field) as well as fixed (far field) products for superior acoustics experience in voice/video communications. Ittiam’s ACS is also tightly integrated into its Video Communication Systems Media SDK for superior voice calling capabilities.

Beyond voice and video calling, the emergence of multiple microphones in devices also enables newer applications like audio focus where technologies like audio beam forming enable superior isolation of the targeted voice signal in applications like video recording, speech recognition, etc. A software based acoustic clarity solution which encompasses all these use cases can be a valuable addition to any smart device.

Ittiam’s cutting edge ACS solutions include Audio Focus – which utilizes multiple microphones on handheld devices to narrow down the subject’s voice, thus eliminating distracting ambient noise. Ittiam’s Dual Mic Noise Cancellation (DNMC) as well as Audio Beam Forming solutions enhance voice communications in a variety of product and microphone configurations.
