Aiso™ software controls the sound you hear. Focus on the sound you need as well as the image you want.

Panning, zooming, applying a background blur… all common and familiar ways to edit video images. Now with aiso™ for Voice Communications users can have a similar level of control over the audio they share on calls or video recordings. Aiso™ works on a wide variety of multi microphone devices to capture the voices that matter, while suppressing background noise

Disrupted Voice & Video Calls

We want to be able to make calls or shoot videos anywhere, even when we’re amongst other people talking. Calls made in busy environments are easily disrupted by unexpected sounds – particularly nearby voices.
Existing solutions based on noise suppression may reduce listener fatigue but won’t improve speech intelligibility and won’t remove competing speech.
Technology that relies on beamforming only focusses a device’s microphones in a specific direction, amplifying all sounds in that direction.

Frustration Free Calls and Videos

To be effective, voice communication systems need to be able to distinguish the speech of interest from other speech sources while suppressing background noise. Because aiso™ for Voice Communication uses Blind Source Separation combined with Noise Suppression, it’s much more effective than beamforming solutions in isolating and extracting the desired sound source. Which means that users can focus on a particular person’s voice as easily as they can zoom the camera.

AudioCrop™ feature for video recordings

AudioCrop™ allows an area of a video recording’s frame to be selected. Sound sources originating from outside that area are then automatically discarded.

AudioTag feature for video recording

Ideal for video content creators, the AudioTag feature allows specific sound sources to be selected based on their location, with all other sound sources discarded. This means a voice interrupting a smartphone video can be removed, during, or after recording.

How it works
Asynchronous Acoustic Echo Cancellation

Asynchronous Acoustic Echo Cancellation

Voice communication devices need Acoustic Echo Cancellation (AEC) technology to prevent echo during calls. Most AEC solutions not only require access to both the microphone signal and the reference signal sent to the speakers, they also demand that these two signals be fully synchronized. Aiso™ AEC works with asynchronous microphones and reference signals, making it the ideal choice for video conferencing products that have their microphones and speakers integrated into different physical devices.

Key Benefits

Clear, Intelligible Speech

Improves speech intelligibility during calls, as well as reducing listener fatigue.

No Artefacts or Distortion

Preserves the original acoustic characteristics of the target speech signal and does not introduce artefacts or distortion to the audio.

Groundbreaking Source Separation

Improving Speech-to-Noise Ratio by 30 dB

Hardware Agnostic

Does not require a dedicated hardware codec or DSP with no need for special microphones.
