EasyListen™: Real-Time Speech Tempo Modification Real-time audio processing technology that slows incoming speech, making it more intelligible. Works by dynamically stretching (slowing) certain parts of speech—while adding no noticeable overall delay.

OnlyVoice™: In-Ear Microphone Processing Enables robust voice pickup in boom-less or short-boom headsets by exploiting benefits of SNR advantages of an in- ear microphone signal. Works by intelligently mixing internal (in-ear) microphone pickup with external mic array pickup to maximize voice intelligibility.

Dynamic Noise Suppression Reduces stationary and dynamic noises (e.g. approaching car) in single-channel speech signals without noticeable

• artefacts. Dynamic Noise Suppression increases the signal-

to-noise ratio and improves speech intelligibility thus reducing listening fatigue.

Wind Noise Reduction (WNR) Automatically detects and attenuates wind noise while preserving clear speech. WNR uses sub-band processing to filter out wind noise in affected frequency regions leaving “good” frequency regions untouched.

Acoustic Echo Cancellation (AEC) Eliminates acoustic coupling between speaker and microphone, allowing high-quality, full-duplex voice communication without echo. Alango AEC technology supports mono and stereo echo cancellation with very fast adaptation times. Alango AEC includes highly efficient, sub-band Acoustic Echo Suppressor

Alango Technologies – Company Presentation 2019

Acoustic Feedback Reduction Alleviates acoustic feedback by using sub-band adaptive filtering, noise and howling suppression, and quasi- proportional frequency shifting.

Back to Appendix

Adaptive Dual Microphone Creates a directional or noise-canceling microphone using just two omnidirectional microphones. Adaptively changes mic directionality to achieve best possible noise reduction. Includes adaptive wind noise suppression. Allows optional microphone calibration during the production.

Multi-Microphone Arrays Multi-microphone adaptive beamforming with 2 or more microphones. Allows multi-beam configurations and sound of arrival detection. Robust to wind noises.

Back to Appendix

Automatic Volume and eQualization Control Improves perceptual loudness and intelligibility of voice in dynamic environment with changing noises. Works by automatically amplifying and equalizing sounds in response to ambient noise characteristics.

Alango Technologies – Company Presentation 2019

21

Alango voice technologies

Back to Appendix

Automatic Gain Control Used in conjunction with Dynamic Range Processing to amplify a weak voice signal. To reduce noise pickup, gain is applied only when user voice activity is detected.

Alango Technologies – Company Presentation 2019

22

Back to Appendix

Multiband Dynamic Range Processing Adjusts the dynamic range of an audio signal by

• splitting into frequency sub-bands,
• processing each band according to specified characteristics, and
• synthesizing the resultant signal.

Alango Technologies – Company Presentation 2019

23

Back to Appendix

Voice Activity Detection Differentiates between voice and ambient noises in an acoustic signal, enabling low-power operation of always-on devices. The VAD block acts as a low-power “watchdog,” alerting the system to use heavier processing blocks only when the user’s voice is detected.

ListenThrough™: Environmental Audio Awareness Improves situational awareness for stereo headset users Important external sounds are emphasized to avoid masking by music, while ambient noise is filtered out.

MuRefiner™: Music Enhancement An integrated set of DSP technologies to enhance the audio experience in music and entertainment applications, including:

• stereo expansion (normalization)
• spectral enhancement,
• bass correction and amplification

Multiband Dynamic Range Processing Improves the listening experience by adjusting the dynamic range of an audio signal. Applies dynamic range processing to frequency sub-bands

• f the audio signal, recombines the sub-bands after

processing, and optimizes gain of the resultant signal.
