The solution utilizes Adaptive Feedback Cancellation to avoid annoyingly loud ringing feedback.

Using Beamforming to Focus on User

Using beamforming technology to establish a focused pickup range, the system suppresses sounds outside this range by up to 20 dB—significantly reducing amplifier noise levels. Users can flexibly adjust the pickup angle between 10° and 180°, with a precision of ±10°.

Low Latency Avoids Stuttering

Low Latency Avoids Stuttering

Neuroscience research and real-world experience demonstrate that poor-quality amplification systems with high latency or echo feedback impair speakers' cognitive fluency—making it difficult to organize thoughts, causing stuttering, and sometimes forcing them to stop speaking altogether*. An amplification system shouldn't act as a speechjammer that creates mental stress. For this reason, our solution maintains system latency under 18ms, enabling users to speak naturally and fluently.

*This phenomenon is caused by Delayed Auditory Feedback in people who do not stutter.

Be Heard Loud and Clear

Adaptive Feedback Cancellation (AFC) dynamically identifies and suppresses acoustic feedback, preventing howling or whistling and enabling higher amplifier gain up to 10 dB. Meanwhile, Automatic Gain Control (AGC) maintains consistent voice levels at varying distances between user and microphone.

High Resolution DSP

High Resolution DSP

Built‑in AFC, AGC, NS, and BF algorithms run in real time at 32 kHz @ 24-bit resolution, providing clear and reinforced voice.

Voice Optimization Algorithms

AFC
AFC

Adaptive Feedback Cancellation (AFC) reduces by the microphone array even with high-volume loudspeaker output.

Beamforming
Beamforming

Enhances voice by spatially filtering sound signals, focusing on desired sources while attenuating noise from unwanted directions.

Automatic Gain Control
Automatic Gain Control

Adjust audio signal levels to maintain optimal volume continuously. Ensuring that all speakers are heard clearly regardless of distances from the microphone.
