AI Digital Audio DSP

Specification: 12x8
The AI intelligent speech processor adopts the AI noise reduction function of artificial intelligence width learning algorithm to reduce non-human noise during speech amplification, improve speech clarity, and achieve intelligent removal of non-human voice signals.
This product can be used in speech reinforcement venues such as conferences, education, and multifunctional halls.

Features

Vocal separation x AI noise reduction x width learning x big data analysis x extremely low latency


• AI noise reduction: AI noise reduction function based on width learning can intelligently eliminate environmental noise such as flipping books, writing, knocking on tables, and fans, achieving non human voice signal separation.
• Width learning (100000 hours): The network structure is constantly changing with learning, and the number of network nodes can be dynamically adjusted, making it easy to achieve online learning with extremely low latency.
• Processor: ADI SHARC 21489@450 MHz SIMD.
• DSP processing capacity: 400 MIPS, 1.6 GFLOPS.
• The input sensitivity can be adjusted to 17 levels, with a maximum of 48dB.
• Phantom power supply:+48V/Max 10mA.
• Provide 8 devices for simultaneous online operation.
• Automatic gain control (AGC), automatic control signal waveform and tone within an appropriate range, automatic gain control: -6dB to+18dB, automatic equalization control: -12dB to+12dB.
• Gain sharing automatic mixing (AM).
• 8-stage British parameter equalization, providing 5 filter options: Parametric, Lowshelf, Highshelf, Lowpass, Highpass.
• Provide customized operation interfaces for end users, supporting up to 30 devices to be managed on the same interface.
• Built in USB sound card, supporting music playback, recording, and soft video conferencing (such as Zoom, Tencent Meeting, DingTalk Meeting, etc.).
• Equipped with central control function, it can control the overall power supply, signal switching, environmental control, audio, and other functions in the system, achieving the functions required for one click opening of the system.
