UMA-8 v2 USB 陣列式麥克風模組

miniDSP UMA-8 V2 MEMS Mic Array 是一款 Array Mic 陣列式麥克風,為 Multi-Channel USB 麥克風陣列,基於 XMOS Vocal Fusion 系列(XVF3000)晶片打造。

  • 改良自適應波束成形:提供精確的聲音追蹤。
  • 全雙工聲學回音消除(AEC)及強制輸入功能(Barge-in):即使在嘈雜環境中也能實現高效的聲音辨識。
  • 噪聲抑制與自動增益控制(AGC):優化語音質量。

該裝置採用七個高性能 MEMS 麥克風,配置成圓形排列,適用於各種應用的高品質語音捕捉。UMA-8 整合 DSP 處理器,支援多種語音處理演算法,包括波束成形、噪聲抑制、回音消除以及去混響功能。作為完全符合 UAC2 標準的音訊接口,UMA-8 在 Mac/Linux 系統下無需驅動程式支援,Windows 系統則支援 ASIO 驅動程式。

產品特色

  • 多通道 USB 麥克風陣列:專為語音命令設計。
  • 內建 DSP:支援波束成形、噪聲抑制、回音消除、去混響、方向來臨判斷(DOA)及語音活動檢測(VAD)。
  • 11 顆 RGB LED 環形配置:提供狀態指示。
  • 高品質 MEMS 麥克風:使用 Knowles SPH1668LM4H。
  • 彈性韌體選項:DSP 模式支援 2ch 波束成形、RAW 模式支援 8ch MEMS 音訊。
  • 擴充接口:支援額外的 PDM 麥克風連接、I2S 輸入/輸出擴充和 GPIO。
  • 完整的應用指南:支援 Google SDK、Alexa-Pi、Cortana、Siri、IBM Watson 和 Matlab,並持續更新中。

應用範圍

從 DIY 愛好者到 OEM 製造商,UMA-8 平台經過精心設計,可靈活適應不同的韌體、軟體和硬體需求,隨著您的應用不斷成長。
