UMA-8 v2 USB 陣列式麥克風模組

UMA-8 v2 是一款 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。
