Description

方案一:多通道麦克风阵列委托定制
因实时语音分离需要,现定制设计一款同步语音采集设备,具体技术指标如下:
1) 同步采集多个通道,通道间采样无延迟;
2) 通道数量至少8 个;
3) 最高采样频率48000Hz,支持8000Hz、16000Hz、44100Hz 和48000Hz 可选档位;
4) 采样精度(位深度)16 位以上;
5) 具有可调增益最大40dB;
6) 采用麦克风与采样设备分离设计,每个麦克风体积不超过长2CM×宽1.5CM×高1.5CM;
7) 麦克风与采集设备之间采用柔性线缆和微型连接器可靠连接,线缆长度不小于50CM;
8) 采集设备兼容USB2.0 接口,符合标准声卡传输协议,支持Linux 平台通用标准声卡驱
动程序;
9) 所有设备仅通过USB 接口供电;
10) 交付时提供硬件设计资料与软件源代码。
定制周期:自合同签订日起3 个月内完成并通过验收。
方案二:八通道USB 声卡开源硬件委托加工
现有一款支持ROS 平台的声卡开源设计资料,委托贵方加工制造并进行测试。REV3 的
全部设计资料可在网址:https://sourceforge.net/p/eightsoundsusb/wiki/Main_Page/进行下
载查看。主要技术指标如下:
1) 应用USB Type B 接口连接;
2) 通过电脑USB 接口供电;
3) 兼容USB 2.0 接口,最高速度480Mb/s;
4) 支持Windows 和Linux 标准声卡驱动;
5) 支持8 个模拟通道差分输入(RJ11 输入接口);
6) 2 个模拟立体声输出通道(3.5 mm jack 输出接口);
7) 同步8 通道差分输入,所有通道之间无采样延迟;
8) 支持标准采样频率 - 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, 192 kHz;
9) 支持位流数据输出;
10) XSYS2 编程接口,保留XMOS XTAG2 调试接口;
11) XMOS 扩展接口,通过 I/O 可扩展L-type Core XMOS;
12) 噪声信号采集要求-0.1% THD;
13) 测试点 – 保留ADC/DAC, 供电等原设计中所有测试点。
加工周期:自合同签订日起2 个月内完成并通过验收。
