问题描述
我目前正在使用javascript中的Web Audio API开发音频Web应用程序，但我发现了一个问题：我需要同时从不同的设备录制到不同的轨道（想象一下，如果声卡有8个输入录制在8个缓冲区中独立地录制鼓手），但我还没有找到任何方法告诉AudioContext您必须录制哪个设备：（
I'm currenly developing an audio web application using Web Audio API in javascript, but I found a problem: I need to record simultaneously from different devices to different tracks (imagine for example a sound card with 8 inputs recording in 8 buffers independently in orderto record a drummer), but I have not found any way to tell the AudioContext from which device you must record :(
任何人都可以帮助我吗？非常感谢：）
Can anybody help me? Thanks a lot :)
推荐答案
那么你可以拥有多个麦克风 - 但前提是它们已插入多通道接口。通过使用约束多次调用getUserMedia来选择不同的输入来解决单独的设备 - 查看。不过，我不确定我们是否已接通支持。
Well you can have multiple microphones - but only if they're plugged into a multi-channel interface. Separate devices would be addressed by calling getUserMedia multiple times with a constraint to select different inputs - look at https://simpl.info/getusermedia/sources/index.html. I'm not sure if we're wired up to support that yet, though.
