Once you stop an oscillator, you cannot start it again. You didn’t do anything wrong, it’s the feature of the Web Audio API that optimizes the performance. What we can do is to create a sound class that will be responsible from creating oscillator nodes, and play and stop sounds. T...
灵活的处理音频流中的声道,允许对其进行分离与合并 可以从audio或video媒体元素中处理音频源 可以处理从getUserMedia函数获取的媒体流 与WebRTC集成:使用MediaStreamAudioSourceNode和webrtc处理从远端接收的音频;通过MediaStreamAudioDestinationNode和webrtc发送生成或处理过的音频流到远端 音频流的合成与处理可以直接使用JavaScr...
An introduction to the Web Audio API. In this lesson, we cover creating an audio context and an oscillator node that actually plays a sound in the browser, and different ways to alter that sound. varcontext =newwindow.AudioContext() ||newwindow.webkitAudioContext(), osc=context.createOscillator...

There's also aBasic Concepts Behind Web Audio APIarticle, to help you understand the way digital audio works, specifically in the realm of the API. This also includes a good introduction to some of the concepts the API is built upon. ...
The introduction of the Web Audio API1 in 2011 marked a significant advance for web-based music systems by en- abling real-time sound synthesis on web browsers simply by writing JavaScript code. While this powerful functionality has arrived there is a yet unaddressed need for an exten- sion ...
AudioNodes are cheap to create, thus the design of the Web Audio API encourages developers to recreate audio nodes as and when they’re needed. In our case, we would have to call the playSound function again. Conclusion I hope you have enjoyed this introduction to sound synthesis with the...
整体结构图如下所示,在web端需要使用HTML5的Web Audio API接收麦克风输入的音频流,进行适量的处理后实时传递给服务端;web与服务端之间的音频流交互通过SignalR来实现;具体的语音识别通过调用微软语音服务实现。 该web实时语音识别demo可以实现下面的功能: 可以通过网页传入麦克风音频 ...
