variable speed control for audio playback in the browser?

Question

Is there a way to change the playback speed of audio in the browser? What is best to accomplish this task, html5 audio, or flash, or something else? Are there any specific libraries that would help with this?

Accepted Answer

Use the Web Audio API.

In the following code I answered your other question.

best way to loop audio in the browser?

Modify the code in my answer above as follows for a playback speed example.

Right below

```
source.loop = loopOnOff;
```

add

```
source.playbackRate.value = 1; // change number to between 0.10 to 10 (or larger/smaller) to test.
```

You can also run the html audio tag through the web audio api and add effects processing.
