WebRTC samples WebAssembly Audio stream volume

+ +

Measure the volume of a local media stream using WebAudio and WebAssembly.

+ +
+
+
Instant:
+ +
+
+
+
Slow:
+ +
+
+
+
Wasm:
+ +
+
+
+ +

The 'instant' volume changes approximately every 50ms; the 'slow' volume approximates the average volume over about a second. This value is computed in Javascript.

+

The 'wasm' meter computes its value using WebAssembly.

+

Note that you will not hear your own voice; use the local audio rendering demo for that.

+

The audioContext, stream and soundMeter variables are in global scope, so you can inspect them from the console.
