Media Capture and Streams API (Media Streams)

The Media Capture and Streams API, often called the Media Stream API or the Stream API,  is an API related to WebRTC which supports streams of audio or video data, the methods for working with them, the constraints associated with the type of data, the success and error callbacks when using the data asynchronously, and the events that are fired during the process.

MediaRecorder API

The MediaRecorder API (MediaStream Recording) aims to provide a really simple mechanism by which developers can record media streams from the user's input devices and instantly use them in web apps, rather than having to perform manual encoding operations on raw PCM data, etc., which would be required when using Navigator.getUserMedia() alone.

SourceBuffer.appendWindowEnd

The appendWindowEnd property of the SourceBuffer interface controls the timestamp for the end of the append window, a timestamp range that can be used to filter what media data is appended to the SourceBuffer. Coded media frames with timestamps wthin this range will be appended, whereas those outside the range will be filtered out.

AnalyserNode.frequencyBinCount

The frequencyBinCount property of the AnalyserNode interface is an unsigned long value half that of the FFT size. This generally equates to the number of data values you will have to play with for the visualization.
