{{APIRef("Web Audio API")}}

The **`frequencyBinCount`** read-only property of the {{domxref("AnalyserNode")}} interface is an unsigned integer half that of the {{domxref("AnalyserNode.fftSize")}}. This is the total number of data points available. Their indices have a linear relationship with the frequencies they represent, between 0 and the [Nyquist frequency](https://en.wikipedia.org/wiki/Nyquist_frequency).
The **`frequencyBinCount`** read-only property of the {{domxref("AnalyserNode")}} interface is the total number of data points available to {{domxref("AudioContext")}} `sampleRate`. This is half of the `value` of the {{domxref("AnalyserNode.fftSize")}}. The two methods' indices have a linear relationship with the frequencies they represent, between 0 and the [Nyquist frequency](https://en.wikipedia.org/wiki/Nyquist_frequency).
