![]() These methods copy data into a specified array, so you need to create a new array to receive the data before invoking one. To capture data, you need to use the methods AnalyserNode.getFloatFrequencyData() and AnalyserNode.getByteFrequencyData() to capture frequency data, and AnalyserNode.getByteTimeDomainData() and AnalyserNode.getFloatTimeDomainData() to capture waveform data. Read those pages to get more information on how to use them.
