getPitch(float[] audioBuffer) Analyzes a buffer with audio information and estimates a pitch in Hz.

Method Detail

getPitch

PitchDetectionResult getPitch(float[] audioBuffer)

Analyzes a buffer with audio information and estimates a pitch in Hz. Currently this interface only allows one pitch per buffer.

Parameters:

audioBuffer - The buffer with audio information. The information in the buffer is not modified so it can be (re)used for e.g. FFT analysis.

Returns:

An estimation of the pitch in Hz or -1 if no pitch is detected or present in the buffer.
