Member Function Documentation

static double detectPitch ( const File &  fileToScan, AudioSampleBuffer &  workingBuffer, double  sampleRate  )

inlinestatic

Scans a whole file and returns the pitch.

You have to supply a working buffer that is used to read the data from the file. It must be stereo and have the desired length that can be obtained by getNumSamplesNeeded()

static double detectPitch ( const AudioSampleBuffer &  buffer, int  startSample, int  numSamples, double  sampleRate  )

inlinestatic

detects the pitch in the audio buffer.

static int getNumSamplesNeeded ( double  sampleRate )

inlinestatic

Returns the number of samples that is needed to detect 50 Hz.

static int getNumSamplesNeeded ( double  sampleRate, double  minFrequencyToAnalyse  )

inlinestatic

Returns the number of samples that is needed to detect the given frequency.
