+	  Select for phase_vocoder component. The component provides
+	  render speed control in range 0.5-2.0x. The pitch is
+	  preserved in audio waveform stretch or shorten. The module
+	  is using a frequency domain algorithm in STFT domain to
+	  interpolate magnitude and phase of output IFFT frames from
+	  input FFT frames.
