Sound Playback

  Press Playback to start playback.
  10 seconds of data of the spectrogram image displayed on the screen will be played back. If 20 seconds of data is recorded, you can change the part of the spectrogram to be played back by holding down the spectrogram section and sliding it (panning).
  Playback ends after 10 seconds, but if you want to end the playback halfway through, press  Stop  button.
  If the filtering process is being performed on the time waveform below, the filtered sound will be played.
  The video below shows an example of the filtering effect. The original sound is played first, followed by the filtered playback sound, in which the frequency range other than the birdsong sound is attenuated.
