Zooming in/out the displayed area, changing the time axis format, etc.

### Zoom In

Zoom in the displayed area. The zooming in is centered at the cursor position.

### Zoom Out

Zoom out the displayed area. The zooming out is centered at the cursor position.

### Zoom Full Out

Zoom full out.

### Zoom Region

Zoom in the selected region.

### Time Format

Change time axis format. This setting will be valid for all windows.

- Second
- Milli Second
- Point
- Separated Second The format is ``Hour:Miniute:Second''.

### Zoom In Vertical Axis

Zoom in vertical axis.

### Zoom Out Vertical Axis

Zoom out vertical axis.

### Zoom Full Out Vertical Axis

Zoom full out vertical axis. This is the initial zooming state.

### Align Vertical Axis

Align the vertical axis of other windows with the current vertical axis.

### Display Information Area

Display information area to show label information.

### Draw Detail

Draw detail of waveform. This setting makes the drawing speed slower. Delailed drawing is sometimes invalied when the file is very long.

### Draw Labels

Draw labels. The waveform will be hidden by labels when many labels exist. In this case, turning off drawing labels is useful.

### Log Frequency Axis

Enable logarithmic frequency axis. This setting is valid for data with frequency axis and spectrogram data.

### Spectrogram

- No Spectrogram
  Draw normal waveform.
- Wide Band Spectrogram
  Draw wide band spectrogram.
- Narrow Band Spectrogram
  Draw narrow band spectrogram.
- Smoothed Spectrogram
  Draw narrow band smoothed spectrogram by cepstrum. The smoothed rate depends on Lifter Length in Analysis Dialog.
- CQT Spectrogram
  Draw CQT spectrogram. The CQT analysis has a feature that the frequency resolution is similar to the human auditory system whose frequency resolutions in the lower frequency region and in the higher frequency region are higher and lower, respectively. The CQT spectrogram is useful to visualize a music signal. The analysis condition is determined by the settings of CQT Parameters in Analysis Dialog. This function is introduced in version 0.9.
- Draw Piano Keyboard
  Draw a piano keyboard for spectrogram.
- Update Spectrogram
  Redraw spectrogram.
- Spectrogram Setting...
  Change the spectrogram setting by Spectrogram Dialog.
