Multi-view

Peter 30Dec19: ToDo-1 this page needs a lot of work - once the GUI is finalized and bugs removed.

Work in Progress...

Spectrogram and Wave displays of the same audio shown simultaneously in the same track.

Split Waveform and Spectrogram views

To get a split Multi-view for a track, select Multi-view from the track's Track Control Panel dropdown menu.

When a separation of views exists, the separation line can be dragged up or down to change the proportions of the split. You can drag until one of the sub-views shrinks to nothing.

Paul's Notes

• ESC key before mouse release cancels the drag, as expected.
• Either wave or spectrum view can be on top, depending on how you drag.
• Please note, and test, that the vertical ruler also divides in two portions, and that all mouse drag actions (including spectral selection) in the track view or the ruler are available, and only those proper for the sub-view.
• If you have a stereo track, then the wave and spectrum views keep the same

height proportions in the two channels.

• If you want to drag the channel separator instead, unfortunately there is no difference yet between the preview cursors. North-south seems the most sensible cursor for both of these drags, among pre-defined cursors.
• The drop-down menu of the track control panel may now have two checkmarks, for spectrum and for either Waveform or Waveform dB. Selecting any of those items causes that view type to become the sole view.
• In my opinion, the behavior above is not satisfactory. I think the more consistent user interface would have only Waveform and Spectrum items as a non-exclusive radio button choice in the menu, while the choice between linear and dB waveform view should be part of the right-mouse popup menu in the vertical ruler, analogous to the choice among scales for spectrum view.
• The 'VIEW property of *TRACK* in Nyquist is now a list rather than an atom when there is a split view. None of the existing .ny plug-ins that ship with Audacity need to be changed, because they only ever test whether the property is nil, indicating that an effect preview is being computed.
