What is "Studio Recorder"?

"Studio Recorder", developed by the american printing house (APH), is an App to record and manipulate audio. More about this program including the download can be found here The users manual can be viewed here.

what does this addOn offer?

This addOn adds braille support as well as some additional keystrokes to ease the use of "Studio Recorder".

braille support

If you have a braille display, the content of the status bar is displayed on the braille display while you are in the main window of "Studio Recorder". This makes it possible to see the current time while audio is played back and/or while you record new audio. So you can always keep track of your position within the audio material.

The addOn displays all elements you have configured to be displayed in the status bar. In Studio Recorder's settings (CTRL+t) go to the TAB "Status Bar". Here you can tell "Studio Recorder" which elements you want to see on the status bar.

We recommend to check the following Items:

• background progress
• Message/status
• current time
• total time
• selection length

and to uncheck all other items.

additional keyboard shortcuts

The following shortcuts are added through the addOn.

• CTRL+Delete:
  delete all audio to the beginning
• ALT+Delete:
  Delete all audio to the end
• j:
  set start of selection.
  The normal key to do this in "Studio Recorder" is the left bracket, but this key can't be used on non-english keyboards.
• k:
  set end of selection.
• shift+j:
  select to beginning.
• shift+k:
  select to end.
• ctrl+j:
  go to start of selection.
• ctrl+k:
  go to end of selection.
• i:
  fade in.
  Marks all audio to the beginning and performs a fade in.
• o:
  fade out.
  Marks all audio to the end and performs a fade out.
• n:
  normalize all audio
  Marks all audio and performs a normalize.
• t: opens the dialog to trim silence from booth ends of the file

All keystrokes can be changed in NVDA's gestures dialog.
If you want to have Studio Recorder's original behaviour back for a keystroke, just delete it from the gestures dialog under "Studio Recorder".

The arrow keys do not speak if pressed, to avoid unwanted speech output while navigating the document.

alternate keyboard layer

If you e.g. use often marks, you might want to use the keystroke "n" to name a mark, which is the original behaviour, instead of doing a normalize. In this cases, you can press
NVDA+Space
to activate the alternative layer. If you press "n" now, it will name the current mark. After one key press, this layer is deactivated automatically. If you want it to stay active, just press
NVDA+space
twice times and it will stay active, until you press
NVDA+space
again. An asscending tone is played if this mode is active, a descending tone otherwise.

In summary: if you need a keystroke, wheere the addOn performs a different function than Studio Recorder, just press NVDA+Space followed by the corresponding key. This is an easy way to perform the original task without changing settings permanently.
