Highlights of Obi 4.0 alpha release

Obi is upgraded to .NET 4.0 and support for Windows XP is deprecated

New Obi uses .NET 4.0 (based on latest CLR 4.0) instead of .NET 2.0. This upgradation to CLR 4.0 is a major step forward to provide a base for up grading Obi to the latest versions of .net frameworks in the future releases, and to enable the use of latest libraries. The support for Windows XP is also deprecated from this release onwards, the users of Windows XP should install Obi 3.9.1.

Automated page generation

Obi enables you to insert page phrases in your recorded book by an automated process. Click Phrases->Auto Page Generation on the menu, and you will be presented with a dialog box to specify the parameters like time gap in pages, starting section, etc. Clicking OK on the dialog box will result in generation of page phrases in the entire project spaced at time interval entered by you in the dialog.

New German language pack added

Obi now also comes in German! Many thanks to Hermann Dremel (atz) for translations.

Option to import old NCC files with Windows 1252 encoding to prevent distortion of characters

Now you can choose to import NCC files with Windows 1252 encoding. This helps to preserve non-English characters while importing old NCC files that may otherwise get distorted. You can activate this option by checking the checkbox Import NCC files with Windows 1252 encoding in the Project tab of the Preferences dialog.

Option to play the phrase just recorded

You can now instruct Obi to play the phrase just recorded as soon as recording stops. To enable this feature, check the checkbox Play the recorded phrase when recording stops in the Audio tab of the Preferences dialog. If the audio was recorded in multiple phrases in the recording session, audio from the last recorded phrase will be played.

Choice of merging first two phrases after on-the-fly phrase detection

You can choose to merge first two phrases after the process of on-the-fly phrase detection. This will be useful when recording starts from the beginning of the section as it prevents silence phrase at the beginning, which becomes heading phrase by default. To activate this feature, check the checkbox Merge first two phrases after recording with phrase detection in the Audio tab of the Preferences dialog.

You can find help on the functionality of these features in the “What’s New?” page of Obi Help, which can be viewed by clicking on the Help contents menu item under Help menu of Obi.

List of some major bugs fixed & behaviour changes made in this release:

  • Sometimes the cursor in Zoomed Waveform View scrolled out of visible area on execution of audio editing command or during undo.
  • The state of Preserve Zoom check box is now saved on closing zoom waveform view.
