Highlights of Obi 4.6 release

Suppress unwanted noise using noise reduction

While recording the audio content of the book, some unwanted noise like sound from air-conditioner, laptop fan, etc., might get recorded. You can suppress these sounds by using the Noise reduction feature of Audio processing functionality. You can use this functionality from the menu item Tools->Audio Processing->Noise Reduction or from Multi phrase operations dialog.

Ability to apply noise reduction and normalization on multiple sections and the whole book

You can now apply noise reduction and normalize features of audio processing functionality on multiple sections and the entire audio of the book. The Multi Sections Operations dialog contains new buttons, Noise Reduction and Normalize, to give access to these features. You can also apply these operations on whole book. The dialog boxes for these operations have a checkbox Apply on whole book that enable this functionality.

Mix audio from external file to the content of the phrase

If you ever wanted to add a background music to some part of the book, you can do it with new Obi. Obi lets you mix audio from external files to the audio content of the phrase. The menu item Tools->Audio Processing->Audio Mixer gives access to this functionality.

Enhancements to fade in and fade out functionality

Earlier, Fade in and Fade out commands used to process audio from the beginning of the selected phrase. This release enables you to select a position inside the phrase from where the processing will be done.

Updated French language pack

Many thanks to BrailleNet, France for consistently updating the French language pack.

Import cue markers from wave audio file while importing audio

The import audio files functionality has been enhanced to import the cue markers along with the wav files. Cue markers are the time positions that can be embedded in the wav file when you are recording audio in tools like SoundForge , Adobe Audition etc. Obi detects the cue markers and splits imported audio at the cue markers from the wave audio file being imported. To enable this, select the radio button Split at cue points in wave audio files in the Import audio files dialog.

Export to DAISY can now also export To-do marks to CSV file

DAISY 3 and DAISY 2 export functionality now supports exporting To-do marks along with the exported audio file names to the CSV file. To activate this, check the checkbox Create CSV containing Todo timings in the Export dialog. The users can use the timing information in the CSV file to perform processing on specific parts of the respective audio files with the external processing tools.

Added support for new audio books specifications from W3C

W3C has been working on a new specification for audio books, which has been released recently. In order to aggressively support advancements in technology, Obi provides reference implementation of the W3C audio books specifications. You can select export to WP audio books from the Export dialog. Please note that this specification is very new, so its wide support should not be expected at this time.

Easily set default project directory while initializing Obi

The Obi’s initial Configuration Dialog now provides an option to set the default project directory for Obi projects. It provides the users an easy way to select a safe location for creating Obi projects, where they are less likely to face windows 10 permission related issues.

Option to start recording from the beginning of the section when the section has all empty pages

Some production houses create the structure of the book consisting of empty sections and empty pages before sending it to the narrators for recording. In this scenario, you would want to record at the beginning of the section instead of following the default behaviour of recording at the end of the section. You can enable this functionality by checking the checkbox Record at the starting of section with record section command if section has only empty pages. As the name suggests, if the section has all empty phrases, recording will start from the first empty phrase of the section.

Obi is now in GitHub

In September 2020 Obi development environment had been migrated to GitHub. The new repository is at https://github.com/daisy/obi/
