This is an old revision of the document!
This page is the instructions for how to use Converter Plus (formally NAC). As this is an ongoing project, this page is subject to updates as we improve the application and workflow.
The purpose of Converter Plus is to perform a rapid DAISY conversion, requiring as little human intervention as possible. Moreover, all required interaction takes place in one simple phase, so operators need not return to the computer to complete a conversion. The interface is clean and simple, so is entirely accessible to screen readers. Independent of any particular device or platform, a conversion can be requested from virtually any web-capable device anywhere in the world. Finally, because the original audio files are not modified, the quality of the input tracks is not affected by a conversion.
If you are working on a patron request, and it is an audible file, you may need to edit it before you upload it into Converter Plus.
Now to dive into using Converter Plus!
First, you will need to navigate to the Converter in your web browser.
Your First Name
You are now in your profile for Converter plus. On this page, you can choose to either
Add a Book or open a current project in the dropdown menu labeled
Now that you have your book uploaded you can start making any necessary changes.
You should now be on the project page that displays the file name at the top of the page with the phrase
is now open
Below you will find a list of options under
What would you like to do?
If you are working on multiple titles you can use batch mode to upload titles or export titles in batches. This feature has been created to save time, especially if you are working on a remediation project.
On the welcome screen, for your profile page, there is a button located just below your name and the
Log Out link. This button is titled
Turn on Batch Mode. This button is designed to save you time with downloading and exporting a large number of titles.
When you turn it on there is a beep to tell you it is on. The button will now read
Turn off Batch Mode. This indicates it is on.
When you go to upload or export a book in batch mode, Converter Plus will tell you immediately that it is uploaded. This is a bit of a trick, as it is simply setting it up for batch mode.
When you go back to the welcome screen the button will now read
Execute # of jobs. Press this button when you are ready to upload or export your titles. You can now close your browser, and when you come back the next day everything should be completed!
Each title needs to go through a quality assurance check before it can be downloaded and published. This section is for any staff assigned to QA.
When we get Audible Files they are a single MP3 file. Converter Plus does not parse these down into correct sections and chapters, so you will have to edit the file with the directions below.
You will need to have a copy of Audacity on your computer to complete these edits.
Make sure the Audible MP3 file is downloaded onto your computer and open Audacity. To open the Audible MP3 in Audacity:
Now that the file is open in Audacity you need to first mix it down from Stereo to Mono. We do this because Mono files are smaller and easier to download, upload, or play on your device.
To mix the file down to mono:
Mix Stereo down to Mono
You will need to use zoom in and zoom out to help you see the breaks in the wave files to help you find pauses that indicate new sections and chapters.
You can use the
Zoom in and
Zoom Out icons on the Zoom toolbar at the top left of the Audacity screen.
If you have a Mac you can use the following shortkeys:
command + 1
command + 3
If you are on a PC you can do similar commands with the control key.
If you have a trackpad you can use the spread gesture on your trackpad. Make sure you have two fingers on the trackpad at the same time and spread them apart to zoom in and bring them back together to zoom out.
You can use the double finger swipe gesture to move back and forth through the track in the viewer.
When you hover your mouse over the time-track toolbar above the viewer you will see a green arrow. This is your quick player. When you click down on this it will start to play from the point it is over. You can move this by moving your mouse back and forth over the toolbar.
You can also use the
Stop buttons on the top-right menu above the viewer.
Once you can see the track in more detail, you will be able to see the gaps in the recording that will help you to see where there are pauses between sections and chapters.
To Edit the tracks:
File>Export>Export Selected Track
Once you select
Export Selected Track a popup window for
Save. You need to save this selected track as follows:
01 Title Page
New Foldernamed the title of the book to save all your files in.
Force export to mono
This will take you to the metadata section. Fill out the following:
Artist Name= Name of Author
Track Title= Name of Section (example, Title Page)
Album Title= Name of the Book
Track Number= Number in Sequence for Book Sections (example, if this is for a Title Page then the Track Number is 01)
Year= The year you are creating this version
Comment= Put the narrator here and enter it as
Narrator: Firstname Lastname
You will then be taken to a window for
Invalid Sample Rate. Change this to
44100 and hit the
Track Numbereach time.
Repeat this for each section of the book. Once you have each book section exported as its own track you can zip the file and upload it to Converter Plus.
