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.

1. Navigate to nac.proisle.com
2. Enter the username Your First Name
3. Select Login

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 Project.

• Adding a New Book
• Import Project
• Sideload a Book
• Upload a Book

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?

• Set Play Order
• Tag Elements
• Export the Project (Pass to QA)
• Hand to Rachel
• Change Project Settings
• Remove the Project

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:

• Go to File
• Select Open
• Navigate to the file you wish to open
• Select the Open button

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:

• Go to Tracks
• Select Mix
• Select 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:

• Zoom in = command + 1
• Zoom out = 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 Pause, Play, and Stop buttons on the top-right menu above the viewer.

See this video for a quick demo on playing in Audacity.

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:

• Locate the section you want to create a separate track for
• Select it with your selection tool by:
  • Clicking at the endpoint where you want the section of this new track to end
  • Hold down your mouse and scroll over to the left highlighting the full section
• Go to 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:

• Rename the file to the name of the section. For example, your first track will be 01 Title Page
• Select the file type as MP3
• Create a New Folder named the title of the book to save all your files in.
• In format options:
  • Select Constant
  • Quality = 192 kps
  • Select Force export to mono
• Hit Save

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
• Genre = Audiobook
• Comment = Put the narrator here and enter it as Narrator: Firstname Lastname
• Save as Template to use it again for future tracks

You will then be taken to a window for Invalid Sample Rate. Change this to 44100 and hit the Ok button.

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.
