iTunes is the most popular source for buying or renting digital media files. But you may not know that it also has many wonderful functions. It can convert audio files, burn iTunes to CDs, transfer files and more. With iTunes, you can have iTunes detect your MP3 files as audiobooks. Alternatively, you can convert MP3 to audiobook formats like M4B. Now, follow the steps below to understand how both methods work.

Part 3. How to Convert MP3 to Audiobook with Audacity

You can use Audacity and Audiobook Converter to compile an audiobook with distinct chapters from your MP3 files. This approach involves dividing the MP3 file into smaller chapters using Audacity, and then combining them into a single M4B audiobook file with Audiobook Converter. Although it might take some practice, the following steps will guide you through the entire process.

Step 1 Download and Install Audacity

Make sure you have the latest version of Audacity installed on your computer. You can download it for free from the official Audacity website.

Step 2 Open the MP3 File

Launch Audacity and go to the File menu, select "Open", and import the long audio file you want to convert into an audiobook. This process might take some time depending on the length and size of the file.

Step 3 Find Chapter Intervals

Use the zoom tool in Audacity to zoom in on the audio waveform and look for natural breaks or pauses that could signify the beginning of a chapter.

A more efficient way is to use the “Silence Finder” tool under the Analyze menu. This tool helps locate moments of silence in the audio file, which can indicate chapter breaks.

Step 4 Adjust Silence Finder Settings

Set the minimum duration of silence to around three seconds, which is usually a good starting point. Adjust this value based on your specific audio file to accurately find chapter breaks. Leave the "Treat audio below this level as silence" setting at 10, but you can adjust it if necessary. Set the label placement to “0 seconds before silence ends”.

Step 5 Review and Edit Labels

After running the Silence Finder, Audacity will place labels at detected silences. Review these labels to ensure they mark the correct chapter breaks.

If Audacity marks incorrect silences, right-click the label and choose “Delete” or drag the label to the correct position.

Step 6 Name the Chapters

Click on each label and rename it to match the chapter titles. For example, the first label can be named “Introduction”, and subsequent labels can be named “Chapter 1”, “Chapter 2”, and so on.

Step 7 Export Chapters as Individual Files

Once all chapters are labeled correctly, go to File > Export > Export Multiple.

Choose “Split files based on labels” and ensure that the option to use labels for track names is selected. Specify the folder where you want to save the files and export them. Audacity will ask for metadata tags for each track, which you can fill in as needed.

Step 8 Merge MP3 Files into M4B

1. Download and install a software like "Mp3 to M4b Converter" or "Audiobook Binder." These tools are specifically designed to merge MP3 files into a single M4B file.

2. Open the software and import all the MP3 files you exported from Audacity.

3. Arrange the files in the correct order if needed.

4. Configure the settings such as book title, author, cover image, and other metadata.

5. Start the merging process to create a single M4B file. This file format is supported by most audiobook players and allows for better bookmarking and navigation.
