Macsome Audiobook Converter is an approachable piece of kit that enables you to turn audiobooks (AA and AAX format) into more user-friendly audio file types, namely MP3 and AAC. It's capable of removing DRM protection, supports batch processing, and requires that you have iTunes installed.

After a fast setup operation that shouldn't impose any difficulties, you are greeted by a clean and intuitive interface, made of a large window with a neatly organized structure, where you can add as many AA and AAC files to the task list as you want.

Audio information displayed includes the name, duration, artist, album and status for each entry. As previously mentioned, batch processing is supported, so you can convert multiple files at the same time to speed up the workload.

Before proceeding with the conversion operation, you can tinker with output settings when it comes to the destination folder, file format, bit rate, bit rate type (constant or variable), sample rate, and channel mode.

Apart from the fact that it can remove DRM protection, Macsome Audiobook Converter is capable of splitting files into smaller parts by duration, while preserving their original extensions. Plus, you can remove any item from the list or clear the entire queue to start the whole project from scratch.

The software application worked smoothly in our testing, without triggering the OS to hang, crash or prompt error messages. It had minimal impact on computer performance, using low CPU and RAM. Conversion tasks were carried out swiftly.

To sum it up, Macsome Audiobook Converter supplies you with a fast and effective method to converting audiobook files to MP3 and AAC format, backed by handy customization options.
