These days, a lot of people have decided to leave behind heavy paper tomes and move into the digital world. It's understandable, since storing thousands of stories on a hard drive is much more convenient than filling bookshelves. However, when you have so many files, things get complicated. it can turn into chaos if you don't have a decent system to organize all that data.
To solve this mess, Calibre comes into play, an open-source tool that is completely free and lives up to its reputation. It's not just a program for organizing folders, but a comprehensive management center which allows you to read, convert formats and, what interests us most today, take advantage of technology to listen to your readings.
The native text-to-speech function
To use this function, open the book with a double click and, once inside the Calibre viewfinder, Press the Read Aloud button (Read aloud) from the control bar. Playback will begin from the current position, and the program will highlight the text as it progresses. While reading is active, you can access the settings menu to change the voice. Select the text-to-speech (TTS) engine and adjust the playback speed according to your preferences.
The best part is that you can customize the system to your liking. The program lets you change voice and language of the content, so it doesn't sound like a strange robot. Also, if you feel the narrator is going too slowly or rushing, there are buttons to modify the reading speed in real time, adapting it to what best suits you at any given moment.
Using TTS add-ons and plugins
Sometimes, immediate playback isn't enough, and we want something more permanent, like a sound file. For this, we can use extensions. One of the best-known is the plugin. TTS to MP3which basically converts the book's text into a downloadable audio file. This add-on is a godsend, especially for people with visual difficulties who need to access content without relying on sight.
To install it, the process is simple: download the ZIP file from the official website and then, within Calibre, go to Preferences / Add-onsThere we select the button to upload plugins from a file, accept the security warning, and we now have the new button. Create MP3 ready to use in our toolbar.
Management of real audiobooks in the library
It's not all about converting text; sometimes we already have the audiobook in MP3 or M4B format. The problem is that Calibre is designed for ebooks, not music. A very effective solution is to use the software... AudioBook Converter to convert the files to M4B and then use the M4B metadata reader so that Calibre can recognize the book information correctly.
If you configure the player VLC as defaultYou can launch the audiobook directly from the Calibre library, even maintaining chapter support. However, be mindful of storage space, as these files can be quite large. occupy from 50 MB to 14 GBThis can saturate the disk or complicate cloud backups.
Tips for optimizing your audio library
- To prevent the main library from becoming endless, some users choose to create a portable instance of Calibre dedicated exclusively to audiobooks.
- Since Calibre accepts almost any format if it's a single file, it is recommended compress the audio tracks in a ZIP or RAR file to maintain order.
- On modern eReader devices, remember that you can link Bluetooth headphones to enjoy the wireless experience, managing the speed from 0,5X to 3X.
