Convert SUB to MP3

Understanding SUB and MP3 file formats

SUB files are typically subtitle files used to display text on videos, often in conjunction with a .IDX file. They contain time-coded text for dialogue or captions, but do not store audio or video data. MP3 files, on the other hand, are a popular compressed audio format used for music, podcasts, and other sound recordings.

Why convert SUB to MP3?

Converting a SUB subtitle file to MP3 is useful if you want to create an audio version of the subtitles, such as for accessibility purposes or to listen to subtitles as spoken text. This process involves converting the text in the SUB file to speech and saving it as an MP3 audio file.

How to convert SUB to MP3

Since SUB files contain only text, the conversion process requires two main steps:

1. Extract the text from the SUB file.
2. Use a text-to-speech (TTS) tool to generate an audio file (MP3) from the extracted text.
