Crash normalizing and bad subtitles generated.

[Dikakus]

Make sure you have read the readme, searched and read the issues related to yours. Otherwise it will be considered as a duplicate which will be closed immediately.

Describe the bug
Launching a subtitle creation from an flac audio with preprocess, throws an error normalizing due a bad value of a parameter and autosub crashes finally.

To Reproduce
Launching with preprocessing.

• Command line arguments you are using.Use the following markdown code block syntax is recommended. Copy them into the place between ```.

autosub -i DdL1x01-2.flac -S en-GB -bm s -F srt -ap y

• A complete copy of command line output of the autosub. You can use Ctrl-A and Ctrl-C to copy all of them.

It seems that your audio file is too small to do the processing.

[Dikakus]

The input flac file has a duration of 24 min!!! I can listen to it in a player. Could something in the preprocessing be cutting it?
