I have a wav file named as a.wav.

Let's say it is 9.432 seconds.

I want to extend it to 13.321 seconds.

So I need to add silence to both beginning and end of video to 1.945 seconds.

The reason is I am working on a TTS application and I want to generate entire speech from a given subtitle srt or vtt file

So how can I do this perhaps with ffmpeg?

What command should I run?
