how to use "Stretch by" option in mkvmerge?

[tomos]

i have no idea how to use this. the only things that show up in a search is using framerates which doesnt apply here. the guide i found says to enter a 'floating point number' which is as clear as mud - there is no example of how to use it at all.

can anyone please advise what to enter if i just want to stretch the audio by 2 seconds?

thanks

1.0, 0.5, 3.14159, 2.71828 can all be used as a floating point number by a computer. Perhaps the docs should say decimal or fraction. To stretch by 2 seconds you will need to know the length of your audio and then fill in the correct values in: audio_length+2/audio_length. E.g. if you audio was 60s long then you would use 62/20.

shouldnt that be 62/60?
