Use Trim () to remove the extra video frames. This will double the playback speed of your audio and resample it to the original rate.

rate = 2 # double the speed of the audio
AssumeSamplerate (round (audiorate * rate)).SSRC (audiorate ())

Hello
the audio was a little too fast for what i needed
so i tried playing around with the assumesamplerate filter
i discovered that i need to put the sound up to 96000 Hz
thanks for the help anyway
