You can speed up or slow down audio with the atemto audio filter.The atempo filter is limited to using values between 0.5 and 2.0 (so it can slow it down to no less than half the original speed, and speed up to no more than double the input).To slow down the audio to half of its speed we have to use atempo value 0.5. For example, if there are two succesive frames shown at timestamps 1 and 2, and you want to slow down the video, those timestamps need to become 2 and 4, respectively.Thus, we have to multiply them by 2.0.
