Appends sample frames to the specified audio track.
Keep the number of video frames and audio samples aligned so that each track is syncrhonized as much as possible. For instance, a file with 30FPS video and 48KHz video, each addition of one video frame should be followed by the addition of a buffer of 1600 sample frames.
