Probably been addressed here before: I wish to improve the audio part of a video, e.g., increase the bass, turn on a little reverb, and whatever else can be experimented with....and then store the final audio back into the video as its audio. Can this be done somewhat straightforwardly (e.g., using some particular software) or is it even possible (i.e., for a non-sound engineer)? I realize the audio resides on one track (right?), but I'm thinking that still leaves some opportunity for improvement. We encounter so many videos on the Web that have horrible audio....and, then, others have great audio....what makes such a difference!! Any suggestions would be greatly appreciated!!
