  1. I’ve downloaded a series on video but from different sources but the audio levels are all different. How can I permanently batch set them all to the same level for playback on a tv? i'm also on a mac

  2. Thanks JVRaines. I should have added 'for playback on tv'. I'll correct the title now.

    Try the freeware Audacity audio editor for Mac?
    But that won't batch them, AFAIK. Not sure what might work for that on a Mac.

    FFmpeg has a loudnorm audio filter that you could use in a batch script.
