Volume issues with multiple clips

[davidra]

Functionally a newbie....I have TMPEG Author, which I've used for years to author, and TMPEG Enc. I'm putting together about 90 Youtube clips, all music, but the volume is tremendously variable; some are so loud they distort, some are barely audible. I've authored them into files. I've tried normalizing them individually with TMPEG Enc, and normalizing the entire disk at once, but still get tremendous variation in sound. Anyway to do this, preferably without doing each clip individually? I'm not sure why the Enc software doesn't seem to do much when I try normalizing the audio....

Hi!

Have you tried using an audio editor, such as Audacity or GoldWave?

[davidra]

I used to use Goldwave for pure audio clips....and dont know about Audacity.....but as I said, I'm a newbie....do I need to split the audio off to normalize it?

Hello.

My first thought, are all the youtube clips you have in flv format? avi format?

If you have the audio in a format that an external encoder can re-encode and normalize, that may be your best bet. I would recommend some programs, but I've been out of the loop well over a year :)

Good luck

That's my situation....I haven't needed any software in some time. I have the clips in flv and MPEG2, converted from flv with Super. Additionally I have the entire group of clips in MPEG2 in one file. What I'd like to do is normalize that one file....but it looks like that can't be done easily. I tried with TMPEG Enc but it just didn't seem to normalize very well.

Normalization isn't quite what you want, it's dynamic range compression. (Normalization can be a follow-up to this.) Avidemux has a limited capability for this, but has the advantage that you can load your video in, apply the audio filters directly, and resave without demuxing anything. You'll need audacity or another track editor if you want configurable & visual DRC though. Soundforge is one of the few that are capable of loading video directly, otherwise you'll need to use avidemux to demux it.

just split the audio and do everything you want with audacity.
audacity or audio editor won't recognize video files, so dont try
