All right, I'm TOTALLY stumped here. Can't get my audio to

[etecnifibre]

resync with my video after I clean it up. It's got a pretty noticeable hiss, and I'd rather clean it up than put it on DVD as is.

Here is ALL the info:
It's an Mpeg2 file, 1 hr 41 minutes long, 5.1Gb, Variable bit rate, 8mbps max, target of 6.83mbps, audio, 160kbps, 48khz. Indiana vs Louisville from the 1993 NCAA tournament.

I've tried EVERYTHING. The file plays fine on WMP, and in Ulead Video Studio 9, Mpeg2VCR. I've tried every different way of cutting the audio, open the video directly into Goldwave, tried splitting it in UVS9 and creating a Wav file, mp2 file, mp3 file. I've tried all kinds of editors, all kinds of different paths of saving the audio, etc.

Can someone please walk me through the programs that you use to accomplish was I'm after? Or offer some insight as to why it keeps f@#$%n up on me?

Or, is there a video editing program that will allow me to apply an equalizer, or a dehiss filter directly to my audio stream? I just need to knockout the 12-20khz range.

I'm having this same problem, anyone have any advice?

Cool Edit Pro 2 and Adobe Audition have filters than can do this, even the freeware Audacity has a FFT filter that works well. You'd need to demux the audio into an LPCM WAV, then open it in those proggies and apply the filters.

Use DVDDecrypter to rip your m2v and audio file (using IFO Mode, and ticking Stream Processing etc), so you end up wit the VIDEO file plus the AUDIO file (ac3).

Is your audio ac3? If so, use the brilliant free conversion software PX3Convert to convert it back to wav. Then feed your wav thru whatever audio editor, and take out the hiss. Then convert it to ac3 with ffmpeggui.

"resync with my video after I clean it up. "

Generally not a huge prob. -- probably why it's not been mentioned so far. Normally might have to set initial audio delay, but that's minor and a big Might. The exception to the rule is if the audio's vbr mp3 -- you'll find plenty of posts on how to fix it if that's the case. And if it's ac3 or dts have to convert to wav as others have kindly posted already. If nothing works after trying methods posted, please post the format of your audio stream.

"Or, is there a video editing program that will allow me to apply an equalizer, or a dehiss filter directly to my audio stream? "

Some editors (most?) will let you filter the audio, if it's in an editable format that the editor understands -- no ac3 or dts. Or as many have suggested, strip it out, filter it, and put it back in during DVD authoring -- probably have to demux for authoring step anyway.
