YouTube audio issues

[nitro_vip]

I'm new here so - hello to everybody.
I have crazy problems with audio in my video that I'm trying to upload to youtube. I have read your previous post regarding audio quality in videos, thats not my bigest problem.. Yet. The thing is that my audio is geting louder and quiter by itself. The tihing is that this particular video is nothing without at least decent audio.. After editing video that tooked me several hours finally I've got about 40 MB video of 5 minutes. I have crappy upload speed so it another hour to upload it. Finally when processing is finished, I was like WTF?! Audio is becoming louder and quiter - all video long! I got back at my PC, demuxed and start playing with 30 sec clip. I've tried various possible audio formats and bitrates, always get it crappy after processing.. Here is a sample at google video, the same shit I get at youtube.

Is there any way to bypass this so-called normalising? Its just not acceptable for me.
Thank you for your kind help and sorry for my bad English.

Unfortunately, I am not aware of a solution to the YouTube audio issues. I am a musician, and currently find the audio situation with YouTube to be unacceptable, so I am now posting videos at vimeo www.vimeo.com/keyboardwizard/videos

I've seen a couple of suggested remedies for the problem, have begun applying them myself, and they seem to work:

My sources are DVD and I've been taking the AC3, converting to WAV audio using BeSweet with HybridGain set, which keeps it from becoming too loud. Then I open the WAV in Audacity (free), create another empty track the same length and then Generate->Tone->Waveform=Sine->Frequency=30->Amplitude=0.1, followed by "OK". Then I select all three (the stereo music WAV and the Mono track with the Sine wave) and Tracks->Mix and Render. The Sine wave track gets mixed into the stereo track and disappears. Then Export that modified WAV file and do whatever else you want to it, like maybe convert to MP3. Mux with the video and then upload to YouTube. Or follow the instructions in that first link if using a different WAV Editor.

I have no idea why it works, but those loud distorted bursts are no longer there, and the audio sounds clearer, not muffled as before. Unless it's just my imagination.

Sorry for bumping the topic, I've been away so I didn't have a chance to check on the post. Thank you for your reply, I will try that audacity solution. It just frustrates me that this big website has this big issue. Have their coders ever tried to encode the damn video with ther "engine"? Its like buying Heineken and you can only open it with a freaking hammer. What a shame.

I noticed this today and uploaded a test. Well, they've finally fixed it. What took them so long to get the message as this problem has persisted since March when they started encoding with aac stereo.
