goldwave help

[natty]

I dont really know if I am explaining this right but here goes

ok i done a video of my family with my cam corder. it was a mpg then i converted to vobs so now it is as a VIDEO_TS and a AUDIO_TS folders but when i play video about 10 mins of audio is way too loud, at the start, then rest after that is well low so how can I take beginning bit off and make it softer and then rest to make louder then eventually join up as 1 perfect audio with right volume. this sounds a bit complicated i know so sorry for that hope someone can help and understand what i mean

thanks all 8)

EDIT: ok I think this ? is a bit confusing if I say so myself but basicially how do you lower the volume at the beginng part of an audio file and increase the rest using goldwave

Extract the audio and use the normalize/equalize (I can't recall exactly) feature. It will sample the entire audio track and then make it the same level.

You need to shape the volume. Goldwave can do it, but it is sort of clumsy. I haven't tried it yet, but I imagine that Audacity has a better volume shaping tool.

are you on about goldwave as where is normalize/equalize

I see on goldwave where shape volume is but what do I do

please can someone help me here

I don't know about Goldwave, but I've used Audacity to do this before. Look at the "Envelope" section here for instructions:

https://wiki.brown.edu/confluence/display/CISDOC/Audacity+Tutorial

I'd imagine Goldwave has something similar, but Audacity is free and is very highly regarded if you want to try that. Depending on the type of audio in your VOBs, you may have to convert it to WAV first (after you've extracted (demuxed) it from the video, as Krispy said.

I seem to recall a short cut button in the main toolbar and it can be reached via the menu, under tools I believe.

when I have done the audio what do I use to put it back to the video and have it in sequence right to the vid

I dont see a short cut button under tools

I fired up a GoldWave trial to check it out. Here's how it looks like you would do it:

Load your video, then click "Effect", then "Volume", then "Shape Volume..."

In the box that pops up, you can tick the "Show envelope" button to give you a picture of your left and right channels to better guide you visually on where you are in the track (the red and green graph on the bottom of the picture below). Now just click on the line in the center at 1.0 to set a control point. Move it up or down to raise or lower the volume. Click to set more control points and move them around as needed. Note that the graph on the bottom does not change to reflect your volume adjustments, it's just there to show you where the loud/soft parts are.

In the example above, I've dropped the volume down to almost nothing between 30 seconds to 1 minute, then went very loud for the next 30 seconds, then back to 1.0 at 2 minutes to put things back to the original volume.

To preview your work, click the "Point" box back to 1 and hit the play button on this window (setting the point to 1 starts the preview playback just before your changes begin; you can adjust that if you want to check a different change further along in the track). When you get it like you want it, click "Apply" then save it.

ok thanks will give both goldwave and audacity a try

[dphirschler]

Volume shaping is simply drawing a line across the audio wave. The higher the line, the louder the volume. The lower the line, the lower the volume. Goldwave gives you a zoomed out view. I always found it difficult to get really precise with it. But Cool Edit Pro lets you zoom in on the audio and put the line segments exactly where you want them... down to the sample. I'd imagine that Audacity lets you do the same thing. It see,s very similar.

Audacity lets you see the effect of the envelope on the waveform so it's easier to match up peaks, etc., as you draw the envelope. I didn't see an option for that in GoldWave; you'd have to adjust by listening/trial-and-error. I'm not a regular GoldWave user, though, so I may have missed it. Audacity:

Try the Goldwave forums for much more info. I've used it every day since 1995, with great results.

I want to thank you guys for this post. I had a cassette tape suffering from playout (where the sound gets really low and loud at points) and was wondering if there was some better way of fixing this (normalization did not work). I had no idea what Enveloppe ever did (I use sound forge), now I know, and can probably best fix my tape with the
methods you listed above--
