Normalise a single track with many audio clips

[welby]

Hi,

I have a single CD track which contains a number of music audio clips but the problem I face is that the volumes on each clip varies.

I have no control over the supply of file so I need to get each clip at the same audio level.

There are no points of silence so I cannot segment each clip and adjust the audio level.

I really need to automate this from CD to MP3.

Does anyone have any ideas how this can be achived.

Short of the obvious and going back to the originator I haven't been able to achieve the result that I want.

Thanks in advance.

Rip it to Mp3, put it through VDJ using autogain and then record.

That is, if you use VDJ of course...

Thanks for the suggestion.

I thought VDJ analyses each audio track as it loads and then adjusts one audio level for the whole track

So if I play a single track with many audio clips it only adjusts the gain at the start and does not adjust as it goes through.

This is what I am experiencing - it's up and down like a yo yo.

What about some kind of gain normaliser?

There are plenty of free ones on the net.

Fire it into audacity and it will normalise it for you.

Yes - that looks promising

Some of these normalisers anyalyse the whole track and averages out the volume.

However I am looking for one that looks at the track as it goes through a brings up the quiet levels up and reduces the high volume peaks.

If that makes sense?

LASTAR looks promising.

Firstly you'll need to convert it to an MP3, then you'll need to drop the MP3 into an editing software I use Adobe Audition but that would but quite costly for just one job. Try http://audacity.sourceforge.net/ I think you'll be able to master each segment using that.

You're going to need to 'cut' the track into separate pieces and adjust the volume on each one so they match (as close as possible anyway) Then once you've done that you can play with mastering the track as a whole again.


I'm going on the fact that the volume of each segment are vastly different? If there's not that much difference, you may be able to adjust the track as a whole. Hope that makes sense. :)

if I had indivdual track for each clip I could do that, but this is one track with different audio clips running through it all recorded down at the SAME audio level, even if some clips are louder or quieter than others.

It's a bit of a conumdrum but thanks for the suggestion.

Mark - I can see where your coming from but these things are supplied to me at a rate of knots and I haven't got time to cut these files up.

I think I may have to go back to source and point out that their recording techniques "need to be adjusted" :D

But thanks for the suggestion.

Normalising is what you are after. It makes the track all the same level. Audacity will do that for you.

If you look at the track in audiocity the volume of the whole of the track is the same volume.

But what you really see is white noise filling the "quiet" parts taking the volume up to the same peaks all through the track.

If you normalise you will still have a track as for all intents and purposes already normalised.

Audiocity cannot normalise inside the mp3. You would have to take each clip in part and normalise (adjust volume) that part, which is not really practical when each track can contain 50 audio clips.

SuperMP3Normaliser can normalise inside an MP3 so this works, however it is a commecrial product, I was looking for something freeware.

Come on it's £15 !!! lol

Just to be nosey, what is it on the CD and why do you receive such bad recordings?

£15 ok ok! lol

it's rock n roll bingo - for some reason I don't think they normalise the tracks before putting them down to a master.

'House !!' remix ? ;)

I use Goldwave for editing, a bit footery but works great!
