Hey guys if i am going to put 6 songs together for an EP. all mixed in Cubase with noticably different volumes for each song..how would i normalize them all to have the same volume ( or close)? i knew my friend would put songs into acid pro and somehow make them all the same volume. but i dont have acidpro.. any ideas the easiest way to do this?

audacity.sourceforge.net and the compression plugin would be a good start...you can use the compression to manipulate volume.

Cliffriff,

Hit select all (Control+A), right click on any audio file, then go to 'Process - Normalize' in the drop down menu.

If your song are really varied in dynamics, just normalizing for volume might not help. You might have to compress or limit a bit.

yeah i don't think he wants normalizing really. what is the process again for using limiters and compressors for a handful of files? like, how do you match them?

If your going to go the maximizer or compressor/limiter route then you simply need to set up a set of presets or processor chain preset and use the same one for all 6 of the songs. That will insure that all are maxed to the same level.

I use the Rms statistics. If the overall Rms is say -14db, you limit to -4db. That leaves it at rms -10 (commercial loudness). Be warned that it doesn't always sound pretty at that level of limiting.

Do the same for the rest. If you have one that's -13, then just limit to -3 etc. Then just normalize to 99.5 %

You should have a something in your mixing software that measures Rms. If not, then there's some freeware around that does it. I don't have a link handy.

we need info on 'what stuff is.' we don't remember what rms is.

i want to bring up this whole normalizing thing again. for a long time peeps here always said 'don't bother with normalizing.' i was told it was basically stupid.

what has changed? now it's cool to normalize all of a sudden?

"Root Mean Square" I believe.

k but what does it mean and what is the consensus on normalization

lol, instant equations.

ok i'll look at it later.

RMS is Root Mean Squared. That knowledge and a buck fifty will buy you a cup of coffee.

RMS simply means DC equilivalant. DC power is constant nun fluctuating power. AC power (and audio is ac) fluctuates. When you average the power in a recorded piece you can do it using either Peak (or raw ac power calculations) or RMS (DC equilivalant). RMS is usually suggested.

Now that we know the answer to the universe and everything, lets move on to trying to use it.

As per WillBerry's post, the recomended method of setting a starting point for limiting is per his aforementioned post. Long low volume passages in the piece will have a tendency to render compressed resluts that will average out to less than expected if you run an analysis on the compressed file, e.g. as in WillBerrys example, if the piece had a lot of long quiet passages along with others that were significently louder, the result would be less than neg ten. Probably neg eleven or so. Remember we are talking relitive here neg 11 is quieter than neg 10. Psychologicaly, if followed or preceded by a piece that is blastismo throughout, even if the dynamically diverse waveform averages the same as the others, it may seem less loud.

In comes the good ole faithfull ear. Listen to the thing with other tracks and adjust as necessary.

On the normalizing thing. Most normalizing apps in recording software are not much more then a simple maximizing app with a built in limiting function.

What it does it as Walt stated average out the entire wave file be it a single track or an entire stereo mix. It then raises the entire track by a predetermined set point. Say you want a max level of -3dB then you simply set it for that threshold and it will average it out. If the max level it sees is say -10dB and the lowest level is - 25dB then it will end up with the max level at -3 and the lowest level at -18.

This is the simplest form of the use of it. Sonar for instance allows a little different take on this formula and you can run a little louder average and bring up the lower levels a bit more then the max levels if you so desire.

You see. There's a wee little button at the top of this page Cliff that says "tips".

Very helpful
