Title: Making my song louder
Post by: Reenen on November 28, 2006, 09:09:19
My experience is that I have to turn my volume up when I listen to my .it files...

How can I make my song's volume louder?

The tutorial says this:

Now, you may notice that the bass sounds OK, but could be a
little louder...  There are many ways to fix this, but the
easiest by far is to simply copy the information into another
Channel.  Copy Channel 4 into Channel 5 so that the two are
identical, and play the pattern again.

Any other ways to make your *whole song* goes louder?  Because compared to my MP3's my .it files are very faint.

I would not suggest to copy the data to another channel unless you really need to.

It is logical that your mp3's will sound better than your IT files because those mp3's are mastered. Its the mastering that finalises them for the proper volume.

To make your IT louder, here are some techniques to try:

Ah... ok, I think it was my instruments that were on 64 (I think it's the default from the GM.dls file).

I've made such suggestions in the past too, but you're absolutely right. It's a last solution if nothing else helps.

Sometimes normalizing a sample hardly makes a difference, because it contains some high peak(s). A limiter is indeed the answer to that.
Besides VST-plugins to achieve this, there is a small external app. to compress samples also : Peak Limiter (http://www.x-ways.net/peaklimiter/index-m.html) (shareware).

I suggest you to use a compressor on samples that need more punch. You can use a compressor VST, directX's VST or directly compress you sample with an audio editor like Audacity  ;)

Also, on the subject.

Make sure you have Mixmode RC3 for the best volume setting. Might do wonders. RC2 is very faint, unless you play with the assigned volumeslider in the setup screen. Changing to RC3 is still a better option though.

You can do this by going to the general tab, song properties.

Please note that mixmode RC3 is enabled by default for new modules, and upgrading from any of the other mixmodes can break your module, especially when working with VSTis.

Ah yeah.

Sorry, forgot to mention that. :) This is one of those efforts, in case you want to fix a module but not want to destroy the dynamics. This mostly affects if you want to playback a song in OpenMPT instead of another player.

  • In the general tab, put the global volume to 128, and the preamp to about 33% This way you have the optimal setting. (a higher preamp can give a wrong image of your sound when mastering your song).

As OpenMPT stores in the .ini file the preamp value, What is the best or default value?

What is the best
Obviously the default value (PreAmp=128 in mptrack.ini), since that's probably what most people use.

I disagree completely.

As stated earlier, using a preamp value of around 33% gives the most balanced feel. But even better is to not use it at all by using mixmode RC3.

The science behind using 33% value is based upon that somewhere in the code when using RC2, 33% is set to be 100%. This can be noticed when using DX effects in your song. They're set to the max, which can be influenced by the preamp setting. Going lower than 33% and you'll see that it never peaks out to the max. Going over it, and you'll hear that it destroys your audio.

I've found that the same can be heard a bit with normal plugins too, but its not as clear as with DX effects. For that reason, I brought this up with Rewbs and Atlantis some years ago, which is when the entire mixmode discussion started.

Uuuuuuuuh excuse me, but 128 is exactly one third on the slider. :P

In that case, my apologies :) I misread you because most people use the default volume probably which is all the way to the top.

128 is a weird value for being at 33% though, that would mean the max value is somewhere at 385.

That is because the formula that is actually used for the pre-amp does not reflect the slider in the configs dialog; It would indeed be a weird value if 0 was silence, but it is not. The comments in the source code say that the slider range is "approximately +/- 10dB". From the original number (128 in this case), 64 is subtracted and then it's divided by 8. The slider range is [0...40] then.

It seems that the value I am using, which seems optimal for OpenMPT is 176 in the ini.

Well, that is what you perceive as optimum, and not what is the optimum for sharing songs (which you don't do anyway). In that case it is of course always preferred to use RC3, but since most people have probably set this to 128, the best is to leave it as it is.

Some additional information: With the next release, there is going to be a new mix mode, which is designed to be more compatible with other trackers. It's basically the same as mix mode RC3, but with soft panning disabled (this is forced, as it creates a completely different stereo spectrum) and slightly lower mix levels. This will be the default mix mode for MOD/S3M/XM/IT (you can't choose the mix mode for MOD and S3M, actually).

Which mixmode will the MPTM format use? RC3?

Yeah, since we don't really have to care about compatibility there.

Being a purist I absolutely hate to say this, but look for a limiter plug-in on KVR which, basically, reduces any volume above the threshold to the volume set by the threshold, after which you can increase the average volume. So if your limiter has a threshold of -6 dB, anything over this will be 'limited', or reduced down to this volume, giving you a smaller dynamic range overall but a greater average volume. This is the basic idea behind mastering - to make things louder by decreasing the peak volume, while increasing the average volume. That being said, mastering is one of the last things you sould be looking at and there are tons of techniques of increasing the average level of a mix, compression being one of them. Just work on making your songs sound good - not loud...

Btw, LPChip, I can't believe you still have me quoted in your sig. ;)

Classic Limiter is a simple but effective limiter. I'm not sure where you can get it since the Kjaerhusaudio website seems to be gone, but I bet there are other sources as well.

Hey Atlantis! Great to see you here after so long. Yeah, I love quotes enough to keep them for some time. (Jojo knows all about it. He even refused to me the signature limit long enough for me to keep a quite about him in it :P Which was outdated actually)

I use Buzzroom BuzMaxi for a limiter, which I think works really well Very easy to use and very powerfull in what it should do.

See: http://www.x-buz.com/BuzMaxi3.html

Wait till you try the Waves L316 or L3-LL... I'm still scared running my mixes through them they're that good. I know they're expensive and all but I'll keep trying before buying... I'll also try your suggestion when I actually have a mix worth of compressing.
Title: Re: Making my song louder
Post by: LPChip on November 16, 2010, 13:08:20
Please let me know what you think. Especially if the waves one still is far superior, I'd like to know about that. :)

Thus far, I haven't found a limiter this good, but I haven't bothered seeking past the free ones either.
