Uhhh... Two things!

Okay, so...
Lately, I've been like, a little down because I know I'm not knowing something.
I figured out what this something was.

Voice effects.

Like, two hours ago from this post, I just re-released "Butterfly On Your Right Shoulder," and I noticed that... the effects used on the original singer's voice (Rin's, as far as I know) seemed almost "un-guessable," really. I have absolutely no idea to get any of those effects at all.

So the first question is: how exactly does one yield the more electronic/artificial effects on the UTAU's voice? Is this done in UTAU, or in a sound software?

Second Question: I'm getting a little annoyed at the sudden quiet notes, and then the sudden ear-piercingly loud "RAWR" notes that occur when I play through a song with my UTAU. Any way to fix this?

Thanks, guys! :D

Oh, and... <- My version.

And...

<- Rin's version.

For the first, I know some people add special effects (like reverb, echo, etc) with outside programs. Audacity is one of those, being free and customizable on that aspect.

Also, there are the harmonies. I understood them not long ago (I have not much musical knowledge) so I can't tell you much but it's like a duet you make your UTAU to do with itself with the secondary voice with a difference of usually of +12, +7 or +5 semitones. Each of them can also have one of those of less value (so the main vocal can have one at +12, that +12 has one at +7 from it and that +12+7 have another one +5 from it so this last one is +12+7+5 from the 1st vocal). Hmm, not sure it this will help you much.
I started researching them after I saw this tutorial so maybe it helps you a bit on that:

I hope somebody else helps you on this 1st question as I don't know myself.

About the 2nd thing it comes from using resampler.dll.
Not long ago it was found a fix to use resampler.exe on any computer so you may want to check it if you can't make resampler.exe to work properly:

But take in account resampler.exe can't use hiragana voicebanks in a not Japanese locale (even if using AppLocale)... but oh, well, not Japanese locale gives a lot of problems with those voicebanks anyway.

Oh, hey! Thanks for the help.
Oy...
I feel dumb for not knowing ANY of this at all. xD
Though I had a feeling that harmonies had something to do with it... Only a little, though. Didn't know they were this pivotal. o_o;

I edited a bit the 1st post because I really don't know much of harmonies and I think I did it wrong the 1st time. I hope you read it.

-Read it.-
o_o
I am SO lost... xD
If only UTAU had that back-up singer option that VOCALOID has... That'd be so epic. Dx

Yeah, making harmonies with VOCALOID is very easy as it has the option of various tracks.
You can see a bit how it was done with VOCALOID2 here (but chorus/harmonies is by another voice instead the same singer, I think). They're in the part were they say "sweet Caroline":

With UTAU we can only mix the harmonies separately using something like Audacity, Reaper or whatever you use to mix the music and vocals.
Oh, be careful doing harmonies as they can end doing clipping to the sound.

In this wavetone tutorial/demo shows how harmoonies "look" in 1:44

(I wish somebody else could help you better with these things of sound effects, sorry for the bad explanations.)

Clipping...
Uh...
What does that mean again? orz

For harmonies... hmm. You know chords, right? It might be easier to think of it as if the "main singer" and the "backup singer" were making chords. Obviously, you can't sing more than one pitch at once, which is why you need two people for it. owo For example... I'm going to play practice now but I'll explain a little further when I get home. ^__^;;

Graphically is something like:

(Image from here.)

It's when the sound goes overlimit.
If you have two normal waves with a normal amplitudes and you add together can happen the final wave to have an amplitude over the limit. The software to prevent damage just cuts the wave so there is no part over the limit as you see in the image and then the sound sounds differnt and awful.

To stop that, you mix the waves with a lower amplitude in the part where it would clipping, or something like that. To tell the truth what I do is to lower the volume of everything (so even if they add they don't reach the limit), mix it totally and amplify the semi-final ended wav later to the max without clipping.

I know what harmony is. xD I just have no idea how to incorporate that with making a .UST...
In fact, I don't even know if I have the capacity to make those. Looks really hard to do it by ear! D:

Hm... The clipping thing, I think I sort of understand, though I have no idea as to how to prevent it. :/

Ohhh! Sorry! ^__^;; Basically you need to make a separate UST for the harmonies and put them together when you're mixing. It really helps to have a good ear for hearing parts but it gets easier with practice. owo

For making it not clip, COMPRESSION COMPRESSION COMPRESSION. Sometimes if you just lower the volume in general, some of the quieter things can get lost. Compression evens out the volume, if that makes any sense (only do it to your vocal tracks, though, don't compress your karaoke!). You probably will still need to lower or raise the volume to get it just right.

Also, depending on what you're using to mix, there'll be a volume meter somewhere on the control panel (I think it's across the top-ish area in Audacity, if you're using REAPER it's on the left... with the volume controls, which is nice XD) It shouldn't constantly be filling all the way up when you're playing back your song. If it is, lower the volume or mess with the compression until it doesn't. It's a little trial-and-error sometimes. owo;; Hope that helps!

I understood that! I still don't know if I'm right for making .USTs, though! xD
Thank-you for the help. oxo
