I read http://designingsound.org/2013/06/tutorial-a-compressor-in-pure-data/ about compressor working and I tried 3 different (or similar) compressors: the one from the page, the one from DIY2 by Hardoff and the one from rjdj by Jwif. I thought that compressors works different...
I use visual arrays to see the difference from the original sound (that is very loud) and the compressed one. With the first compressor, there was NO DIFFERENCE. No at all... I don't know if I was using wrong, but it was the same graphic. With DIY2/st-compressor.pd, there's difference and it seems to be good... untill I make a kick. Again, the waves goes to the sky (well, not so much). The third compressor can compress a lot (low threshold), but all the rest of the sound does too.
I though that only the sounds that are higher the threshold are compressed and the rest stay the same. Am I wrong? Am I confused? I thought that a compressor is like tanh(), but with editable controls.
Can someone explain this to me?

But, our economy is fatal. One dollar is ten argentine pesos. I bought this computer 3-4 years ago, at ARS $6.000. Think spending U$S 6.000 in a computer. Now, a good computer, is above $10.000.
Then, you haven't picked the right computer for your composition :)

ask 4 persons and you probably will get 4 different answers. first thing i would notice the setup seems dirty. for example use an external preamp instead of digital amplification (e.g. *~4) if you want proper sound quality. secondly i think you should try out and trust your ears. it really depends on what you want it to sound. tanh most probably will lead to more distortion while compression will eat more cpu.I will use a wireless system with this mic, so, it has gain. I'll check that, because I think that it is important a preamp there.
to avoid your kicks being louder than vocals you should refer to beatboxers. maybe you do something wrong there. or you should use 2 mics. i admit i am not familiar with mixing rappers who beatbox at the same timeThe mic is very good and it sound very good. I want to clarify my doubts, because I "see" waves beyond 1 in visual arrays... and I want to understand that.

Now, I am checking volumes of my looper patch. I had to raise [*~ 4] the volume of the mic, to get a razonable volume, compared to a song file, for example. But, using this looper patch, I make beatbox. So, kicks and snares from my mouth get in the mic. And, using a visual array to test it, I realize that the kicks and snares are so much higher volume than the vocals.
The patch has FXs with feedbacks, so, they can make signal > 1. So, at the end of the patch, there's [expr tanh($v1)] to to avoid that... tanh() is simpler than a a compressor, but it loose some sounds (I think). Or I should trust in tanh()?
Multiple choice:
1- Use tanh() in the input, after adc~ and before dac~.
This will cause distortion and change the shapes of your waveforms, and introduce extra harmonics. It may be an interesting effect, but it will change the sound of your beatboxing.
2- Use a compressor patch in the input, after adc~ (and tanh() before dac~)
This would be the preferred method.
3- Use a compressor at the end of the patch, before dac~
If you have multiple instruments or voices in the output, you'll be decreasing the volume globally and throwing off your mix.
4- Stay as it is now...
Also, I can't spend more CPU process...

Really, I don't think compression should be a cpu-expensive process. Plus, you have only one mic, right?
What do you recommend me to use?
Thanks.
