Topic: Can we catch the level of the sound?

Dieses Thema ist veraltet und kann veraltete oder falsche Informationen enthalten.

some effects uses the level of the song, for example vocoder.

Does a variable exist in vdj to measure the level of the sound?
For skin for example this kind of variable is used for bargraph.

I know you can get the volume of the song with Getparam() + volume . I mean the volume written in the VirtualDJ Database.xml and not the position of the slider level on the skin. But i don't really know what is this value "Volume"

It's the overall volume of the song. I think deun deun looks for the momental level

Hmm maybe code it yourself

have a buffer of x samples
count the absoulute value of each sample together (so negative nubmers will be positive)
and devide that big number with the X. You will have the aproximate level
of the song for the particular block.

Waou incredible !! where have you learnt that? You seem better known plugins than me lol

LOL, You must be kidding.
But more brains = more knowledge.

But some info's I have, have two meanings and I don't know if I get the correct meaning always.


And you mentioned it is info from the xml. The only volume from the xml is the one from BPM analysis.

I activated your plugin this night after testing it. Thank you very much for it.

After trying to guess how to do that (i was surprised as we hadn't functions for that) , i think i found: only put a minus just before the int of the sample. It was very clever an tell me if i'm wrong ;-)

MAKECHAN(l,-r); for each sample?

I agree with djcel : we met an expert !

thanx for your advice

Thanks.... sourcecode is uploaded too,
but i had some problems with assigning values so I used temporary values.

Samples are from -32768 to +32767 so it is

temp=-1-right_channel;

in order no to have invalid value +32768 on output.

I just finished testing HDJC mapping. Will post to hardware forum.

yes you're right: the function LIMITER(u) cuts at 32768. I forgot that detail

Maybe you don't know it but in the function OnLoad() you can write (it's the same in C++):
//////////////
prehod=false;
invertuj=false;
///////////////
instead of
////////////
prehod=0;
invertuj=0;
//////////
You also forgot the function LIMITER()

I have just improved your source code by removing a lot of useless things. I will send it to you like that you can have a look on what i changed and so improved yourself and at the same time update the .dll file and .cpp on the website. Use the link modify next to you plugin

I'm currently reworking it to do it binary ;-)
and also will use english name for variables.

Yes sometimes i forgot to write my commentaries in English in the cpp file because it's easier for me to write them in French. You will see when you wil become experienced after releasing some plugins ;-) Don't worry we are here to help you like we did for Deun-Deun

djcel, do not forget to remember Lopez this kind of French sentences: "y qu'à, faut que, facile "and the incredible "il suffit de" .... :-D
 

geposted Tue 14 Jun 05 @ 12:43 pm
Uploaded new version (source and dll)

reworked audio part ... have a look


Btw. limiter was not necessary int the previous (1.0) because I did no math operations that
could lead to greater numbers than allowed (thats because -1-chan so it will stay in -32768 to 32767)

btw. What's the translation of Deun Deun's french sentences ?
babelfish did not help - i didn't understand:

"there that for, is necessary that, easy" and the incredible "it is enough to"

In fact when i started to explain him plugins, i used some sentences which express idea that things were easy to do lol
He is laughing at me
Besides, your code is now very clean :-) Go on like that among us
