Audacity Forum

Found this that tell you about low and high pass filters. http://www.techbeats.co.uk/filters-a-co ... e-for-djs/

Basically how i would use the feature would be for splitting a song in to bass, middle stuff and Vocals. And then reducing the volume on certain sections to introduce new beats in the the song. So the standard dj low, high and middle pass filter setting as a preset would work for me.

Reading that webpage, this feature would basically be a visual Equalizer that have different effect on volume at different point on the track. So at some point in the song the bass could be turn down and a new bass line could be added very smoothly. Or adding a second vocal to a track could sound more natural.
On my friends Dj decks he has an equalizer that he can turn up and down bass and vocals and this would be same kind of thing in audacity.

I only suggest the presets as a guide for people who dont know have to do low pass filters and the like. (googling this doesn't have a great result)

Thanks

Edgar-RFT has written a plug-in that I use for years now.
You make 4 copies of your track and apply the plug-in. From a multi-choice you select the band that the selected track shall have.
It is simple but very useful to equalize in real time (with the gain).
However, it is in german and maybe no more "state of the art" in regard to nyquist Plug-Ins.

Hi

This doesn't allow you edit the volume of the frequency bands and it doesn't split them apart, but if you did it 4 time on the one track to get the 4 channels open at once it sounds ok but it not the best and there no cut off adjustment.

But im keeping that plugin

Thanks

Maybe a Thing worth mentioning:
You should inverse the duplicated tracks. Thus it is really easy to cut or boost each frequency band individually by adjusting the gain slider.
The cut-off freqs can be adjusted in the plug-in itself, but it's of course no Problem to put some controls into the GUI.
It is also no Problem to let the effect make 3 (or an arbitrary number) of inverted copies. The condition is that enough empty tracks are available. Nyquist can't not produce tracks of its own from the effect menu (only generate effects and only one track at a time).

What we are lacking is firstly tree-like grouping and secondly creating new tracks (or duplicates) just underneath the existing track - not at the end of the track list.

Hi

So the track grouping idea would have to be a feature added to Audacity itself and it would be very handy. But the audio frequency banding could be made into a plugin that could be installed by users.
Are there any tutorials on making plugins I can look at? I dont think im going to be making a plugin any time soon but Im interested how easy it is

I hope this idea doesnt die off because I think it will be a very power addition to audacity!

Thanks

I am sure that Steve can provide the necessary links to the tutorials if you can't find them yourself in the WIKI.
Learning by doing is the cheapest way to aquire new skills.
If you want, we can create the plug-in together - as a quasi-tutorial in the Nyquist Forum.
It is actually only a Task of Assembling already written parts and the documentation/explanation of those.
And there's the "design" of the graphical user Interface (within the known Limits).

That sounds like a good idea

There are major interface limitations for Nyquist plug-ins for this type of effect, but I'm sure that between us we can come up with something useful.
Robert, perhaps you would like to start off a topic in the Nyquist plug-in forum? (please post a link here if you do).
warfarsniper1, this is your idea so we'll be relying on your input from a user perspective, and perhaps you will learn a bit about how to make Nyquist plug-ins if you are interested.

@WC, I don't want to lose the idea of "group tracks"

Hi

Working to together on this is a great idea! and it will help me learn alot hopefully.
I will start with looking on the wiki for what Nyquist is and such so im not totally clueless.

The grouping idea should have a second post maybe?

Thanks

I've not forgotten about the tutorial, but other things have eaten up my time.
Sorry about that.

@Steve: I've added the group tracks idea to Wiki>PFR

And moved this thread to the "Audio Processing" section - with a link back here from Wiki>PFR
