Newb begging your assistance

Jan 31 2012 | 4:08 am

Brand new to MAX. I simply want to take a mono music source and run it through various functions:

1) signal splitter
2) polarity flip (180 degree flip)
3) all pass filter (adj phase shift)
4) band pass filter (2nd order, 3rd order)
5) level control (boost/cut)
6) and signal summing

See drawing attached for an example.

I assume I can find all these functions in the MAX building blocks? I think I found an "all pass" block in the MSP Filters, and band pass ("filtergraph") and level ("gain") blocks in the "audio" section?

How about polarity flip? Summing? Signal splitting?

How to I actually get my mono music source into, and out of, MAX?

And how do I actually "connect up" the different blocks?

Is there an existing public domain program that perhaps has all these functions on screen and ready to use?

Many thanks in advance.

see the little gray boxes around the edges of the big boxes? click on one, hold the mousebutton down, and drag to another.

Then read the documentation on Max and MSP – all the documentation

Another hint, for future happiness – figure out what that stuff does before trying to build it in any other environment.

A polarity flip? isn’t that just *-1-ing a signal, or would that be too simple?

sure it is. But I doubt whether he’s at the level where even that’s of any use.

"figure out what that stuff does before trying to build it in any other environment."

Exactly – that’s why I’m attempting to do this virtually rather than on a big analog breadboard.

I do know what each individual function does, thanks. Thirty years audio hardware design :-), but brand new to MAX.

doing some spatial/surround filtering?

I second @jamesson – go through the tutorials, this way you’ll learn how Max works and then you can do what you want.

If you think the tutorials are too long, I can guarantee that the time it will take you to just copy-paste our examples and keep coming back to the forum to continuously ask for help for every little thing you want to change/try will be far more than the time it will take you to read the tutorials and learn how to do these things yourself.

Max is a complicated platform – there are no shortcuts. Or you can ignore this piece of advice and spend a lot of time (and cynical responses in the forums) figuring it out yourself.

Sorry if I came off as dismissive, driz – you said newb, so I assumed that applied generally.

I’m hoping to transition into your direction myself actually – could you pleas tell us more about yourself and/or link to your work?

noob_meister, that’s awesome! thanks so much. can probably do what i need from there. yes, experimenting with some "spatial-like" filtering on a mono signal :-)

no doubt this will inspire you to read the docs and helfiles, then do something a little more sophisticated!
