Audio Processing – Probably Simple!

Jun 08 2011 | 10:44 pm


So I’m new to Max, this is the first project I’ve done and I’m struggling! What I’m basically trying to do is record a vocal in, and then put it through some effects and save it at the end. I’ve got the recording part fine, and I now want to put it through some kind of EQ (I have Filtergraph up) and Live Grid. But I’m not sure how to link them up! The audio is so far going straight from (open) and a toggle switch into sfplay~ and then into some gain meters, so how can I link it to filtergraph etc and have the resulting audio play etc!

Any help would be Massively Appreciated :)

I don’t know much about Live Grid, but it sounds like that is a UI object only just like Filtergraph. The easiest thing would be to open up the filtergraph~ helpfile, and copy straight from there the biquad~ setup(you’ll want to send your audio through biquad~ which will be controlled, graphically only, by the filtergraph).
OR, if you’re feeling adventurous, look at the helpfile for cascade~(cascaded biquads, the amount is your choosing). You could easily setup a multiband parametric EQ this way.

The resulting audio will be coming out of biquad~(or cascade~), since they are the ones doing the actual audio processing(filtergraph only outputs coefficients or numerical data for filter control-parameters).

[Edit: also try posting your patch so far here, select all within your patch, under the Edit menu in Max, choose "Copy Compressed", and then paste from your clipboard straight into a forum post here. people will be able to give you hands on help that way.]

Wicked, working great so far! Do you know how I can also show the waveform of the recorded file? Doesnt really matter whether its pre or post EQ, just needs to be in there!

waveform~ ?

Tried that but can’t seem to get it to work! If its coming out of a gain metre where would I go out from it and then in to on waveform~?

(ha, there’s no tutorial involving waveform~ i don’t think… another thing you have to learn using helpfiles… see waveform~ helpfile about linking to a buffer~…simply set the buffer’s name in waveform~’s inspector…)

you’ll have to load the file once the recording is done into a buffer~ to see it in the buffer-linked waveform~ view.

@ Noob4Life

can I PM you a link to my PhD blog? Please.
Lots of sensor hacking, coding/patching, interaction-design goodness with a slight hint of n00b-osity.

sure. (do we have PM on these forums?) i’m too scared of everyone(in the whole world) to give out my email here. :p
Why not start a thread about Brendan’s PhD blog in misc section? All the forumers here would probably concur that you are a valuable part of the community, would probably love to see what you do?

That’s a better idea; will do
