Dear MaxMSP users and gurus,
I am an interaction design student and have a project as an interactive sound installation. I am using a motion tracking software, Eyecon, to detect the movement on 5 fields in a room. Each field refers a audio sample that will be activated by the movement of the users on that field. For example , if the user walks from right to left on a field the pitch of sound samples will be effected, or the echo will be heard.
In order to play the sound loops I am using Maxmsp. I would like to add more dimension to the sound output. and to make the output more playful for the user.
What do you suggest me to modify in my sound samples? which objects or opensource plugins can I use?
Thank you very much,

Do you mean that there will be 5 people, one for each field?

You could have one user adjustable parameter be a resonant filter which sweeps as the user moved around. For this you could use [svf~] or [reson~] and modulate the center frequency.

You could have a flanger with the time delay set by another user. For this you could use [delay~]. Or go to maxobjects.com and search for a flanger and/or chorus. There's probably one there.

An obvious one would be to adjust the tempo.

Can't think of anything else.

Speed/depth of amplitude modulation; frequency/speed of a stutter effect; amount of overdrive; etc. any effect, any parameter, experiment - see what you like.

homig, just take some kind of audio software and try creating the sound-fx you wish to have there first. This would give more of an idea, what exactly you need to implement in max/msp.
"Dimension" itself is a word which could mean anything, really, depending on taste and experience.

However, as an add-on to my former posting you could

simply restart the sampled audio in one of your 5 fields upon user movement, leading to the person realizing that to stop movement to be able to hear the whole piece of audio in one go.
You could as well apply some randomized pitching/panning/filtering/audio length to those restarts - for the one who moves getting curious and starting to experiment with what happens when he/she moves at all.

Thank you all, so much... You are faster than me.
I have strated to try the objects and effects that you suggested to me. referring to wayfaerer's question. Because it will be installed in a room, there wont be neccessarily a person on each field. Maybe only 1 person will be in interaction with the Fields to create his/her own composition or maybe 10 people will create a common work. It depends on users how to use sounds, fields and their bodies accordingly.
Thank you again for your help,
