hey eske,<div><br></div><div>you can do a lot with Tristan Jehan's analyzer~ object - which is based in part on Miller Puckette's fiddle~ object</div><div><br></div><div>it is not stereo, and it won't find a "sound-object" for you - but if you spend some time analysing a field recording and isolate the unique features of a sound - e.g. by looking beyond frequency filters to spectral features like noisiness, brightness and envelope features, you could then run two analyzer~ objects - one each for L & R - and then try to filter out whatever is not matching your target parameters and then measure the loudness in each channel. this is just a guess, and I'm sure there's much more knowledgeable folks who actually know what they're talking about.</div>
<div><br></div><div>You may also want to look at IRCAM's gesture follower example patches that come as part of the free FTM package. Once example shows how to recognise voices using a Hidden Markov Model trained on MFCC's extracted from the sound samples. You could do the same thing to have a realtime system that can recognise the presence of a particular sound object. There's probably a fair bit of work to do in selecting audio features and training such a system.</div>
<div><br></div><div>So, I reckon it's possible, but we're probably still waiting for someone to right [cocktailpartyeffect~] :-)</div><div><br></div><div>regards,</div><div><br></div><div>Mark</div><div><br><br><div class="gmail_quote">

hi microsounders, <div><br></div><div>i'm interested in finding realtime audio analysis tools for realtime soundscape/soundwalk processing with max msp. </div><div><br></div><div>how can we make maxmsp know where in a stereo field a "soundobject" comes from? how can we separate one "sound-object" from</div>
<div>the noise, without it being to rude(simple highpass, lowpass filtering)?</div><div><br></div><div>is there a [cocktailpartyeffect~] object or something alike out there...?</div><div><br></div><div>realtime seems to be the key issue (in my mind)?</div>
<div><br></div><div>any ideas, links, etc are very welcome!</div><div><br></div><div>cheers, </div><div>eske</div><div><br></div><div><a href="http://worgw.org" target="_blank">worgw.org</a></div>
