Re: need roughness calculation results from different systems
Yes, it does... it used a diferent method in the previous versions, now I think it uses the model by pressnitzer.
I have developed a model of roughness of my own, and I have been reporting information about this in some papers. I am currently working on a camera ready paper for the international puredata convention (yes, my model was implemented in puredata) that will take place at MC GILL Canada (21st-26th Aug)! Who from the list might I meet there? I will definately talk about this!
Pressnitzer also has a model in puredata, please let me know about all the models you have encountered so far. According to Vassilakis, though, Pressnitzer's model has some failures.
Anyway, I do review most of the roughness models in my work, and so does Vassilakis on his thesis. He has a nice chapter on roughness model drawbacks, but I do have some remarks to add to his work, and I have actually been telling him about it...
Another paper that I am working on right
now also discusses the modelling, but this one is in portuguese, anyway, I will translate it to english and post it on my website too...
Please, tell me more about your research, I will be glad to participate.

vs. time plots from as many different systems as possible. I have prepared a test file and will send it to everyone willing to help me out. The file is 10sek. long, sampled at 48kHz/16bit/mono.
