Can you elaborate? I have no idea what this software does. OK. This software analyze mathematically the sound files. For example: spec= trum, harmonics, formants, pitch, similitude between sounds, periodicity, e= tc... Sound files have a high quantity of information. Animal sounds can ha= ve frequencies between 20 and 20000 Hz or even more if you are studying spe= cies that emit ultrasounds such as cetaceans. A simple file of 5 minutes of= a dolphin that a range between 20 and 150000 Hz that vary continuously. A = simple spectra of this file in a normal computer can require 15 minutes in = the calculus. The first problem for me is determining the software that I n= eed. Audacity is quite good editing but is limited in the mathematical info= rmation that analyze. R have sound libraries that are very useful but curio= usly can not with long sound files. Even I had tested by SSH a computer in = the Physics Department with R under a Debian system, with 32 processors, 64= GB and the cost in computing time is very high. Probably this is due to th= e design in the construction of the software that can not use the parallel = processing of information. Praat is the best election for the mathematical = analysis of very long audio files, almost in my case. The secondary questio= n is the operating system. As I only can use Praat in my laptop I need the = maximum performance. I had observed that FreeBSD respond very good to high = consume rates. Linux is slower. Probably this difference is minor for norma= l work but empirically I observe important differences. With Debian in many= occasions my laptop is completely blocked. When I use FreeBSD I can prepar= e the analysis of a sound file and continue with the rest of activities (ma= il, web, text processor, etc...). My laptop never is blocked with FreeBSD a= nd the time of analysis is minor. This is my experience but I have not benc= hmarks or detailed explanations.
