Distortion measurement on Mac
 
FuzzMeasure Pro 3

Pretty nice :nod:

I used it to do the crossover design on a little Jordan JX92 2-way design. I'm using version 3.2 and while it works well, it seems to show a bit of an overly "good" response. I'm still wrapping my head around the sweapt sine deconvolution and what the limitations are. I have a good feel for the MLS way of impulse response, and wrote my own code to do those.

If you want to see a comparison of the two, here's the last entry on my little speakers:

Flat to 60Hz? - That really appears strange...

I don't remember seeing at any time such a steep rolloff in measurement.

As I think of using Fuzzmeasure soon, I'm very interested in experiences and recommendations for comparable software for Mac.

Have fun, Hannes

If something is a good tool for the Mac, I don't mind paying a modest amount... if I must. But I hesitate to download "free demos" to check out a program because few vendors will provide the means (or explain about) the fuss in removing a demo. I think that would be good info to include in software threads like this one.

In addition to comments about removing the free demo, do FuzzMeasure3 and Wavepad work as plain real-time o'scopes and spectrum analyzers?

Removing most programs on a Mac is simply putting it in the trash. If you want to be anal there will also be a plist file in <user>/Library/preferences (ie the user Library), and sometimes a folder in the Library or the Application Support folder in the Library. There may also be similar in Library/preferences (ie the system Library).

yeah removing things on mac is a lot easier than I remember when dealing with d0oing the same in NT. planet10 has it covered there, the application, preference list (plist) which depending on how the program installs will be either in the user library or system library, or sometimes both. some will also place something in the startup folder but this is usually an alias. if it is a program that stores description files for hardware there will most times be a folder in the application support as mentioned.

if its a well written piece of software it will have an uninstall option in the installer which can often be accessed by holding down the control or option key when starting the installer (havent done that for a bit, so cant tell you for sure which from memory)

... and sometimes the many far-flung bits and pieces have names that bear no relation to the demo'd program you don't want.
... and add the to confusion and burden when you are looking to work in the "bowels" of the Mac machinery with other programs.
... and that's not so anal.

Funny, the barely limp-along MacCRO has the nicest, naturalest, Mac-like-easy set of features I've seen in my first look-sees.

funny, I never have any of these problems. maybe i'm not downloading the 'right' software.
