wvf file pc / mac incompatibility?

I used Maxi Patch AO for Windows to batch process a bunch of songs on an external firewire hard drive.

I then hooked the drive up to my Mac to run Ms Pinky. I was dissapointed to see that the 200-some files i processed on my PC weren't readible by my OSX version of Ms Pinky. Ms Pinky didn't pick up the wave forms at all...

has anyone else had this problem?

I know exactly why that is-- it turns out I very stupidly wrote the code for the waveform reading/writing such that the header information inside each .wvf file is stored as 32-bit integers. Doh! Unfortunately, the storage of 32-bit integers is broken down into four 8-bit chunks (bytes) which are written to the file in the order 1-2-3-4 on the Mac and 4-3-2-1 on the PC. This means .wvf files created on the PC won't be compatible with the Mac. I deserve to be fired for this one -- doh!

I will try to think of a solution which does not require you to re-calculate all those .wvf files... but this will have to wait for a future release. Sorry!

While I generally don't like embedding more info than necesary inside an mp3 file, in this case I think it could be really helpfull to store

the waveform calculation inside the mp3 file as an id3 tag. This way we would have less clutter (additional files) in our music collection.

I second the notion. embedded in the mp3 file would be mo better, and i guess, external files for those .wav and .aiff files.

hmmm...rats... Thanks for working on the issue though : )

to make up for it, you can make a cool ms pinky dock icon...i'm still waiting for one ; )

a small tip for those of us who don't like to see all these .wvf files around -

search for all these files and make'em hidden.. ofcourse set the system to not show hidden files.

i know it's kinda messy solution but it works
