Opening old SoundEdit 16 files...

Is SoundEdit properly installed in the Classic environment? Some programs install special features in the System Folder and it is possible that these didn't get installed in the Classic environment.

Classic isn't the same as running OS9. It is an emulator and OSX is really still in control. Some programs require close interaction with the System and when you run Classic it isn't really Classic's multimedia programs in charge of that end of thing but OSX's. Multimedia programs are typical in this requirement and many OS9 AV programs don't work in Classic since they have to interact closely with a radically different operating system.

SoundEdit files seem to be pretty proprietary. [SoundConverter|http://www.versiontracker.com/dyn/moreinfo/macosx/18047] may be able to convert them, though the utility seems to receive pretty lukewarm reviews.

ResEdit ?, or even iTunes ? I've used both for some of my old SoundEdit files. I also used SoundConverter to get older sounds into the System 7 sound format which is easily imported into iTunes.

There's also SoundLeech (from System 6 days) for those really stubborn sounds that just won't work. Very little chance of it working under Classic tho', but if the SoundEdit documents are important, you can go down a Mac+ or Mac II emulation route to run some of these.

Edit:
This has come up before more than once in the discussions, maybe we gave the same advice then ...

Hi, Navarro -

Apple KBase Article #HT1835 - Mac OS 8, 9: Compatibility With Macs lists most of the machines which can use OS 8.0 through 8.5.
