MacCRO X is an oscilloscope and spectrum analyser currently under development for Mac OS X. When complete, it will support analysis of data captured from sound input devices, or stored in recorded audio files.
MacCRO was originally developed for classic Mac OS, but that version is no longer distributed or supported. This version will (eventually) be better than the original.
MacCRO X is written in Objective-C using Apple's Cocoa framework. I have also had offers of help to develop a Linux version using the GNUstep libraries. If you wish to assist in some way, please contact me.
An alpha release of MacCRO X (for Mac OS X 10.2 only) is now available. Please note that this is only a testing release. There may be bugs, and there are a few features still missing which will be implemented in the near future. However, if you think you might find MacCRO useful, please download it and try it out. If you find any bugs, you can report them using the bug tracker on MacCRO's SourceForge page.
