In using the ListWaveform and Show functions in the Miscellaneous`Audio` standard package of Mathematica, anytime I call Show with more than one Sound object argument Mathematica crashes with the system error shown below. This also happens if I use the built-in Play function to generate the sound object, so the crash doesn't depend on using the Miscellaneous`Audio` package. Also, Show works fine when given multiple Graphics object arguments. I am running Mathematica 5.2 under MacOS 10.4.6 on a 1.6 GHz PowerMac G5 that has 1.25 GB of RAM and about 130 GB of free hard disk space. This crash also occurs on a colleague's PowerMac G4 running the same version of MacOS but another colleague tried this same code (taken right from the Help examples for Miscellaneous`Audio`) under Windows XP and it ran without problems. It seems to be a general problem that Mathematica 5.2 running under MacOS experiences a crash when calling Show with multiple Sound arguments. Is this a "bug" or a "feature"? < Miscellaneous`Audio` partialList = {{1,1},{1.1,0.1},{1.2,0.9},{1.3,0.2}, {1.4,0.8},{1.5,0.3},{1.6,0.7}, {1.7,0.4},{1.8,0.6},{1.9,0.5}} seq = Table[ListWaveform[partialList, 440 2^(x/12), 0.2], {x,0,9}] Show[seq] Here's the text that appears in the box after Mathematica crashes: The application Mathematica quit unexpectedly. 2006-05-10 14:06:28 -0400 EXC_BAD_ACCESS (0x0001) KERN_INVALID_ADDRESS (0x0001) at 0x06f19ff0 Thread 0 Crashed: 0 __memcpy + 1120 (cpu_capabilities.h:189) 1 0x1000 + 822264 2 0x1000 + 81676 3 0x1000 + 830144 4 0x1000 + 826776 5 0x1000 + 590624 6 0x1000 + 564508 7 0x1000 + 562328 8 0x1000 + 554788 9 0x1000 + 31952 -- Mark Normand UMass.
