Rogue Amoeba has updated its audio editing software Fission to version 1.6.9. The minor update reduces CPU usage during playback, adds proper support for 24-bit mono files, and updates the LAME MP3 engine (which is used when pasting files into an MP3 file) to version 3.98.4. Other fixes in the new version include correcting a long hang which could sometimes occur when closing large documents, a crash related to a QuickTime file extensions bug, a glitch when fading to the end of a file, and a bug with waveform appearance at certain zoom levels.

Improve Apple Services with AirPort Base Stations
You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.
