Rogue Amoeba’s Fission audio editing software gets a minor update with version 2.1.1, which offers a lone feature addition: the Batch Converter now accepts folders containing audio files as well as individual files. The release also ensures that the Save panel remembers the last saved location, corrects an issue with chapterized AACs and very large image files, and fixes an issue with the Mac App Store version where attempting to save a file would cause an error. Additionally, Fission now includes a hidden preference accessed via the Debugging window that enables the app to check for and prevent rare instances of Normalization clipping.

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.
