Rayverb by Prosoniq is an inverse retraycing reverb. Raytracing is a technique used in the generation of computer generated imagery (CGI) to create reflective surfaces, so Rayverb allows you to change the position of your sound source within the room, change the material of the walls, apply material from a different ambience or even alter the proportions of the room, all in realtime.

Rayverb will be a VST plugin, but Prosoniq has just posted a standalone version for Mac OS 9 and OS X for download (3.3 Mb).

After the LynxTwo and L22 digital audio interfaces drivers posted in November, Lynx Technology has announced that a Mac OS X-compatible driver is now available for its AES16 audio interface. All 192 kHz interfaces by Lynx are compatible with the 3.3 v. PCI-X interface found on the Mac G5 models.

Synthetic Instruments (SI-KTK) is a CD-ROM library with 43 waveform sets and more then 250 individual synthesizer instruments. SI-KTK will work in Kontakt version 1.2 and up. SI-KTK's instruments are true subtractive synthesizer programs, taking advantage of Kontakt's synthesizer engine, filters and modulation capabilities. Carefully prepared and unfiltered audio spectrums has been programmed and sampled, using an Analogue Systems 5-VCO modular and a Waldorf Microwave XT. The instruments were made by combining the audio data with parameter and filter tweaking - inside Kontakt.

Garritan has annouced that Garritan Personal Orchestra is now shipping. Garritan Personal Orchestra is an impressive orchestral sample library, and ships with Native Instrument KONTAKT Player and Ambience Reverb. GPO works with notation programs and will run on Mac OS either as a standalone program or as a plug-in (supporting VST, RTAS, and OS X AudioUnits).

Garritan Personal Orchestra costs 249 dollars.

I thought it was deja vu at first but there is in fact another AudioFinder upgrade in just a matter of days. Our friends at Iced Audio just don't sleep! 3.1 adds a waveform overview for convenience, so you can see what's going on in your audio files. This app is ideal for running alongside a production session or, better yet, routed to your headphones during a live set with software like Ableton Live.
