Mac OS X support - Run AudioDesk on the world's most advanced computer operating system.

Support for multiple MOTU CoreAudio drivers - Operate MOTU PCI and FireWire audio hardware products simultaneously with AudioDesk. For example, you can use your MOTU 828 FireWire audio interface together with your MOTU 2408mk3 PCI audio interface.

Support for Mac OS X's Audio MIDI Setup utility - Enjoy universal MIDI system management. AudioDesk shares a common studio setup with all of your Mac OS X MIDI applications for AudioDesk's MIDI Machine Control and MIDI sync features.

Multiprocessor support - AudioDesk now doubles the available processing power for plug-ins on any dual-processor Macintosh.

Collect audio data for backup - The "Save As" and "Save a Copy As" commands have a "Duplicate audio data" option that automatically collects all audio files, fades, crossfades, and PureDSP analysis files associated with the project and puts them together in a folder. It doesn't matter where the original files are: they could be scattered over several hard drives. But AudioDesk faithfully finds them and assembles them into one folder. You can then backup, transfer, compact or otherwise handle the project as a single folder with the complete assurance that all associated files are right there in the folder.

Ten levels of undo - AudioDesk remembers your last ten undo operations so you can feel free to experiment with your editing. The undo history window display the 10-step undo history at a glance and lets you jump instantly to any location in the history.

New plug-ins - All of AudioDesk's included plug-ins have been given a whole new sleek look. And you get several new plug-ins that you'll be able to put to use immediately. The new Multimode Filter provides resonant filter effects, much like a modular synthesizer. The Plate reverb provides exceptionally smooth reverb with up to a minute of reverb time. The Trim plug-in allows you to match gain, alter stereo channel imaging and provides precise metering of audio signals. Quan Jr. provides on-the-fly bit reduction for a wide array of "bit crusher" effects. A new Ring Modulator is also included.

Enhanced menu organization - Enjoy greater ease of use and faster operation. For example, all project-related commands, such as adding tracks, are now consolidated into the Project menu.

Commands System - Expanded customizable keyboard shortcuts – AudioDesk’s ‘Remote Controls’ feature has been greatly expanded into the ‘Commands’ window, which lets you assign computer keystrokes to virtually any function in AudioDesk. The Commands window allows you to completely customize your computer keyboard interaction with the software.

Automatic Conversions - AudioDesk can automatically convert audio data wherever necessary to make it conform to the current project's sample rate, sample format and tempo. These new auto-conversion features greatly streamline the process of importing audio quickly into your projects.

MP3/REX/ACID File Import - Simply drag MP3 files, REX (Recycle 2) files, or ACID files into AudioDesk to import.

Compact Project - This new command is the ultimate way to get rid of all the unused material in a project and prepare it for transfer or archiving. This command discards takes, gets rid of unused soundbites, compacts audio files, regenerates fades — all to your exact specifications and all in the right order to achieve maximum efficiency.

OMF import/export - AudioDesk supports complete multitrack session interchange with Pro Tools, including track layout, frame-accurate audio region placement and volume and pan automation data.

FireWire video output - Monitor QuickTime video via a FireWire device.

Merge Soundbites - Quickly combine several soundbites with one easy operation.

Graphic time-stretching - Grab the edge of a soundbite with the hand cursor and watch it stretch as you pull it longer or shorter.

Graphic fade handles - Edit fades graphically directly on soundbites in the Edit window. Even graphically edit multiple fades simultaneously. For example, if you needed to make all fades in a track a little longer, you can select all soundbites and then grab one fade to change them all. Fades and crossfades are preserved during editing operations, such as dragging, shifting, compacting or setting the soundbite start time. For example, if you trim the edge of a soundbite, and it has a fade on it, the fade will remain after the trim operation.

Edge-editing multiple soundbites - You can now drag the edges of multiple selected soundbites, moving them relative to one another or making them all snap to the same location.

Stationary play head – AudioDesk’s "Continuous Scrolling" preference causes the playback wiper to stay anchored to the center of the window while the data in the window scrolls behind it. You can opt to view a moving wiper as in previous versions, if you wish.

Wiper-centered zooming – AudioDesk’s playback wiper now serves as the anchor point for zooming (in and out). You can quickly zoom in to a specific location and then zoom back out, and the focus point always remains in view. This makes zooming much faster and more convenient, even during playback and recording.

Lock playback to selection - Make a selection and instantly begin looping it.

Solo exemption - Some tracks, such as aux tracks, should never be muted during soloing. The new Solo Exemption feature lets you protect tracks from being muted.

Soundbite sync points/time stamps - Instantly snap audio regions to their originally recorded time. Export/import time-stamped audio regions to/from Pro Tools and immediately restore their original positions in the track. Adjust soundbite location based on a sync point rather than the beginning or end of the region.

Audio bundles window - Create audio input, output and bus setups and reconfigure the I/O setup in your AudioDesk projects with just a few clicks.

Custom track colors - Color-code the tracks in your projects in any way you wish to clarify their grouping and organization.

Dockable tool palette - All of the tools you need are just a click away in the new dockable tool palette, which always stay attached to the edit window at any location of your choosing.

Up to 20 effects inserts per track - Today's Macs are getting more and more powerful. What does this mean? More real-time effects processing at your fingertips. AudioDesk now lets you configure up to 20 inserts per track for as much processing as you'll ever need from the many included plug-ins, or your favorite third-party plug-ins.

Measures and beats - AudioDesk now lets you specify time musically in measures and beats, so you can easily record and edit according to musical boundaries. For example, you can now set up the edit grid to snap to quarter notes or eighth notes for easy and convenient musical editing.

Global time formats - Instantly change the time format displayed throughout AudioDesk in time rulers, dialogs, and anywhere time is displayed. Choose any time format (Measures/Beats, SMPTE frames, real time or samples) and change it at any time.

Multiple plug-in windows - Open two or more plug-in windows simultaneously.
