Sometimes the dialogue in a take you want to use is much softer or louder than the dialogue in the rest of your project. Now you can use the new Voice Level option in the Lift and Stamp tools to seamlessly match dialogue volume in just a few clicks.

Soundtrack Pro instantly identifies and analyzes vocal content in both the lifted clip and the clip you stamp. It automatically adjusts the amplitude of the stamped clip to make the dialogue levels match.

Stretch and compress audio with unprecedented precision using three Apple time-stretch algorithms as well as popular third-party plug-ins (sold separately). Native support for Serato Pitch 'n Time, iZotope Radius, and SoundToys Speed lets you seamlessly switch algorithms as you work.

Use the Actions list to edit, suspend, and reorder time-stretch operations. A new option in the Time Stretch window lets you specify duration as a percentage with up to four decimal places. The window displays the number of samples added or removed as you stretch or compress audio.

Two new features make it easier—and more precise—to repair and restore damaged audio with problems such as background noise or power line hum. The improved broadband noise reduction feature uses a high-resolution noise print to reduce unwanted background audio with even more precision. In addition, the Power Line Hum feature allows you to adjust the number of harmonics you remove when repairing recordings that have picked up hum from ground loops.

The File Editor in Soundtrack Pro 3 lets you use a simple drag-and-drop interface to add, remove, and reorder channels. In the Frequency Spectrum view, you can adjust the amplitude of frequency selections as well as cut, copy, and paste them. Tighter integration with Logic Pro makes it easier for musicians to nondestructively round-trip mono or multichannel audio files when they use the File Editor in Soundtrack Pro.

New features designed for audio post make it easy to save time and work with greater precision. Fly through editing using new commands for trimming and extending clips and adding fades. Record directly into the Multitake Editor, so you don't waste precious time with separate recording setups in the Timeline. The enhanced Normalize function lets you select Peak or RMS algorithms when making level adjustments. Use the new Waveform Zoom function to closely inspect low-amplitude audio clips right in the Timeline.

Now you can speed through editing sessions using new, special-purpose commands. Work efficiently with new options for playhead scrolling, multiple concurrent snap levels for playhead and clips, user-definable nudge, and additional playback options for auditioning changes. Support for Multi-Touch trackpad gestures lets you zoom, toggle windows, and control playback without reaching for a mouse.

Previously when you wanted to evaluate an alternate take or mic placement, you had to root through the Bin or file system to find the files. Now Soundtrack Pro puts related audio files at your fingertips. Just Control-click any clip in the Timeline to call up a menu of related files. Soundtrack Pro instantly inserts any file you select while maintaining existing clip boundaries.

Soundtrack Pro 3 has a vastly reduced memory footprint and a redesigned architecture for faster performance. Automatic Audio Unit validation on launch helps ensure that your third-party plug-ins function smoothly.

Gridlines in the Timeline intelligently adjust to your zoom level, so you always maintain a clear view of frame boundaries and clip locations.

Soundtrack Pro now notifies you when you attempt to export AIFF, WAV, and SDII files that are larger than the 4GB maximum allowed by these three audio file specifications.

Soundtrack Pro now reads iXML metadata, which is used in audio field recording to capture details such as project name, scene number, take number, and notes. You can view the iXML metadata in the Bin, in the Details pane in the Multitrack Editor, and in the Project pane in the standalone File Editor. In addition, Soundtrack Pro uses iXML tags behind the scenes to help identify related files and display channel information in the "Replace with Related File" pop-up menu.

Easily shift clips across the Timeline by spotting to the playhead location or timecode value.

Instantly access commonly used track controls using new menu items and keyboard shortcuts. Just type R for Record Arm, T for Mute, and Y for Solo.

It's now especially easy to create and modify cycle regions. Create a cycle region by dragging in the lower ruler. To remove the region, simply double-click the lower ruler or drag the cycle region to zero duration. Deep integration with Euphonix control surfaces

With new support for the EuCon protocol, Soundtrack Pro lets you experience tactile control through an attached Euphonix control surface, from fully equipped Pro Series consoles to portable Artist Series units (sold separately). Choose the Euphonix MC Mix for desktop mixing or select the MC Control, which now features a high-resolution touchscreen interface designed specifically for surround panning in Soundtrack Pro 3.

DC offset can significantly impair audio quality through reduced headroom and related artifacts. Soundtrack Pro now detects and repairs audio with variable DC offset as well as fixed DC offset.

New Quick Look support lets you instantly audition Soundtrack Pro Audio File Project (STAP) files from anywhere in the Finder. Just tap the Space bar to play the STAP file without opening Soundtrack Pro.
