Spark XL for Mac

From TC Works:

With Spark you can master and edit your audio very fast and effective. It is a two-track editor, so your stereo files can be processed with VST and TDM Plug-Ins. SparkXL comes along with 12 high quality VST Plug-Ins and of course with the native DeNoiser and DeClicker for audio restauration. The can be routed serial and paralell in the powerful SparkXL FX Machine. As you have TDM support, you can use VST and TDM effects via DirectConnect at the same time. Of course SparkXL does also offer all the features known from Spark. You can create your own playlists and burn them on CD. For very detailed crossfade editing you have crossfade-editor which helps to create very precise fades. The application supports all file formats (aiff. wav. SDII, mp3), if you need to change the format - no problem with the Spark Batch Convertor. Simply import the files and change the format - during the process you can also implement VST effects. Of course all features like cut, paste, pitch shift or time stretching are no problem for Spark, too - time strecthing is even possible in realtime.
