Sample Manager 3.4

Sample Manager is the quintessential batch audio file processor for Mac OS X. Designed in Cocoa from the ground up, Sample Manager proudly takes advantage of CoreAudio, Quartz, and other solid OS X features.
Sample Manager is hands-down the most powerful and full-featured audio batch processor available today - sort files by any parameter, view detailed waveforms down to the sample, change file names, gain, fade, trim and process to your heart's content. There are over 50 process actions are available. You can chain your process actions together as Workflows, and with one click you can apply complex processes to as many audio files as you like.
Sample Manager goes beyond the call of duty by including unlimited undo, support for all known audio metadata, a hierarchical file listing with support for folders, custom groups, and even Smart Folders (which consistently search for audio files using Spotlight) and much more; all of this within an extremely well-designed and friendly interface.
