Internet Co Sound it! 8 Pro for Mac OS X is an audio editor primarily geared toward audio mastering applications. Though it can record tracks one at a time, providing basic editing functions for this task, it’s intended for sequencing, polishing, and exporting polished mixes.

The main window provides two views which give you an overall picture of your sound file and allows you to apply fades, cut and paste, perform edits, and monitor your left and right channels independently. Below the editor window, you’ll see transport controls, a recording-timer feature, and a jog-wheel for fast-forwarding and rewinding at different speeds.

Sound it! 8 Pro ships with many Sonnox processes including their restoration suite, Oxford EQ, reverb, limiter, and F-REX, an effect processor that allows you select a portion of the frequency spectrum/stereo spread and apply volume, panning, compression, and reverb separately to the inside and outside of the selection. A plethora of stock effects are also provided.

DSD is supported up to DSD256, making it an engine able to handle true DSD-editing and export. Linear PCM is also supported up to DXD, and you can create and export DDP files for the mastering house. Batch processing for affecting multiple tracks at once is included as well. Sound it! 8 Pro supports Audio Units plug-ins.
