Sound it! 8 Pro
Sound It! 8 Pro (which I’ll call SI8P from now on) has a solid set of basic audio editing features. These include typical file editing options, audio format conversion, a broad array of bundled plug-ins (spanning EQ, dynamics, spatial effects, modulation and mastering treatments), basic automation, useful metering tools, batch processing, well-featured CD creation, the ability to create Acid files and, as mentioned earlier, support for handling DSD and high-resolution PCM (DXD) files. Exactly what you can do with these more specialist audio formats depends upon the specification of whatever audio interface you might have available but, even so, DSD support is a rarity amongst the mainstream audio editors.
