AudioDeluxe has it for about $84. It's a one-trick pony with literally one slider that you can play with. However, gotta say - it works! I had an electric guitar part recorded through a noisy pedal board and on the quiet parts you could hear a sizzle. I appreciated the simple solution to a problem I haven't been able to overcome with other tools. I look forward to using it on some voice-over work that needs it...
