Chapter 13
Using Acoustic Mirror and Wave Hammer
This chapter is designed to familiarize you with the Sound Forge® Pro Acoustic Mirror™ and Wave Hammer™ effects.
The Acoustic Mirror effect is a powerful digital signal processing tool that allows you to add environmental coloration to your existing
recordings.
The Wave Hammer effect is an audio mastering tool that features a classic compressor and volume maximizer.
What are the Acoustic Mirror effects?
The Acoustic Mirror effects represents an advance in reverb technology in that it incorporates the acoustical responses of a given
environment or venue into your audio files. You may never play Carnegie Hall, but that does not mean that your recordings can’t sound
like it. Taking this concept even further, this effect allows you to simulate the signal response of vintage musical equipment. Imagine the
money you’ll save not having to buy those paired U-47s.
The acoustic signature
Acoustic Mirror effects use the environment’s acoustic signature, or impulse response. These acoustic signatures are saved as impulse
files and given the extension .wav or .sfi. An extensive library of high-quality impulse files are included. In addition, you can collect your
own acoustic signatures and create custom impulse files.
