Working with (original) digital samples and sounds is a snap with Sound Forge. Once a sound is transferred to the program, it's shown as a spectrogram (a graph of complex sound waves). I absolutely love the "Process" and "Effects" tools and commands. You can choose from a wide variety of ways to distort music and sounds. Here's what I've been using a lot, lately:
Reverse: Located under "Process" samples are played backwards!
Time Stretch: Also under "Process" sound can be lengthened so that everything sound like it's in slow- motion.
Pitch Bend: With this tool any highlighted region can be distorted by moving specific points on a grid.
Delay: This tools helps to create echo or resonance effects. I particularly like the "Echo Chamber" and "Dreamscape"
Flange/Wah-wah: Create sounds reminiscent of an airplane, or go "retro" with the "Wah" used in the 1970s.
Where did I find the Sound Forge, you ask? Well, it comes packaged with a turntable/record player. In fact, this program allows people to make recordings and restorations on analog vinyl, The only problems are that you need a recording studio and blank records to do this.
