Using SoundSeed Impact to pitch shift sound components instead of entire sounds
Simple pitch shift can be inflexible in some cases and can introduce undesirable artifacts. SoundSeed Impact may help avoid these problems in certain situations. The following should be taken into consideration.
Pitch shift is basically re-sampling resulting in file length duration changes. Large amounts of pitch shifting, such as one octave up results in the sound being twice as short. By using the frequency stretching transformations, SoundSeed Impact can get the same range of pitch shift without affecting the duration. An excellent example using a plastic bottle is demonstrated in the “SoundSeedSampleProject”. Feel free to download this project from our website.
Pitch shift has a global effect when applied to a sound. Using SoundSeed Impact instead of pitch shifting can be beneficial as it provides localized control over frequency. Take a gravel footstep sound for example. The SoundSeed Impact modeler allows for a specified analysis and or frequency region to be modeled, making it ideal in these cases. Once the appropriate model has been exported from the Modeler, SoundSeed Impact can synthesize and transform only the lower frequency foot impact, without affecting the gravel portion. There are many footstep examples demonstrated in the “SoundSeedSampleProject”. Feel free to download this project from our website.
