What is spectral editing?
- All other sound is simply a combination of multiple sine waves.
While a true statement, this doesn't answer the question.
- The technique of directly changing the individual sine waves within a complex wave.
- The technique of indirectly changing the individual sine waves within a complex wave.
You can change sounds by filtering, but this usually isn't referred to as spectral editing.
- The combination of many sine waves with different frequencies, amplitudes, and phases, all of which change over time.
This is the definition of spectrum, which gives sound color.
