We describe a software system for analysis, manipulation, and synthesis of low-noise sounds. The system is based on a model derived from additive synthesis, and opens new horizons for both researchers and composers. The software system consists of two separate tools: InSpect and ReSpect. InSpect performs the analysis of sampled sounds, extracting parameters and structuring them into its spectral sound model. The resulting spectral sounds can be manipulated in a very musical and intuitive way. We provide traditional operations such as filtering, time stretching, cross-synthesis, transposition while preserving formants, timbre morphing and many more. ReSpect is able to re-synthesize the audio signal from its spectral representation in real time.
