Atomic Decomposition offers interesting properties for musical applications:
- Iterative Approximation. Control over resolution of the model
- Approximation is based directly on the signal rather than signal descriptors
- Dictionaries can be arbitrarily designed and combined (sample libraries, field-recordings, etc.)
- Model is naturally polyphonic (juxtaposition and superposition of sound grains)
- Constrained Matching Pursuit (constraint-based control over distribution of sound grains)
- Process leaves a “residual” - Multiple iterative decompositions (serial, parallel) of the same target are possible, e.g. for different orchestrations
