Time Scale Modification

Figure 7.9: Time Scaling for Sines + Noise + Transients Models (from [132]).

• In sines+noise models, transients are ``smeared'' over time
• In sines+noise+transients models, they are only time-shifted
• Missed transients can cause artifacts in S+N+T models
• Need to consider carefully what should be defined as a transient
• Hybrid schemes possible (transients stretch some)

See §10.4.11 for more about Levine's sines+noise+transient model, and of course Levine's thesis (available online) [132].
