  We introduce a general framework for measuring acoustic properties such as
liner time-invariant (LTI) response, signal-dependent time-invariant (SDTI)
component, and random and time-varying (RTV) component simultaneously using
structured periodic test signals. The framework also enables music pieces and
other sound materials as test signals by "safeguarding" them by adding slight
deterministic "noise." Measurement using swept-sin, MLS (Maxim Length
Sequence), and their variants are special cases of the proposed framework. We
implemented interactive and real-time measuring tools based on this framework
and made them open-source. Furthermore, we applied this framework to assess
pitch extractors objectively.
