Since you don't want to collect audio samples the best I could suggest is to have some filtering of the compressed spectrum. for instance \underbrace{\int_{-\infty}^{\infty} \left( \sum_{k=1}^{\infty} u_k \cdot c(h(\omega/\omega_1) X\left( \frac{k\cdot \omega}{\omega_1}\right) \right) d\omega}_{\textrm{Harmonics}} + \underbrace{\int_{-\infty}^{\infty} \...
