Subject | [Csnd] [semi-OT] Looking for sighted assistance: translating formulae to readable text |
Hey hey, I am currently looking at modelling engine sounds. I have found a good article, but can't read the formulae, a typical issue with PDFs. Would someone perhaps help me and translate a few equations into something like pseudo code or pseudo Tex? After some of the equations variables are explained, it would be helpful to at least have a clear-text list of the names so I can properly read the text again. Here's the article and relevant parts (I hope): Link: https://www.hindawi.com/journals/sv/2018/5209207/ Direct download of the PDF: http://downloads.hindawi.com/journals/sv/2018/5209207.pdf The following sections with the nubmered equations and figures are vital (I think): 2. (Measurements of Acoustic Characteristics of Engine Sounds) figure: 2(?) 2.1 (Spectral Characteristics of Engine Sounds) eq.: 1 3.1 (Mechanical Sound Synthesis) figure: 4 eq.: 2, 3 and 4 3.2 (Combustion Sound Synthesis) figure: 5, 6(?) eq.: 5 I'd be very grateful if someone could and would spare the time. If that balances the scales either way: the resultant Csound code will be released freely.

Here they go Eq.1 f_0 = N \cdot \frac n 2 \cdot 60 Eq. 2 p_m (t) = \sum_{k=1}^K \left(a_k \cos\left(\frac {2\pi kf_0t} {N_m}\right) + b_k \sin\left(\frac {2\pi kf_0t} {N_m}\right)\right) Eq. 3 (there are two) a_k = \frac 1 m \sum_{m=1}^M \left(\frac 1 T \int_0^T p(t + (m-1)T)\cos \frac{2\pi kt} T dt\right) and b_k = \frac 1 m \sum_{m=1}^M \left(\frac 1 T \int_0^T p(t + (m-1)T)\sin \frac{2\pi kt} T dt\right) Eq.4 (two again) A_k = \sqrt{a_k^2 + b_k^2} and \phi_k = \tan^{-1} \frac {b_k} {a_k} Eq. 5 p_c(t) = C \cdot M_f \cdot p_e(t) \cdot [p_m(t) + C_r \cdot M_f] ======================== Prof. Victor Lazzarini Maynooth University Ireland > On 25 Oct 2019, at 13:15, Jeanette C. |

Hello Victor, many, many thanks for that. I'll reread the appropriate sections again and see how far this can take me.
