| 描述： | This sound uses S: harmonica1.wav by swapnil_gt | License: Creative Commons 0 This sound (like an organ) transforms the specified just above. It was done for the 8A Peer Assessment of the ASPMA Coursera course. Following is the explanation I gave of how I got the uploaded sound using the HPS model from the smstools software: The analysis parameters are window'blackman', M1201, N2048, t80, minSineDur0.1, nH40, minf0450, maxf0850, f0et5, harmDevSlope0.001, stocf0.1.The original sound consists of the notes C5, D5, E5, G5. I scale frequencies in order to get enharmonic differents between the notes so I would have C5 and B5 sharp, first, and E5 and F5 flat later. So:Frequency scaling factors: I scale time factors in order to get that each note last approximately one second, and compressing intermediate spaces between notes.So:Time scaling factors: After checking different combinations with factors 1, 0.9, 0.8, 1.1 and others, I decided strecth all frequencies by 0.9 since I get the best result, at least for my taste. So:Frequency stretching factors: Because of the same reason, I prefer Timbre preservation 1. |
