Blowing in a bottle: getting the frequencies

Following up the conversion from video to sound file , let's go further in our guess at how much Rico Loop drinks. We are going to look at the nature of the sounds produced at each step of Rico Loop's video, using the signal's power spectrum. With Audacity , we get a power spectrum this way: select a portion of the sound in the menu Analyze , choose Plot Spectrum... To illustrate this post, I show, at the left of the power spectrum, the spectrogram with the sound snippet selected. First interesting pitch, at 0:19: We see that the pitch results from a very isolated peak in the spectrum. Here, the frequency is 512 Hz.   At 0:23, we read 417 Hz.     The three following peaks are: 350 Hz at 0:40, 290 Hz at 0:53, and 235 Hz at 1:02. Try you own analysis, for instance with Audacity, or with another sound analysis tool. Now, you should be able to find out how much Rico Loops drinks at each step.

Electroclarinet 5 - score

Looking for the studio album? Visit Electroclarinet 5 is a composition for A clarinet & live electronics, written in homage to Igor Stravinsky . I completed the clarinet part on May 11th, 2013. The score is built around four (circled) motives directly inspired by Stravinsky's works: the Three Pieces for Clarinet solo and the Piano-Rag-Music . Electroclarinet 5: the clarinet part (click to enlarge) The performer plays around the score, following paths of her/his choice. Routes from one basic motif to another are either written (circle), or to be improvised (on black lines). When the clarinetist adventures outside the box (black arrows), s/he starts again from any place in the score (including from another place outside the box). The live electronics part uses advanced playing mode recognition to adapt sound processing to the clarinetist’s improvisation and interpretation. More on that later!
