A moment-enhanced spectrogram is an iteratively improved spectrogram whose useful low-order time frequency moments (e.g. spectral energy, group delay, instantaneous power or envelope power, and instantaneous frequency) are identical to those of commonly used time-frequency distributions, (e.g. Wigner-Ville), without having any negative values or interference terms. This paper presents a detailed intercomparison of moment-enhanced spectrograms, Wigner-Ville distributions, and spectrograms for a...
As many acoustic signal processing methods, for example for source separation or noise canceling, operate in the magnitude spectrogram domain, the problem of reconstructing a perceptually good sounding signal from a modified magnitude spectrogram, and more generally to understand what makes a spectrogram consistent, is very important. In this article, we derive the constraints which a set of complex numbers must verify to be a consistent STFT spectrogram, i.e. to be the STFT spectrogram of a real signal, and describe how they lead to an objective function measuring the consistency of a set of complex numbers as a spectrogram. We then present a flexible phase reconstruction algorithm based on a local approximation of the consistency constraints, explain its relation with phase-coherence conditions devised as necessary for a good perceptual sound quality, and derive a real-time time scale modification algorithm based on sliding-block analysis. Finally, we show how inconsistency can be used to ...

The bilabial trill is uncommon. The coronal trill is most frequently alveolar [r͇], but dental and postalveolar articulations [r̪] and [r̠] also occur. An alleged retroflex trill found in Toda has been transcribed [ɽ] (that is, the same as the retroflex flap), but might be less ambiguously written [ɽ͡r], as only the onset is retroflex, with the actual trill being alveolar. The epiglottal trills are identified by the IPA as fricatives, with the trilling assumed to be allophonic.[1] However, analyzing the sounds as trills may be more economical.[2] There are also so-called strident vowels which are accompanied by epiglottal trill.. The cells in the IPA chart for the velar, (upper) pharyngeal, and glottal places of articulation are shaded as impossible. (The glottis quite readily vibrates, but this occurs as the phonation of vowels and consonants, not as a consonant of its own.) According to Esling (2010),[3] palatal trills are also implausible. The upper pharyngeal tract cannot reliably ...

Prof. Erik Zornik [biology 2012-] has been awarded a $444,000 grant from the National Institutes of Health to support his research on mechanisms in the brain that generate rhythmic behavior-with the goal of finding new treatments for neurological disorders.. Prof. Zornik is interested in how behavioral variation is encoded in neural circuits. His research investigates a hindbrain central pattern generator (CPG) that generates the courtship vocal behaviors of African clawed frogs, Xenopus laevis.. "Adults of this species exhibit a rich vocal repertoire of at least seven call types that range from rhythmically simple to temporally complex," Zornik explains. "Xenopus vocalizations are sexually differentiated; males and females produce calls with distinct temporal characteristics that are regulated by steroid hormones during development and in adulthood. This makes their vocal behaviors an ideal subject for understanding the neural basis of behavior and behavioral plasticity." ...
Type 6 red crossbills recorded near the entrance kiosk at Rose Canyon. Seen well with binoculars and photographed while feeding. Very large beaks. There were two birds (one male and one female) that had just finished feeding on cones atop a tree (species unknown). When they took flight they called as they flew south. Flight call type identified by comparing audio spectrograms with figures in Irwin (2010) and Young (2012). The sounds of the wingbeats are superimposed on the flight calls in the latter half of the recording.. Flight calls confirmed as type 6 by Matt Young at the Cornell Lab of Ornithology.. Equipment: Olympus LS-10, Telinga 22 inch dish, and a Sennheiser ME62 microphone.. Modifications to the file: cropped.. The sounds of a digital camera photographing the birds and loud wind are also audible.. bird-seen:yes. playback-used:no. ...

Participants responded enthusiastically to the spectrograms, especially the second question where many talked about their relationships (or lack thereof) with their fathers. Sensing energy around these stories, I faced a crucial decision about how to spend the final hour. I decided to give an opportunity for participants to tell stories and play them back for each other. It proved to be a leap that exposed telling vulnerabilities and insights about men in Playback Theatre.. To tell and play the stories, I invited stories from men using a circular format in which one person told his story, three men played across the circle and one accompanied as a musician. The roles then rotated counter-clockwise. The form I suggested was an adaptation of Fluid Sculptures, focusing on the "emotional essence" of the story. Actors could take different roles in the story (with at least one person playing the tellers character). The training in the form proved to be a complicating factor. The first story told was ...
Linguistics, like other scientific disciplines, is centrally reliant upon visual images for the elicitation, analysis and presentation of data. It is difficult to imagine how linguistics could have developed, and how it could be done today, without visual representations such as syntactic trees, psychoperceptual models, vocal tract diagrams, dialect maps, or spectrograms. Complex multidimensional data can be condensed into forms that can be easily and immediately grasped in a way that would be considerably more taxing, even impossible, through textual means. Transforming our numerical results into graphical formats, according to Cleveland (1993: 1), provides a front line of attack, revealing intricate structure in data that cannot be absorbed in any other way. We discover unimagined effects, and we challenge imagined ones. Or, as Keith Johnson succinctly puts it, Nothing beats a picture (2008: 6).. So embedded are the ways we visualize linguistic data and linguistic phenomena in our research ...
Ok, so we get past the ads and we buy the product. Most of the stuff is utter and total crap. Remember the days you could buy a tea kettle and it would last long enough to leave to your kids? Im not even talking high technology here, just a kettle. How difficult is it to make a kettle that holds water, looks nice, and whistles when the water boils so you dont burn your house down (or at the very least dont melt the kettle all over your stove top, been there done that). About six months ago I stupidly didnt put the whistle on my kettle… you get the idea. I have bought three kettles since then. The first one was so cheap it didnt whistle even though it was supposed to, the next was expensive but too small, and the third now reposes on my stove. Its black, it has a whistle, its made by Kitchen Aid. It sucks. Really it does. The whistle is so faint its more like a slow leak and there is physically no way to pour boiling water out of it without sloshing scalding water all over the place ...

Next, the pull request asks if: instead of the frequency being on a linear scale, is it possible to make it a log scale? Looking at the spectra.spectrogram class in sunpy, I see that the linear frequency scale took some work to implement. Simply implementing a logy keyword would be confusing with the linear keyword already in place. So, I am trying to implement the axes.set_yscale(log) after the linear scale is established. Perhaps this could be changed just before plotting for an easy addition to the class. Otherwise, I plan to implement a log frequency axis in a similar way to the linear frequency axis ...

as in perro, for example is an alveolar trill. Trills are very different from flaps. Whereas with a flap (or tap), a specific gesture is used to strike the active articulator against the passive one, in the case of a trill the articulator is held in place, where the airstream causes it to vibrate. Usually a trill vibrates for 2-3 periods, but may be up to 5, or even more if geminate. However, trills may also be produced with only a single period. Although this might seem like a flap, the articulation is different; trills will vary in the number of periods, but flaps do not. Trill consonants included in the International Phonetic Alphabet: [r] - alveolar trill [ʙ] - bilabial trill [ʀ] - uvular trill [ʜ] - voiceless epiglottal trill [ʢ] - voiced epiglottal trill In addition, [ʩ] - velopharyngeal fricative found in disordered speech sometimes involves trilling of the velopharyngeal port, producing a snort. The bilabial trill is uncommon. The coronal trill is most frequently alveolar [r͇], ...
Speech sounds, as heard by listeners, contain phonetic, personal, and transmission information. The differences between the formant frequencies of vowels spoken by men, women, and children show a fairly uniform tendency in several studies and languages, and they are regarded as personal quality differences. The differences between the sexes are mainly due to the descent of the larynx in males during puberty. The observed tendency in female/male formant frequency ratios is reproduced in a calculation taking into account the physiological consequences of larynx descent and assuming that the vowel specific neural commands to the articulators remain unchanged. The perception of phonetic quality is seen as a process of tonotopic gestalt recognition. The tonality (=critical-band rate) distances between the formants in phonetically identical vowels are claimed and shown to be invariant as long as they are smaller than 6 Bark. The absolute position of the formants allows personal variation. The tonality ...

In order to verify that the various conditions were recorded properly, several quantities such as spectrum, short-time spectrum and sound pressure level have been extracted from the audio signals. This was possible, because the digital amplitudes of the recorded signals were calibrated to a reference sound pressure level of 100 dB(SPL) which corresponds to an amplitude of 0 dBFS. Moreover, the extracted quantities facilitate conclusions with respect to dependencies between the physical properties of the sound sources and the results of the psychoacoustic experiments. The properties resp. the extracted quantities of the recordings of the passenger car and the motorcycle are compared in the following: Spectrograms: As an example, the spectrograms for the passenger car and the motorcycle for condition v = 100 kph and d = 4 m are shown in Figure 2a and Figure 2b. Here, the Doppler shift - due to the translational movement of the vehicles - can easily be observed. Moreover, the differences in the ...
The mechanism of sound production in the collared dove Streptopelia decaocto was studied to test the validity of the whistle model and to analyze the role of vocal tract resonances. In this study, the vocalizations of six male adult doves were recorded both in normal air and in a mixture of 80 % helium and 20 % oxygen (heliox). Depending on the way in which the syrinx operates, the spectral structure of the vocalizations is expected to show specific changes in heliox. The effects of heliox differed substantially depending on the type of vocal element. Except for a significant decrease in amplitude, unmodulated elements, i.e. elements with a constant frequency, were relatively unaffected by heliox. In contrast, modulated elements, i.e. elements with an abrupt increase in frequency, showed a gradual increase in frequency with increasing helium concentration. This specific increase in frequency stopped when the modulation frequency was 1.5 times the base frequency, even when the helium ...
Would anyone notice if a referees whistle transmitted a secret data burst?. I do really follow the game. But every time the pea whistle sounds to start the jam I cant help but think of the possibility of embedding data in the frequency fluctuation. Im sure its alternating between two distinct frequencies. Is it really that binary? How random is the fluctuation? Could it be synthesized to contain data, and could that be read back?. I found a staggeringly detailed Wikipedia article about the physics of whistles - but not a single word there about the effects of adding a pea inside, which is obviously the cause of the frequency modulation.. To investigate this I bought a metallic pea whistle, the Acme Thunderer 60.5, pictured here. Recording its sound wasnt straightforward as the laptop microphone couldnt record the sound without clipping. The sound is incredibly loud indeed - I borrowed a sound pressure meter and it showed a peak level of 106.3 dB(A) at a distance of 70 cm, which translates ...
The theory of Shannon entropy was applied to the Choi-Williams time-frequency distribution (CWD) of time series in order to extract entropy information in both time and frequency domains. In this way, four novel indexes were defined: (1) partial instantaneous entropy, calculated as the entropy of the CWD with respect to time by using the probability mass function at each time instant taken independently; (2) partial spectral information entropy, calculated as the entropy of the CWD with respect to frequency by using the probability mass function of each frequency value taken independently; (3) complete instantaneous entropy, calculated as the entropy of the CWD with respect to time by using the probability mass function of the entire CWD; (4) complete spectral information entropy, calculated as the entropy of the CWD with respect to frequency by using the probability mass function of the entire CWD. These indexes were tested on synthetic time series with different behavior (periodic, chaotic and random)

In human pre-mRNA splicing, infrequent errors occur resulting in erroneous splice products as shown in a genome-wide approach. One characteristic subgroup consists of products lacking one cassette exon. The noise in the splicing process, represented by those misspliced products, can be increased by cold shock treatment or by inhibiting the nonsense mediated decay. Here, we investigated whether the splicing noise frequency increases with age in vivo in peripheral bloods cells or in vitro in cultured and aged fibroblasts from healthy donors. Splicing noise frequency was measured for four erroneously skipped NF1 exons and one exon of RABAC1, AATF and PCGF2 by RT-qPCR. Measurements were validated in cultured fibroblasts treated with cold shock or puromycin. Intragenic but not interpersonal differences were detected in splicing noise frequencies in vivo in peripheral blood cells of 11 healthy donors (15 y-85 y) and in in vitro senescent fibroblasts from three further donors. No correlation to the age of the
Context. Sunspot oscillations are one of the most frequently studied wave phenomena in the solar atmosphere. Understanding the basic physical processes responsible for sunspot oscillations requires detailed information about their fine structure. Aims. We aim to reveal the relationship between the fine horizontal and vertical structure, time evolution, and the fine spectral structure of oscillations in a sunspot umbra. Methods. The high spatial and time resolution data obtained with SDO/AIA for the sunspot in active region NOAA 11131 on 08 December 2010 were analysed with the time-distance plot technique and the pixelised wavelet filtering method. Different levels of the sunspot atmosphere were studied from the temperature minimum to the corona. Results. Oscillations in the 3 min band dominate in the umbra. The integrated spectrum of umbral oscillations contains distinct narrowband peaks at 1.9 min, 2.3 min, and 2.8 min. The power significantly varies in time, forming distinct 12?20 min ...
Many factors could influence repertoire size and function. Here, we provide a review of the descriptions of vocal repertoires of New World jays and a unifying terminology for function of their vocalizations. We summarized 19 different functional types of vocal behaviour shared by at least two species, for review purposes. Comparing the 14 studied species, we also classified vocalizations into four major classes defined a priori: Social Integration, Conflict Resolution, Predator-related, and Breeding. Cooperative breeding, as well as group size, are related not only to repertoire size, but to how species allocate their vocalizations into functional classes. We discuss the tendencies of Conflict Resolution and Social Integration and the possibility of the existence and implications of a trade-off between those functional classes. We identified gaps in the current knowledge on vocalizations of the studied species, and emphasize the importance of empiric evidence of vocalization function in the New
TY - JOUR. T1 - Constrained expectation-maximization algorithm for stochastic inertial error modeling. T2 - Study of feasibility. AU - Stebler, Yannick. AU - Guerrier, Stéphane. AU - Skaloud, Jan. AU - Victoria-Feser, Maria Pia. PY - 2011/8. Y1 - 2011/8. N2 - Stochastic modeling is a challenging task for low-cost sensors whose errors can have complex spectral structures. This makes the tuning process of the INS/GNSS Kalman filter often sensitive and difficult. For example, first-order Gauss-Markov processes are very often used in inertial sensor models. But the estimation of their parameters is a non-trivial task if the error structure is mixed with other types of noises. Such an estimation is often attempted by computing and analyzing Allan variance plots. This contribution demonstrates solving situations when the estimation of error parameters by graphical interpretation is rather difficult. The novel strategy performs direct estimation of these parameters by means of the ...
Ooh, surprise! Those spontaneous sounds we make to express everything from elation (woohoo) to embarrassment (oops) say a lot more about what were feeling than previously understood, according to new research from the University of California, Berkeley.. Proving that a sigh is not just a sigh [a reference to the song, As Time Goes By? The lyric is "a kiss is still a kiss, a sigh is just a sigh …"], UC Berkeley scientists conducted a statistical analysis of listener responses to more than 2,000 nonverbal exclamations known as "vocal bursts" and found they convey at least 24 kinds of emotion. Previous studies of vocal bursts set the number of recognizable emotions closer to 13.. The results, recently published online in the American Psychologist journal, are demonstrated in vivid sound and color on the first-ever interactive audio map of nonverbal vocal communication.. "This study is the most extensive demonstration of our rich emotional vocal repertoire, involving brief signals of upwards of ...
In addition to the place and manner of articulation, we can say that a consonant is voiced or voiceless. Put your fingers on your Adams apple for a moment and say something. Can you feel the vibrations? Thats because your vocal chords are being used. If a sound is voiced, it is because the vocal chords are used. But we dont always used our vocal chords to make consonant sounds - in fact, almost half of the consonant phonemes in English are voiceless, meaning that there is no movement made in our larynx. You may come across some classifications which refer to aspirated and unaspirated sounds rather than voiced and voiceless. This can be a little confusing, as generally voiced sounds are unaspitated and voiceless ones are aspirated. Aspiration refers to the airflow that is produced, and theres an easy test we can do to find out if a phoneme is aspirated or not. Put your hand, or even better, a sheet of paper, in front of your mouth. Now make the sound /b/. Does it move? Now make the sound /p/. ...
Really weird. I was home alone once and heard a whistle whistling "How lovely are your branches" part of that one Christmas song. I was home alone at that time. I heard it again while i was in bed about a week or 2 later. I also hear random whistling just casual long straight standard whistle. I haven't heard it in a while but there was some weird experiences with ghost in this house before. But we did get a priest to bless our house WAYYY before the whistling happened. I'm 15 but 14 at the time it always happened. Don't know if that helps or anything but yeah...Is it a ghost? No one has really died in my family but a close friend did but none of them whistled at all so it can't be a someone I know if it is a ghost. And no it is not "Tittusm" or whatever that thing is where you hear whistling or ringing in your ear.
