An octave is an interval regarded as including eight steps , the eighth of which has the same letter name as the first note . 八度音阶是包括八个音的音程,第八个音与第一个音的音名相同。 Deep within your heart is a pure golden octave that is from the tao vying to help this creation sel...
In pure frequency-warping applications, windows can be used for both analysis and reconstruction, as is done in apparently all perceptual audio coding methods such asMPEG[16,273]. For example, the square root of the Hann window can be applied to the analysis frame as well as the final overl...
The test frequencies extended two and one-fifth octaves above and below the standard 1,000 Hz tone at equal interval fifths, and were presented for 200 msec each at constant intensity. An analysis of variance performed on the 2 by 2 nested design data indicated highly significant differences ...
To emphasize the comb structure of the supercontinuum spectrum, which results from the pulse-to-pulse coherence, the spectrum of the pulse train at the output of the chip was simulated with a resolution of 10 kHz in a narrow band interval. The spectrum is simulated by first generating a ...
An electronic musical instrument for reproducing chords or pure tones in a fixed interval scale, called Modified Eastern Music Tru-Scale Octave Transformation by the inventors, without overtone collision. The instrument includes a memory for storing and reproducing the 24 octave frequency interval system...
The inventive instrument reproduces single or multiple notes with an interval system which eliminates dissonance, and allows complete modulation in all key signatures and pure tone relationships without altering the keyboard. The invention also contemplates the use of the Modified Eastern Music Tru-Scale...
Similar simulations were performed in an interval at 2,418 and 2,580 nm, confirming the comb structure of the supercontinuum (see Supplementary Fig. 4). In the simulations, the width of the comb lines is only limited by the time window used. Interestingly, such nonlinear processes in silicon...
