Features: [1] real-valued spherical harmonics using real coefficients [2] support flexible band intervals (l=0:dl:L) including both full band SH (dl=1) and even order only SH (dl=2) [3] evaluate both function values f(theta,phi) and the derivatives of f w.r.t theta and phi. Can be used for finding peaks of spherical functions [4] implement the spherical harmonics rotation algorithm of Ivanic and Ruedenberg.

Torsion Pendulum is a lightweight VST plugin that enables you to distort the audio signal and saturate harmonics.

To do so, the plugin uses two algorithms. The first one, H.D.Shaper, creates distortion by simulating an overload from small to hard clipping, while Integrator, manipulates sound by introducing charge and discharge to the RC circuit.

This software computes synthesis of spherical harmonics models on sparse coordinates or grids (provided in a geodetic or geocentric reference system). It exploits basic parallelism using openmp directives.

A solution with MPI has not be taken into account since it cannot be so easily manageble by final users.

Christortion uses a Chebyshev polynom waveshaper to excite harmonics of the input signal.

Each harmonic can not only be adjusted surgically in dB, but also the phase of each harmonic can be inverted. With this concept you have a very wide range of distortion that can be produced..

Redline Preamp livens up any &too clean& signal with a customizable combination of even and odd harmonics, saturation, and soft clipping. Redline Preamp is a vintage console channel, a musical grunge machine, and everything in between. Unique and concise editing options allow for anything from subtle coloration to high-class grunge, from vintage emulation to fattening of digital mixes. A showcase selection of carefully constructed presets ranging from the American Vintage to the full-blown Beyond Repair is included. Highlight features include proprietary zero-latency tube modelling with detailed harmonics control, three tunable frequency bands with solo listening, and mid/side processing.

The two-step noise reduction (TSNR) technique removes the annoying reverberation effect while maintaining the benefits of the decision-directed approach. However, classic short-time noise reduction techniques, including TSNR, introduce harmonic distortion in the enhanced speech. To overcome this problem, a method called harmonic regeneration noise reduction (HRNR) is implemented in order to refine the a priori SNR used to compute a spectral gain able to preserve the speech harmonics as proposed by Plapous et al. ("Improved Signal-to-Noise Ratio Estimation for Speech Enhancement", IEEE Transactions on ASLP, Vol.

The codes in two files generate time and frequency domain representation of three basic types of amplitude modulation i>Double SideBand Amplitude Modulation (Full Carrier) (DSBAM) ii>Double SideBand Suppressed Carrier (DSBSC) iii>Single SideBand (SSB) The message signals used are combination of sinusoids of different frequency. Most authors use single tone modulation so give the initial concepts, but rarely do any one of them go beyond than. I believe the multi tone modulation representation will help in visualizing how AM will work in case of voice modulation, which certainly is composed of number of harmonics.

This model simulates three phase inverter. Sawtooth waveform has been used as the carrier. Triplen of level 1/6 of reference were injected in the reference to utilize the maximum DC link voltage. The output voltage range increases by injecting the triplen harmonics in the reference provided that two peaks of the new reference are equal to the peak of the fundamental of reference..

groups_euclid calls gp_euc and euclid to separate a set of harmonics into families or groups of related harmonics, each with its own fundamental tone. The euclid() function accepts two real numbers with uncertainty intervals, and returns their greatest common divisor (gcd), also a real number. The gp_euc() function accepts several real numbers with associated containing intervals, and returns their gcd. These two functions generalize the familiar euclidean algorithms for integers. For explanation and details please see the included Word document. Also note that visual_euclid(a,b) is an extra, visual version of euclid(), to demonstrate the rubber-band theorem.
