Hallo everyone, I'm new to signal processing and spectral analysis, and I want to determine freqency of one single sin wave in white noise with MUSIC algorithm and bring it on uC and FPGA. e.g I decide to use the SVD approach(singular value decomposition) and begin with sample data length N=256. Let p = 100 then i have a data matrix of p x (N-p) = 100 x 156. (U,S,V)=SVD(A) on a matrix of th...

HI NG! I'm not shure whether this is the appropriate group for my question so please apologise if I'm wrong. I'm searching a free program (preferrably on linux) which I could use to make electronic music with, typically drum&bass. Ideally, I'd like to compose some bass rythm on 4 measures or so and make it loop, and then add some sound samples on top of it. I don't have the samples but the ...

Hello! I'm a soon (hopefully) graduating music teacher who's quite lost in the general field of signal processing. I'm trying to write my graduating work about intonation in amateur choir music.

In order to reliably answer that question I need to be able t...

I am researching the capability of various wireless speech codecs in handling DTMF digits. Since these codecs are typically rather low rate, one would expect that their ability to reliably transmit pure tones, music and/or multitone digits would be compromised. I see in the SMV codec specification that they specifically have implemented a method of supporting both music and digits; what abo...

hello all, I am designing an application where I have an MP3 (music) decoder along with a speech encoder (not music quality). The encoder should preferably be able to store a file in audio format on a SD-card. I am looking to find a single chip / chipset with minimal number of components for my design. I did find some encoder/decoder chips from a few manufacturers (Micronas MAS3587F, VL...

Hi, I am looking for a free code/library preferably under linux for speech pitch tracking. The best match I have found so far is "aubio" library. However, it seems to be mainly for music applications. Does it make a difference to usea pitch tracker for music vs speech or they are generally the same? If any one is familiar with aubio I would appreciate if you let me know whether it works fo...

Problems estimating frequencies from the Root-MUSIC algorithm. Starting from the noise & signal subspaces, I form the polynomies from the noise subspace. Then I choose the x roots closest to the unit circle (roots whose absolute values are the closest to the unit circle) (being x the number of signal eigenvectors) Having the complexes roots I can calculate the DoA (direction of arrival) My ...

As we know, ESPRIT is a Direction-of-Arrival finding method which can provide us a close-form solution, i.e. the source bearing is calculated directly by this method. However, for MUSIC and MVDR methods, they have no close-form solution. The source bearing is determined by searching for the peaks in the spatial spectrum plot. It is difficult especially when two or more sources are present....
