Like several others over the years in this group, I'm trying to write code that can be used as a music tuner. Specifically, I'm trying to emulate programs like SmartMusic and Karaoke Revolution. The former is a program that accompanies a music performance and can vary its accompaniment based on what the human performer is playing. The latter is a PlayStation 2 game that scores the player o...

This is a followup to an article I posted a month or so back on music transcription. I've provided enough detail here, along with a key web link, to make it possible for any of you interested enough and equipped with the right analysis software to try out the process I'm about the lay out for yourself. As I mentioned there, I've decided to adopt an approach to doing dictionary-based transc...

hi everyone, I have posted many queries regarding implementation of MUSIC algorithm in MATLAB. Now I have written a program that estimates the DOA using music algorithm. There are some queries and doubts about the results I got from the output which I would like to share. Let N be the no of sensors and M be the number of signals incident on the sensors. When I do the SVD of the auto correlatio...

Hi guys, I am trying to implement the MUSIC algorithm and the more specialized case of Pisarenko and I am not sure if my approach is a good one. I am following the algorithm from the book "Spectral analysis of signals" by Moses and Stoica and the way I figured it out that it would work is by: - having a method that gets as input the signal and return the frequency estimates - compute the co...

hi guys.. I am in the process of doing a project on implementation of MUSIC algorithm for beamforming. I want to know as to how to create a covariance matrix. For example if we have 3 antennas and we are taking 5 snapshots of the incident signal, then how do we get the covariance matrix of the input data. I know the formula to find covariance of two signals. My confusion is for two sequences...

i've only done really basic work with audio ... so i'm not even sure what to call this? what i want to do is be able to take audio input from a microphone and filter out background noise. e.g. if i'm in my car and have music playing but also want to do speech recognition with a mic. the mic would get my spoken command along with the music being played. then i would have a separate feed of ...

I found out something intriguing recently: Dirichlet's wife, Rebecka, was the sister of the composer Felix Mendelssohn! This is from Marcus du Sautoy's delightful book, "The Music of the Primes," which is as much about math history as it is the primes. A really wonderful tome, Sautoy provides very informative glimpses of many of the mathematicians we in DSP espouse: Guass, Euler, Riemann, C...

Hi, I'm studying dsp and music at the moment and hope to do a masters in this area in the fall. My research proposal is to build a synth with a generic interface. The idea is that the keyboard interface could be used for writing, mouse movements, playing music or whatever. An efficient way of converting finger movements into digital information in other words. Anyway, I'm wondering what...
