The only way I have seen documented to estimate the cross spectrum density is by obtaining the DTFT of the cross correlation of the two signals of interest. With so many spectrum estimation methods available I was wondering if it is possible to estimate cross spectrum using those methods. For example using the MEM (aka Burg), MUSIC, ESPRIT, CAPON, APES, Yulk-Walker, etc. Even in Matlab the o...

Hi everyone, I am doing a project in DOA based beamformer in fixed point DSP. I have a doubt. Can an eigen beamformer be used in DOA based beamformer. The DOA (MUSIC algorithm) estimator calculates the direction of the incoming signal and beamformer designs the radiation pattern such that the main lobe is directed towards the signal of interest and nulls towards the interfereces. Can I use an ei...

Hi Guys, I am new to DSP programming, but I found a good software called BASS to allow me to do looping for music. My problem is that when I pick a start loop and end loop point and then begin looping you can hear a click in there. I was told by someone that this is because my loop start and end points must be adjusted forward or backward to ensure the points are at zero cross. The data I...

So I am working on an onset detection algorithms for music signals. For each group of samples i take I apply a hamming window and each frame overlaps by %50. I take the STFT of the signal. I apply an ideal highpass filter to the signal (i.e., linear weighted frequencies) I integrate the signal to obtain the energy (i.e., each weighted STFT gets summed into a signal value) I need to labe...

Hi Can anybody help me to clear up question about what should be called parametric methods. For example, in some sources the Capon's beamformer (which is also called MVDR and Frost beamformer) is considered to be spectral method in others it is a model-based parametric beamformer (or DOA estimator). The same is about MUSIC. Another question is that if maximum likelyhood is a model-based approach, ...

Sample-based synths are stale and rigid. Any sound effect in action will noticeably quantize and alias the music. They are a hell an earsore for life-wanting instruments such as synth pads and synth fx. The tone of synth pads are generated on FM synths! No wonder pads sound so crappy in samplers. A *real* digital (not analog) FM/modelling synth is a dream! It should be hard-coded and able ...

Hi everyone, I have a question relating to direction-of-arrival (DOA) estimation for MIMO systems. When using an antenna array, would it be possible to estimate the DOA of more multipath sources than the number of antennas in the array? The DOA estimation algorithms used are those based on second-order statistics: subspace-based methods like MUSIC and maximum likelihood methods like SAGE. ...
