New release

[piotrgregor]

Hello!

I would like to share a news that I started a work on a new version of libmusic. This comes as a result of my recent re-research of the MUSIC, which comes as a result of my long lasting desire to answer all the questions about this algorithm that I had left without knowing the answers, as a result of my engineering thesis and because I want to use libmusic in a bunch of new cases.

There will be plenty of improvements including:

• specify (pure) signal and noise space dimensions (you can choose number of signal and noise vectors separately)
• get power and amplitude estimates
• get frequency estimates by rooting each eigenfilter (computing Z-transform of eigenvector and finding it's complex roots)
• buffer a single frame in lmtool and run detection on each sample
• code refactoring so DTMF related code won't confuse people anymore

Please share your comments, ideas, requests and questions!

The work is currently at a MATLAB stage and you can trace it here
