Re: who can add Percival-Tzanetakis Tempo Estimator into our O2014 toolkit ?

Hi Xin Wei,

This is related to what I have been working on for the drum robot. If there is not an existing object then I can make one, either using Marsyas or just implementing it directly in C. Do you need it to run on audio signals gathered with [dac~], or on regular numeric data (i.e. from sensors), coming from say [udpreceive]?

Hi,

For our rhythm research we need a decent tempo estimator as a fundamental tool.

Adrian sent this:


Streamlined Tempo Estimation Based on Autocorrelation and Cross-correlation With Pulses
Graham Percival, George Tzanetakis (Trans. Audio, Speech, and Language Processing, 22.12, Dec. 2014)

It’s implemented in Marsyas (C++), Python and Matlab.

Is this available as an efficient Max/MSP external so we can incorporate it into our apparatus?

If not, who can do this, this Fall,  for Synthesis' RHYTHM research stream?
