I’d like to track the first two formant frequencies of a live vocal input, for doing a rough vowel estimation. Apparently, Linear Predictive Coding is the proven method to achieve that. So I’m looking at the LPCAnalyzer ugen from the plugins, but from reading the doc, I can’t figure out how to collect the analysis info. It looks like the ugen does a resynthesis but doesn’t share the analysis parameters it computes.
Has someone figured this out before? I’m also interested in an alternative method for formant analysis if you have some advice…
