I'm hoping to make some formant synthesis patches with my modular soft synth Moselle. http://moselle-synth.com
I've looked around for formant tables and find tables with more vowels and fewer formants, or fewer vowels and more formants. Tables with amplitude seem to have fewer vowels and only one I've found shows Q. But the Q (as shown in CSound documentation, one example pasted below) is specified in Hz. The parametric (const and non-const) filters I'm using need a Q input. Is there a formula to convert Hz into Q? Failing that, is there a standard amplitude at which which a bandwidth would be measured in Hz? EG, at -6dB or -12dB or something? If so I could just eyeball it on a graph. Final question: does anyone know a more comprehensive set of such data? This CSound data is great but only covers 5 vowels. Frank Sheeran *soprano "a"* freq (Hz) 800 1150 2900 3900 4950 amp (dB) 0 -6 -32 -20 -50 bw (Hz) 80 90 120 130 140
