Yes, that the is program. I just downloaded and opened up a wave file of a violin note and asked it to extract the formants (after configuring to use 30 formants instead of the default 4 or 5), then wrote the data to disk which ends up being a very easy to read text file. (I've pasted an example below). I'm wondering if the easiest thing would be to create some kind of script to average the values, then to generate an ftable with alternating freq/bandwidth values, then create a recursive UDO to read and use mode or reson to filter. At least, it would give a place to start. (Still need to learn more about Praat though first!). steven frame [872]: intensity = 0.022332281817987687 nFormants = 30 formant []: formant [1]: frequency = 223.347183 bandwidth = 70.222702 formant [2]: frequency = 408.326202 bandwidth = 9.71362686 formant [3]: frequency = 517.510498 bandwidth = 146.2267 formant [4]: frequency = 625.464905 bandwidth = 12.0123663 formant [5]: frequency = 820.949219 bandwidth = 17.6907997 formant [6]: frequency = 1038.27783 bandwidth = 30.0136738 formant [7]: frequency = 1229.69946 bandwidth = 23.6253757 formant [8]: frequency = 1449.45203 bandwidth = 36.9538002 formant [9]: frequency = 1651.75586 bandwidth = 8.41847134 formant [10]: frequency = 1820.4126 bandwidth = 117.126465 formant [11]: frequency = 1871.63281 bandwidth = 620.638367 formant [12]: frequency = 2080.96729 bandwidth = 54.9537277 formant [13]: frequency = 2288.51294 bandwidth = 38.0279846 formant [14]: frequency = 2517.52295 bandwidth = 70.8480072 formant [15]: frequency = 2688.8269 bandwidth = 11.0933828 formant [16]: frequency = 2873.78101 bandwidth = 64.5403214 formant [17]: frequency = 3084.89648 bandwidth = 33.4447289 formant [18]: frequency = 3156.79224 bandwidth = 864.423584 formant [19]: frequency = 3306.52612 bandwidth = 45.5824394 formant [20]: frequency = 3521.06592 bandwidth = 85.9821014 formant [21]: frequency = 3748.93848 bandwidth = 65.4862442 formant [22]: frequency = 3899.48413 bandwidth = 64.3945923 formant [23]: frequency = 4127.94971 bandwidth = 48.9790459 formant [24]: frequency = 4324.48193 bandwidth = 17.0357494 formant [25]: frequency = 4517.6543 bandwidth = 89.0149231 formant [26]: frequency = 4718.92725 bandwidth = 59.361805 formant [27]: frequency = 4905.62842 bandwidth = 749.738403 formant [28]: frequency = 4980.18848 bandwidth = 182.575287 formant [29]: frequency = 5164.46094 bandwidth = 53.119297 formant [30]: frequency = 5361.16113 bandwidth = 76.9371033 On 9/28/07, Dave Seidel <da...@su...> wrote: > Hmmm, I'm not familiar with PRAAT.
