Hello!

I'm planning to run an experiment with band-pass filtered speech. I would like
to
know how exactly I can filter the sound files in Praat with the following
specifications:

1. low-pass cut-off frquency of 310 Hz
2. high-pass cut-off frequency of 260 Hz
3. decay function (for two filters linked in tandem) of 12 dB/octave.

Any help will be greatly appreciated.

Miguel
