I build musical instruments. We build one instrument with a very high frequency that is annoying to practice, though it is used extensively in orchestral performance. We want to make it more accessible to the general playing population. My idea is to make headphones that drop the pitch of the instrument by FFT an octave lower. I wonder if it is possible to modify a pair of noise cancelling headphones for this use.

Hello, My understanding from your description is that your pitch is too high and annoying and you want to lower it (an octave) to make it more pleasant. There are different ways to do that like a frequency shift. I do not understand why you need a noise canceling headphone. The purpose of a noise cancelling headphone is suppressing the environmental noise not a frequency shift. Anyway, I will be happy to help you. I am a professional DSP designer and also working on speech processing (both theory and implementation). My bid price and timing is just a place holder until I get more information about your project. Thanks.
