Hello
I have the experience of 10 years in audio processing filed.
I read your description carefully and have the some questions.
- do you know the features of the external voices,i.e frequency band, F0, pitch ... ?
(I need as many features as possible.)
- can you send me the mixed voice and the external voice to be filtered?
if you send me the sample voices, I will let you know the filtering result after one hour.
if the result is good, you can award me the job.
Thanks
