I should probably clarify, I'm trying to detect weather or not an orifice releasing air is clogged or not with the spectrum of the audio from a working orifice tending to be in the 1kHz to 5/6kHz region. The thing I'm really having trouble with is differentiating the part of the signal I want...
VE1BLL, the noise profile is not flat, it always tends to be a pink noise spectrum, but can vary between the different data sets. Hence why I want to take a sample of the noise and subtract the FFT of the noise spectrum from the entire signal.
Hi, this is my first post! I work as a water engineer but part of my job is product development.
So, I have a set of many audio files (1000+, will be larger when the project is commercial) which are around 2 minutes in length with around 10s of signal I care about and the rest is noise. I have...
