Detecting Specific Sounds (Frequencies) with Python
0
I want to record sound of a machine and want to detect if its present in another sound file that I record.
I am able to record the sound of the machine and the sound file that I want to detect its presence.
I am also able to take fft of the sound files, however I dont know If I should check specific frequencies or check it in time intervals.
Can I implement it with aubio or is there another way?

What is the machine that you are recording? Do you mean the very same record of the machine or record of the same machine?

Record of same machine. I want to detect the source of the noises in the room automatically. So in a room first I record a sound in wav format. There were no dominant noise exist (assume silent), next I record a specific noise (caused by audio jack from speaker). Now I will write a program which records sounds in a determined interval, then check if the noise (audio jack noise) exist or not. So in basic; how can I compare 2 wav file and figure out the additional sound?

If you neglect the reflections, you should create a noise signature and compare it the your reference. This task is not trivial and requires solid knowledge in many fields. To understand how such signature can characterize, I suggest you to review the following work: Antoni, Jérôme. "Cyclostationarity by examples." Mechanical Systems and Signal Processing 23.4 (2009): 987-1036. Good luck

Thanks for the answer, Since this only a small part of my project, I thoughed that I could compare two sound files with aubio or any python application. Is it possible or there is no such application to do that?

I am not familiar with such a program. Maybe you should reconsider your project content or reevaluate the time you want to dedicate for this section.
