Noise Reduction In An Audio File Using Python
Solution 1:
If you want to reduce noise the audacity way, to my understanding, you should program your algorithm using scipy filters provided by scipy library.
Besides that pyaudio
is one dedicated library for audio analysis and here is a kickstart tutorial.
If you are not restricted only to Python
, you can check out on Essentia. This is by far an exhaustive library for music and audio analysis.
Nutshell: While python libraries provide functionalities, it is you who should code your noise reduction algorithm (tailored to your needs). May be you can follow the audacity's approach.
You can refer this question for better, technical/implementation, clarity: Noise reduction on wave file
Good luck! Try to be precise and post questions focusing on implementation pertaining to programming languages rather than generic things.
As a general guideline: Understand the behavior of your noise and then you can choose your noise removal strategy accordingly.May be you need a simple low pass filter or high-pass filter.
