Using FFmpeg:

Step 1: You will first need to install FFmpeg if you haven’t already installed it.

Next Step 2: Now you will need to open a terminal (or Command Prompt): Open your terminal or command prompt.

Step 3: Now navigate to the directory containing your audio file: Use the cd command to navigate to the directory containing the audio file you want to process.

Step 4: Run the FFmpeg command for noise reduction: Use the following FFmpeg command to apply noise reduction to your audio file:

arduinoCopy code

ffmpeg -i input_file.wav -af “highpass=f=200, lowpass=f=3000” output_file.wav

You will need to replace input_file.wav with the name of your input audio file and output_file.wav with the desired name for your output file.

Step 5: Now you will need to wait for the processing to complete: FFmpeg will apply the specified filters to reduce background noise in the audio file. Depending on the size of the file and your computer’s processing power, this may take some time.

Step 6: Verify the output: Once the processing is complete, verify that the output file has been created in the same directory.
