This is a documentary. You can get away with noise in the production audio, and people will accept it. They key point is whether or not the audio is intelligible. Listening to that example you linked to, I would suggest you leave it alone. The noise floor, while present, is not interfering with my ability to pick out the phonemes. Give it some EQ to ...

What is your use case scenario? Field recordings or vocals? You can if you have the advanced version of 2 or 3. You could also use the 'envelope' function to create a frequency curve that allows you to attenuate noise in a specific frequency range. Highly useful function especially with complex material (with loud low or midrange sounds), because it makes '...

Without knowing what you are recording: If the main problem is rumble sound you could use a high-pass filter - that is if what you are recording isn't using a low frequency range. Try with values such as 60-80 Hz as a start point. In you record vocals/voice you can try starting from 100-200 Hz. Try then to apply a low-pass filter to remove noise in the ...

Firstly, do any and all processing in WAV files. If your source material is on CD, then rip to 44.1kHz/16bit WAV and process at 24-bit in your software. Do not transcode via mp3. Tracks like 104b should be discarded. There is nothing you can do with files like this. The studio has not done their job properly. They have recorded the transfer with input ...

In the case where your two audio signals S1[n] and S2[n] are of same length, and we are speaking of discrete time, discrete value signals, the DFT being a linear transform : DFT (S1[n] - S2[n]) = DFT(S1[n]) - DFT(S2[n]) It means that subtracting the spectrum of S2[n] from the spectrum of S1[n] and transform back into time domain signal will produce the ...

You could use a noise gate. Basically, a noise gate sets a threshold, below which there is silence, above which, the sound can pass. Of course there are other possible configurations involved that will allow you to keep the gate from being a harsh on/off etc. If the background noise you're trying to eliminate is relatively quiet, and the signal you're ...
