M-Audio Izotope RX is a very powerful Noise reduction tool. It is able to remove pops, clicks, hums, background noise, clipping, and can even function as a spectral repair tool, when parts of a wave file are missing.
I've only been using Izotope RX for about 2 months now, and it is a tool that every sound editor should have! And if you can take the time to learn how to use it,
you will be well on your way to audio repairing heaven!
There are many tutorials out there, including ones on YouTube that will demonstrate
how to use the program, and it is in your best interest to learn as much
as possible when using RX, because as much as it is powerful, it is also destructive, so beware!
Izotope RX can perform all of the above functions to repair your audio, but it is
even more flexible, as you can preview in real time what your audio will sound like, capture your settings along the way so you can easily go back to a setting that worked
better etc. By using 3 Algorithms- A (Realtime),B, C (Offline), the user can choose to yield better results (slower processing) or by using B or C, or faster processing to get through larger amounts of content in a shorter time period (A). I find that no matter which Algorithm you use though, you will always have to tweek the amount of Noise Reduction and Smoothing to lessen the artifacts created on the original audio.
Izotope RX performs really well, as a declipper, hum remover, and spectral repair tool as well. The user is able to zoom into the spectrogram, and select only a desired frequency band, and isolate that sound for further removal. This is quite convenient when certain noises happen in a higher or lower frequency band, and the user is not forced to affect the original audio in all frequencies.
If you have a waveform which is missing information, RX can also use the information around the selected area to rebuild a natural filler in the audio to make it flow together. Now, this is shear magic!
If you are an editor and are constantly faced with Background Noise, hum from electrical grounding issues, or need to clean up an old recording, Iztope RX is for you!
