iZotope has added Diaglog Denoiser feature to lower end version - now $100 off

Not bad. The Dialogue Denoiser works wonders, but the Ambience Match feature in RX4 Adv. is well worth it. Total game changer. It's a huge time saver so if you're planning on doing a lot of dialogue editing (and getting paid for it), Adv. is worth the price.
 
Highly recommended! This is my best money spent in 2014.

I often shoot interviews in conference rooms and offices which are generally quiet except for HVAC noise. With this product it can be dramatically reduced without distorting the quality of the voice. It also removes hiss from low grade pre-amps recorded at low levels. My (acoustic) noise floor is typically reduced by 12dB or more before further processing.

Final Cut X has a feature to reduce "background noise" but is makes everything sound garbled. I'd rather hear the noise. ALSO the white noise of a HVAC is broad band, so don't fool yourself into thinking it can be filtered with EQ.

During an office interview a few weeks ago the subject's desk phone phone rang and the guy just ignored it and kept on talking. Using spectral imaging I was able to paint out the rings to where my client could not even hear it.

On another occasion I was doing sound design for a client who wanted to use a certain recording of birds near a stream of water. She asked if I could remove the stream and was amazed (as was I) that it worked instantly by "learning" a sample of the water alone.

I now have a workflow of processing all my recordings with this software before import/syncing in my NLE. First I reduce peaks caused by coughing or other loud spikes by drawing in clip gain changes. Next I normalize. After that de-crackle to remove all the dry-mouth clicks, then compress with a plug-in. RX hosts all my VST and audio unit plug-ins. The final stage is noise reduction. RX will work within the NLE, but the trade off is that when processing in "real time" it is using up valuable CPU power.

Yes I know it sounds like a lot of work, but it makes a HUGE difference. Attention to audio is one very important and overlooked skill that keeps me at the top of my client's list.

I am using the "standard" version. If I had enough work to justify it, I would purchase the advanced version. Acoustic matching and de-reverbing would be fantastic tools to have in the bag if you find yourself mixing files recorded in various locations. In that situation I imagine it would pay for itself in a very short time.

Download the demo and try it yourself. The only negative for me is the user interface. It does not have that nice "Mac" look or feel, but I guess that is due to cross-platform design.

An alternative may be Adobe Audition. Though I have not tried it, it looks to have a similar set of tools. This might be the natural choice for users of Premire.
