This is echo, so reverb reduction tools won’t help. The echo is pretty loud, which makes it hard to fix. Here’s my best attempt with custom-made tools: 9746_resultdeecho.mp3.zip

To remove a single node, Alt-click on it.
To apply and remove the whole clip gain envelope, just hide it – RX will behave as if it’s baked into the audio. Or, apply some trivial operation like gain at +0 dB – it will bake in the clip gain.
To remove the whole envelope without applying it, press Ctrl+Shift+Bkspace (or use the right-click menu).

Rich, I’m not sure if you’ve seen, but there are some materials on RX at iZotope’s web-site:

[Bob Peterson] “Version 3 has dropped the scan button from the gain control.”
There’s now a key combination Alt+d for scanning levels:

This is definitely a food for Denoiser, not Hum Remover. Here’s what can be done in RX: 5718_5717cheriespresentationsamplerx.wav.zip

Hum Removal module is just a set of notch filters. If they muffle your audio too much, make sure that their frequencies and Qs are set correctly. Perhaps your Q is too low and filters cut too much material around the hum. In many cases, use of the Denoiser module is more justified for hum removal, as its adaptive filters can sense the presence of speech and accordingly control the amount of reduction.

Post a sample here that is a few seconds long. We’ll suggest you the right settings. Generally hum is more effectively treated by the Denoiser module, using algorithms C and D. Train the denoiser on a sample of hum (make it as long as possible, but still containing only noise) and adjust your Tonal/Broadband Reduction sliders for appropriate treatment.

You should be able to see them in a spectrogram and select for manual amplification. However you may also want to try an automatic approach with a transient shaper (which is not a part of RX).

It was completely automatic! (in fact I did not even listen to Set1 because I had to remotely process it from home on my office PC).
However I had to modify the Declicker detection algorithm to work better with this type of clicks. Hopefully the next version of RX will have this improvement integrated.
On RX vs. SL: I think that RX has a huge advantage for restoration work. SL is perhaps more flexible for spot editing, but RX has automatic tools that specifically target noise reduction.

No problem. Here’s the result: Set1.zip. Let me know if there’s anything else to process or if I’ve missed something. Good luck with your release!
