Does the following make sense? 1. Change tempo 2. Change pitch 3. RMS normalize 4. Limiter 5. EQ remove rattle <-- should this be done before normalize, even first? 6. Boost EQ 7. Paul de-ess 8. Ozone and mix to pseudo stereo 9. Limit again if (8) introduced clipping. I think the rattle-reduction E...

Thanks again. Result attached. ATTACHMENTS audio-excerpt1.wav (1.55 MiB) Anything else? That sounds too sibilant to me. The pattern of sibilance is now too complicated to be corrected by Steve's de-esser , which just has 1 band. Paul-L's De-Esser can have dozens of bands, 5 will do ... settings use...

Re RMS normalize, I found it created so much clipping, however I've played some more, and found that -22 dB produces a track significantly louder than peak normalization, and with just a bit of clipping, so seems to be a sweetspot for my tracks. However, Ozone Imager then adds a bit more clipping, ...

it truncates when there is > 0.01 of true flat-line silence.

I don't see that with "compress-b1.ny" (from the first post of this topic).

Sorry : I thought it was about Chris Capel's original plugin, (which has problems with true silence).

2. Noise level at the beginning and end of the file seems to be greatly amplify after compression. Is there an easy way to fix this? It can sometimes help to add a bit of "padding" at the start / end of the track before applying the effect, then trim off the padding after. Generating a co...

Ok, where should it be put in the chain? Chain is currently: change tempo, change pitch, normalize, ozone pseudo stereo, presence boost, de-ess. Whatever effects were applied here , rattle-reduction EQ should be inserted after that. [definitively not before "change pitch"]. ... Chain is c...

... the mechanical rattle from the mic is something I'll fix for future recordings. Any remaining problems or changes required to the processing already done ... To me that rattle is intrusive. It can be reduced with equalization, at the expense of presence ... reduce-rattle equalization.png reduce...

audio-excerpt1.wav (1.27 MiB) & audio-excerpt2.wav (1.51 MiB) have different problems. #1 has rattle, (on "how to plan and manage" , both before & after), #2 doesn't have rattle. On second thoughts, I think the rattle is mechanical, being generated in the microphone, as it's faint...

audio-excerpt1.wav (1.29 MiB) On that there's an occasional metallic rattle in the 8kHz-14kHz range that will have been exaggerated by the treble-boost, (and possibly made worse by other processing, like pitch-shift). There wasn't any of that on the examples you've posted previously. The rattle can...
