I want to remove all these [high waveform] (there are about 8 in this 5 minutes track, which I bookmarked), because if I select all > effect > Amplify, It only amplify [about 3.2 db], but if I exclude those high waveform, I’d be able to Amplify [about 5.6], which is what I’m trying to achieve in the whole track.
Just a comparison of waveform [excluded vs included].
I’m working on a 1 hour track that contains about a hundred of high waveform. I think removing them one by one is not a good idea.
I’m using Windows 10. Audacity 2.3.0
What’s the work?
You also have the Left sound louder than the Right. Did you want that?
You can use the two AudioBook tools, RMS Normalize followed by Limiter.
RMS Normalize has to be installed separate.
If that’s an audiobook reading, you can Split Stereo to Mono (Using the tools under the drop-down on the left), delete the Right track and follow the whole audiobook process.
Sometimes that’s perfectly normal. For example, in musical recordings there can be loud accents or crescendos.
In fact it’s normal in ALL real-world sounds, but professional voice recordings are evened-out (with compression & limiting) and modern pop/rock/rap recordings are compressed to death (removing all dynamic expression).
If this is a commercial recording (vinyl or tape, etc.) this is the way it was intended (assuming the peaks aren’t vinyl record “clicks”). But, you’re free to edit as you wish.
…So it depends on what type of recording you have and what you’re trying to accomplish.
I think removing them one by one is not a good idea.
Sometimes that’s the best way because you have complete control over what’s done. The main/first task of a recording/mixing engineer is to control the levels and in post production (after recording) that’s done with “automation”, like the [u]Envelope Tool[/u]. The “trick” is to fade-up and fade-down the volume so there are no sudden-obvious changes.
After the volume is adjusted/smoothed-out you can use compression and/or limiting if you wish. Or, if you are not that picky about the recording, or if you are just in a hurry, you can skip the manual adjustments.
