Hello there Librivox Users.

I started doing this audiobook stuff back in the summer and have been enjoying it quite well.

I was wondering if you guys had any tips for faster editing? Editing always seems to take a lot longer than expected.

Also, can someone inform me what exactly these sound artifacts are? Is it my mouth? How do I get rid of these easily? Editing takes longer since I have to manually cut many of these lines out.

The artifact you've got there is probably mouth click. While it is slow to process data, this plugin does a great job removing it automatically.

For faster editing, have you explored Audacity macros? While you're editing, always think, "Can I automate this task using a macro?" Macros can do everything from generating noise profiles automatically for noise reduction to doing all the processing to make a recording comply with Librivox's standards (volume, silence at start and end etc.).

A macro I find very powerful and fast for editing is a "Find Clipping" to mark all your mistakes when you clapped/clicked, start at the back of the track and then use the following macro mapped to a hotkey. You would select the portion of the track you want to delete then run this macro:

It will delete the selected audio cleanly as well as the label then jump backwards to the previous label and start playing the audio. It can make editing very fast.

Some people like to use the "punch and roll" method of recording and editing. Essentially, you're editing out the bad parts as you record.

We had a demonstration as part of a Zoom meeting. Here's a link to the video of the meeting, at about the time the Punch & Roll demonstration starts.

I use punch and roll. It cuts your editing time down to almost zero. The link Tricia posted above is a demonstration of how it works using Reaper. I've made another demonstration of how to do it in Audacity: https://youtu.be/K1_Gti3lHaM

I downloaded one of your recordings (Early Cave Men - chapter 07). This must have been a long editing session since there's a lot you had to get rid of one piece at a time. It's pretty over processed to begin with. You are also cutting off the ends of words with your edits. For example, listen to that file at 1:35. You say the line, "that their mothers knew how to make", but you cut off the "ake" at the end in order to get rid of the artifact left over from processing. And there are a lot of other strange noises in there as well. Would it be possible for you to upload a file that is completely raw, unedited and unprocessed in any way? And could you list the equipment you use, specifically, the microphone? It would be much easier to tell what's going on with that information.

I also punch-and-roll record using Reaper. It takes some practice, but once you get used to working that way it easily cuts total editing time in half.

The artifact you highlight does look like a mouth noise. In fact, I used to get something very similar to that that turned out to be caused by a dental problem. I can't tell from your screen shot if it is even audible - some things appear in a wave form that are not.

Thank you for all the advice. I'll be sure to employ these for use in future recordings

There's really not much wrong with the test recording. As for mouth clicks, there are only a few, and they're in the middle of your voice, not in the gaps. This is quite normal and generally not noticeable. Mouth clicks don't usually appear in the gaps between speech unless you're running out of air and have to pop your mouth open quickly to take a breath. If that's the problem, you can find quite a few videos on YouTube about breathing for voice over that cover the issue.
Back to the test file. I only had to apply a minimal amount of noise reduction, get rid of the mouse clicks at the end, and normalize to -4 dB to get a perfectly usable recording.
I think the sample I listened to before was just over processed and full of strange artifacts as a result. It's usually caused by heavy compression and/or excessive noise reduction settings. If you're using Audacity, as a general rule, put the last two settings in the noise reduction dialog to 3 and 0, and don't use a noise reduction amount any higher than you absolutely have to.
As far as your mic, it shouldn't be a problem. Others use that mic without any issues and it's very popular since it's decent enough for the price.
Hope this helps.
