How do you remove that metal-water noise from a recording?

Hi, I hope you know what kind of noise I mean…I recorded with something with my iphone and after normalising and reducing noise there´s still that waveless noise at certain places in the recording…
Thank you!

I recorded … something with my iphone

What were you recording? iPhones have two live sound recorders. Voice Memo which can have problems like that and Music Memo which has no processing.

Talking in a wine glass or milk jug.

That’s compression, noise reduction, or echo cancellation distortion and it’s permanent.

yes, on a voice memo with a plugged in microphone. Have never used music memo, don´t even see it on my iphone…

so I can just remove it by cutting that part right?

don´t even see it on my iphone…

It’s an optional download.

I wonder what the phone thought it was curing. What are you recording? Were you in an echoey room? I’ve used Voice Memo in noisy restaurants and I thought the voices were going to be terrible, and they came out very reasonable.


Talking? Singing? Were you listening to yourself at the same time? Echo cancellation can cause very serious distortion problems.

You can edit out the damaged parts if the show can handle it.

Koz

yes I was talking (i.e. reading a written script;) I opened the doors of my closet, sat into it and placed a blanket under the mike that was on the height of my mouth, wasn´t listening at the same time… but I did kind of pulled the doors to have “a small room” :laughing:
Not sure whether that did more harm…next time will tape the door with a foam or something…
Will edit out what possible what not stays…
Thank you!

Post some of the bad sound next to good sound. Maybe we’re talking about two different kinds of sound damage.

Koz

that was the edited version, if you don´t hear them great! have attached some on the beginning of the recording

btw. the overstressed ending of the word e.g. feelin GGG I can only fade out right?

Thank you!

We should be careful with sound samples. I’m not always listening on the Office Killer Sound System.

That’s automatic voice processing. It may be all the tools trying to figure out what’s happening. If you speak normally, the tools can usually hide and do their job without being obvious. You are doing a theatrical performance and they don’t know how to deal with that.

The silent portion at the beginning of Breathing Awareness 2 is very different from the silences between your words and phrases once you get going. That long gap is also full of odd bubbling and gargling. That’s auto noise reduction.

I don’t think you can turn those corrections off. So you have two options. See if Music Memo is still available. It doesn’t do any of that. Or you can fake this one out.

Announce a slate or lead-in. “This is Thursday and I’m going to perform Breath Management.” Pause and then go into the performance. If there is going to be odd sound damage, it should happen at the lead-in not the actual show. You can cut or edit out anything you don’t want in the final show. If you do a bunch of these, that also has the advantage that the date and show title is burned into the performance sound file.

Fair warning if your show features a lot of long gaps or silences, it still may sound funny. Normal speech doesn’t have long gaps. Changing the sound recorder is the only option.

And one other hint. When you get to the end of a raw reading, Export it as a WAV (Microsoft) 16-bit sound file. That’s the backup so you never have to read it again if anything goes wrong. Make a copy of that on a thumb drive, external drive, or cloud drive. You can make a WAV file into anything else, but MP3 files start falling apart and distorting as you do editing and production.

Edit a copy of the WAV.

Koz

got it, edit WAV version!

On the beginning I had thse little weird sounds for you to hear them than real silene and then I the real recording started, will be okay, it´s a relaxation for youtube

Thank you for your help

will be okay, it´s a relaxation for youtube

You should be careful about posting sound errors. They can wake you up just when you’re getting relaxed. You don’t want your calming presentation to turn into a class on technical sound mistakes.

This is a big deal with the audiobook people. Book readings are inspected for distractions and any mistake that will take the reader away from the story.
