There are some cautions with that. You can't upload massive productions. It will only allow you (for example) 20 seconds of mono WAV or 10 seconds of stereo WAV. Uncompressed WAV (Microsoft) 16-bit is recommended if you want us to evaluate anything because the world's favorite format MP3 has built-in distortion and we can't tell which damage is yours.

There are also restrictions for file types.

Hi, Can you tell me what the floor noise is and give me any other useful info that would help me meet ACX requirements. This is a Yeti mic. I have another large diaphragm mic and need to know which one will work best. Thanks!

Yes, but.

It's a little messy, but fixable in the Audacity tools. Repaired clip attached.

First three sentences and declaration 2/3 down.

It's not noisy. You are.

[loud lip tick] She walked into the bedroom...

...the girl [loud gasp] She walked into...

...behind her [loud gasp] Five minutes later...

I doubt Quality Control is going to pass that for purely theatrical reasons. You can fix some human noises in post production editing, but it might take weeks for a book. There are some tools that can help with mouth smacks, but I think your restricted airway could be a problem.


I like your free-swing delivery. I had a friend from North Carolina who could do that. "OK, you just sit right here, I'll get you a coffee...and a microphone."

I think you'll have to surgically removes all those gasps...by hand.

It can be done. It's intensely painful editing.

Removing them is not just cutting them out or silencing them. One throws off the story timing and the other puts odd holes in the room sound behind you.

I did it by drag-selecting a gasp and then looking at how long the time is (.63 seconds). Then I copied a 0.63 second chunk of normal room sound and pasted it over the gasp. Repeat many times. I also cut out the lip smack at the beginning. That's a straight drag-select and cut.

As a last obsessive act, I removed a bit of silence from between each phrase to "tighten it up" a little.

You are awesome!!! Thanks! I'm going to send you another one with a different mic, paying attention to all mouth sounds and breaths. This helps SO much!

Hi Koz,
This upload was recorded on a large diaphragm mic. The upload I sent you before was done on a Yeti. Is there a difference that you can discern? Which one is better? I have learned how to edit out loud breathes, fill in or take out spaces. Next learning curve will be to cut and paste. :) Really appreciate your help. This should be the last question.

I like this one for voice tone quality. I think your story-telling swing is better, too.

But.

It has a very serious power hum problem.

mmmmmmmmThat nightmmmmmmdressed alike in dark green, bell bottom pantsuitesmmmmmmmmmmm.

What's the microphone and how do you have it connected?
