Your test has quite a lot of AC hum in it -- peaks at 120 & 240 Hz. Quite audible even where you are speaking. The recording is otherwise fairly clean. It might be possible salvage your hours of recording work using Audacity's noise-reduction plug in, or a filter based on those noise peaks but it will have some effect on the sound of your voice.

Do you have the unedited original recordings?

But before you do any additional recording you need to track down the source of that hum and fix it. This is where we ask you to tell us about your kit and how it is all connected. What kind of Microphone, preamp, computer, etc. Is there a fan, refrigerator or other motorized device nearby your recording space? (I'm guessing not, this sound like hum induced directly into the signal from the power lines to me.)

I did not save any of the recordings unedited 😭 huge lessons learned in my first recording. The recordings I submitted to add I used the noise reduction setting after taking a sample
Of the recording with just background noise and then put in 100 in the noise reduction box.

I believe it is because there was a fan going in my room during the entire recording :(

Where do I go from here?

Have I told you how much I appreciate the help?!

I will admit that I came late to this party and so didn't listen the sample (processed) clip before now.

Was the fan on the entire time you were recording or only part? Or only for that second test "raw" test clip?

I'm a bit surprised that the objection was with the signal to noise ratio, since that is clearly just fine. But it sound like you must have used the noise gate in addition to the noise reduction or something similar. The voice coming out of dead silence effect is known to trip the ACX alarm bells.

I'll defer to others as to whether or not there's a way to salvage it.

Thank you for your input.

The fan is on the entire time, even when I did my test sample. I wanted to keep everything the same for you to hear.

My fingers are still crossed it can be salvaged. Any advice is so much appreciated!

Re: Noise Floor- will pay for help

Literally, if someone is willing to help me fix the noise floor on these to make them usable to submit to ACX I will pay $30 per hour.


I’d love to learn what I did wrong and how to edit these files properly for the future so I don’t run into this again, but want to give this customer the files they’ve been waiting for ❤️

I forced it to pass technical conformance, but you sound like talking into a milk jug over a bad cellphone (attached).

I don't think we can make your raw readings pass voice quality and we can't take effects out of a finished production.

If you're throwing bux, throw them at a real studio. Walk in, record the work and walk out. You can certainly stick with us here, we have a good track record for getting people published, but it could take weeks. Nobody is going to publish by Monday in my opinion.

There is a sister forum posting to yours having troubles getting his voice stuff up to ACX. We've been the first ten days just getting his microphone and environment to work.

— No, you can't have a noisy computer running in the same room with your microphone.

— No, you can't leave Windows Voice Processing running while you announce. That's probably what's giving you that milk jug sound.

— You can't fix everything with filters and effects. ACX hates that.

Clearly I have no idea what I am doing
That's not a problem. We can fix that.

We can't fix: "I need it by noon."

You're on your own there.

Any hits on your email? It's usually a bad idea to leave a working email address on the forum. It attracts bots and spam. Have you gotten any ads for new kitchen cabinets in Manchester?
