There is white noise in the background of this recording, but the directions stated that it is best to submit raw and unprocessed files for the 1-Minute Test.

Hello Ian

thank you for starting with a one-minute-test. Always good to get the technical things sorted out before launching into a bigger recording.

As far as your reading goes, it's absolutely fine, you have a fluent way of narrating which is nevertheless easy to listen to and follow. Perfect for audiobook narration. :)

Unfortunately there is a lot of background noise, because, as you mentioned, you sent us the raw file. Could you please do a round or rather two of noise-cleaning and re-upload, so I can have a second listen ?

In case you are not familiar with Audacity's noise-cleaning function, here is a step-by-step:

> highlight a small portion of the white noise
> go to effect - noise reduction and press "Get Noise Profile"
> then highlight the entire recording
> again go to effect - noise reduction and this time press OK

I think you need to repeat this twice to get rid of the worst of the noise. A good thing would be to check for the source of this noise and try to cancel it somehow. Closing windows against traffic, etc.

A second thing I noticed is that your volume is just inside our required volume limit. We accept anything between 86 and 92 dB (preferred average: 89) and yours barely sneaked through with 86.2. :mrgreen: Now after the noise cleaning the average volume will have dropped, so you will surely be below 86.

So after noise cleaning, you'd need to amplify your file by at least 3 dB to pass the test.

Step by step again:

> highlight the entire recording
> go to Effect - Amplify
> input at least 3 in the slot and press OK

You could check whether the microphone icon in Audacity has the slider all the way to the right on the + sign for maximum input volume.

Please reupload the edited file in this same thread, so I get notified when there is a reply.

thanks and good luck :)
