So glad your here. My name is Luke and I'll be taking over your test today. I've got a few things that your going to need to correct however before you go and record.
1) Volume: We need 86-92dB with 89dB being ideal. Your at 93.7 (so close!) this is what we need to do
Select the whole file in audacity
Go to effects>amplify
Type -5 in the top box
2) Noise Reduction: Next up lets reduce your noise. It was at 36 but now it is at 40 (which is quite loud)
Select a small amount of your file with no talking in it
Go to effect>noise reduction
After that go back and select the whole file
Head back over to that Noise Reduction page
NICE! So now you have a file that sounds amazing: 2 more quick things (these will all be fixed in the export menu
1) Change the Bit Rate selector to CONSTANT (you are using the default of VARIABLE)
2) You will see a grayed out bot become clickable-change the BIT RATE to 128kbps
Now go to export.
I've taken this test over so I will be notified when you post a new link. I'll be back once those issues are corrected
