Hello deakle,

Thanks for the test. All technical stuff is fine with it, except one. Your audio is too hot. In fact, it's clipping all over.

Please reduce the gain of your microphone until you can get your waveform to appear similar to this one:

See how the peaks barely reach 0.5 mark?

Please do another take. You can use the same poem if you like. Or you can use our "Peter Piper" text (you can find it here)

Also, if you install Checker, you will be able to validate your own MP3 files before uploading them.

You're doing well. Just a small adjustment to your process. :)

Thanks for the feedback. I'll re-do my test later tonight.

OK, trying again. Hope this is better.

Hi David,

It's much better in the sense that now your nice voice is so much clearer because it's not clipped. :thumbs:

The volume is too low now. The waveform now looks like a string of beads with the peaks hardly reaching about 0.1 of the maximum.

Well, it's better than before because you can safely amplify it without any deterioration of quality.

You didn't download Checker as I suggested, did you? Please do. It is not always possible to hit the right volume while recording, and while we try (by keeping the peaks about 0.5 of the maximum), we often have to bring the volume into the required range in post-processing.

If you run your MP3 file through Checker, you will know what the perceived volume is, and knowing the target value (89 dB, or anywhere between 87 and 91 dB) you can amplify your track by the amount necessary.

Your second test is measured by Checker to have 73.6 dB of volume, which means you need to amplify it by ~15 dB to get in the range. Please select the entire track, then do Effect -> Amplify... and enter 15 as the value. You should see the peaks mostly in the upper half of 0 - 0.5 range then. Don't forget to save. After that export like you did before, and re-upload.

Thanks for your efforts! Just a couple steps to your goal. :)

Thanks—I did download checker, finally, and I’ve managed to amplify it. Slowly figuring out how things work. Here it is again. (Also posted to Listeners and Editors Wanted forum)
