Hi All!

Here is my 1 minute test! https://librivox.org/uploads/tests/test_erf10.mp3

I used audacity, I have a Macbook Pro, and I used a built-in microphone.

Thanks for taking the time to help me out! :)

Welcome!

It sounds good! There are some technical settings to change, however. :)

1) Your volume is a little too low. You clock in at about 85 dB, and we aim for 89. Try bumping your mic slider up another 1/2 to 1 notch.
There's a plugin for Audacity that will tell you how much to amplify your recordings, or how far off you are from "ideal" volume. It's called ReplayGain. Instructions for installing and using it are on this page: https://wiki.librivox.org/index.php?title=Measuring_Volume_within_Audacity

2) The recording is in stereo. To change all future recordings, go to Edit, Preferences, Devices. Under Recording, change Channels to "1 (Mono)".

3) Bit rate is variable; it needs to be 128 constant. This is set when you export to MP3. When you go to export, on the screen where you enter the file name for the MP3, change the Bit Rate mode to Constant, and the quality should be 128 kbps. You should only have to set it once; it'll remember the setting until you change it again.

Try making these adjustments, then post another test. Please leave a few seconds at the end when the mic is on and running, but you're not speaking. I'd like to check your background noise, which is harder to do without a spot where you're not speaking. ;)

Use the same file name as your previous test, and post in this same thread when it's ready. :)
