Thank you for the test, Allison! You sound good :D

A few things to fix:
-The recording is in stereo but needs to be mono. To make the track mono: select both tracks. Click Tracks > Mix > Mix Stereo down to Mono. To change the setting for future recordings, go to Edit > Preferences > Devices. Under Recording, change Channels to "1 (Mono)".
-There is a bit of background hum. This is a really common thing to fix during editing! Select a few seconds of background noise only (no speech) and click Effect | Noise Reduction | Get Profile. Then select the whole recording (Ctrl+A), click Effect | Noise Reduction again, and use settings:

Noise Reduction: 10 dB
Sensitivity: 6
Frequency smoothing (bands) 6

and click OK.

- The bit rate needs to be 128 kbps and constant. We fix bit rate when we export (to MP3, in our case). So, click Export > Export as MP3. In the lower half of the new window you see "Format Options". You want to first click Bit Rate Mode: Constant. Then, for Quality select 128 kbps from the drop-down menu.

Please fix these things, save, upload and post again in this thread so we can listen again. It is possible that the volume will need to be adjusted up just a little bit at that point, but we'll deal with it then. :) You're doing well!
