Hi Len, welcome to Librivox

You're sounding great but you do have some tech specs to fix. I'm not sure what softwware you are using so i will just give instructions for audacity.

The bit rate should be 128 kbps. When you export, change 'quality' to 128 kbps

The recording should use a constant bit rate. When you export, change 'bit rate mode' to 'constant'

The volume is too low at 83.6dB. We aim for 86 - 92dB (with 89 being the goal). You might want to turn up your recording volume and/or make use of the amplify effect.

Once you've correct these issues please upload the test again and post the link here

Thanks for the feedback Ashlie.

My second attempt is ready for review.

I had previously maxed out my recording volume in Audactiy, so this time I increased the gain on my blue yeti - but, I have no idea how to check the incoming db. Hmm.

I corrected my export steps to a constant 128 kbps.

Hope this helps.

Len

All is correct now except for volume. This time it's 85.3. I forgot to say, the checker tool can be found here https://cgjennings.ca/projects/checker/ it is able to tell you the volume of recordings. You can also guess by eye in audacity. The peaks of the waveform should reach to around 0.5 and -0.5 on the numbers to the left.
