Audio Noise on Blaze



Hi

I did try to do some voice recording using Blaze device and I found that the background noise is quite obvious. 

How can I reduce the background voice?

I have attached two audio clips here.

1. recorded by the Easy Voice Recorder Apps.

1563.My recording #4.wav

Here is the Snapshort on how the Frequency Analysis look like.

The source code version is 4AI.1.4-P1 and I hope this will help.
