File --> Open

We position ourselves at the moment we want to start recording.

Selection: Start

Audio --> Save

If the recording is not as precise as we want, we can use audacity to trim it more accurately.

This software is very easy to use, with the selection tool we can trim the audio at the moment we are interested in, then we paste it into a new audio file:

File --> New
Tracks --> Add New --> Stereo track
Paste and then File --> Export

We save it as “file”.mp3

If the audio is too low, we can increase it with the mp3gain utility.

With this, we would have everything done, easy and fast, what more could we ask for.
