The video shows us how to use audacity to record audio. Firstly you need to have the software audacity installed in your system and for that Google and search for 'audacity' and after that you get a link to save and install the software. Once the installation is done, open audacity and on the drop down menu the default is set to microphone, change that to stereo mix and copy my settings. Once this is done we will be recording the audio. Go to a site like youtube and press the record button in the audacity and the press play on the video, the audio will now be captured. After recording you can delete off the silent part and add bass boost (if you like) which will increase the sound. After this you need to download the Lame Mp3 dll. It is called the Lameenc.dll which can be downloaded from the internet and this will be in the zip format. After the download, unzip the file and put the .dll somewhere as audacity will prompt you for it every time you try to save the project as an Mp3. After this your file has been converted to an Mp3. Some of you may prefer P2P or torrent clients but this is the safest way. This is the way audacity can be used to record audio.
