Phone Audio Practice Recording, Converting, & Publishing Audio from your Smartphone Screencast Guide Here
Smart phones can be an easy way to record conversations in a language class. Andriod phones come with a default recorder and there are many free apps available for Android and Iphones.

Optional Task : Record some audio on your phone. Most messaging apps (Kakao, Band, Hangouts) now support audio message, however exporting those and/or publshing them esle can be challenging. One of the issues with phone recordings is that they are sometimes saved in file formats (like .amr or m4a) that are not easily shared via Kakao, Band, or other apps. There are several ways to convert these files to friendlier formats. (Screencast Guide Here  You can use online converters (listed on the Audio Guide) or upload your phone recording to your Google Drive and install the Driver Converter app by clicking 'Open with/Connect More Apps/and find 'Drive Converter'. I suggest converting that file to an mp3 file. You can also install the Clyp.it app and record that way (although you will not be able to download an mp3 and/or edit the file).  

Audacity & Audio Recording/Editing
AudacityAudacity - a free, cross-platform, open source tool for recording and editing audio.  Installing and Using Audacity - You can download Audacity here. -  In order to export mp3 files with it, you will also need to download and install the Lame Encoder. - In order to import some audio or video formats, you'll need to install the FFmpeg plugin. The screencast below shows how to use Audacity.      Audacity Introduction Screencast
Basic Record, Stop, & Play Controls  
To edit the audio, click the 'selection tool
highlight and then the delete button on your keyboard. You can use the magnifying glass to zoom in or zoom out.  To remove a track, click the 'x' and start again.
 Saving a file as an mp3 To do so, click 'File/Export'
Save as file type 'mp3'.
When the edit metadata window pops up, you can enter information or ignore it. (meta data is the info you would see on your mp3 player when listening to this file).
In the save as window, options allows you to change the bit rate (quality of the file - bigger=larger file, higher quality). 64kbs should be fine. Click 'save'.

Audio Settings Sometimes you'll need to adjust your audio settings in order for you microphone to be recognized. To do so, RIGHT click on the speaker icon in the bottom right corner of your screen. 
Select 'Recording Devices'.  You'll see a list of recording devices on your computer. Click the you are using and then click 'Properties'.  Select the 'Levels' tab and make sure the volume level is not too low or muted. 
To record audio from  non-mic sounds on your computer you can now use Ocam or the the more complicated method of selecting 'Stereo Mix' as your recording source.
Make sure to 'Show Disabled Devices'.
Enable Stereo Mix
In Audacity, click 'Edit/Preferences' and under Devices, select Stereo mix at your Recording Device.
