Windows Voice Recorder is a simple but effective program that comes pre-installed with Windows and can be used to record audio directly from your computer's microphone. It also has a rudimentary editor you can use to trim unwanted bits from the start and end of the recording.

• In the Windows Settings search box, type Sound and press Enter. In the search results, select Sound Settings.
• In the Input section, use the input device drop-down menu to choose your microphone, then close the Settings window.

• Select the Record icon on the left side of the screen to begin recording.
  In some installations of Voice Recorder, the Record icon may shift to the middle of the Voice Recorder window when you first open it or if you have not previously made any voice recordings. Once you have created recordings, the Record icon will appear on the left side of the screen.
• While you’re recording, you can select the Pause icon to temporarily hold recording, then select Pause a second time to continue, recording to the samefile.
• When you’re done, select the Stop icon.
• After your recording is done, you can select the recording file, then select the Play icon to hear it played back.
