+Audacity quick tip: quickly remove background noise
+======
+

+When recording sounds on a laptop — say for a simple first screencast — many users typically use the built-in microphone. However, these small microphones also capture a lot of background noise. In this quick tip, learn how to use [Audacity][1] in Fedora to quickly remove the background noise from audio files.
+
+### Installing Audacity
+
+Audacity is an application in Fedora for mixing, cutting, and editing audio files. It supports a wide range of formats out of the box on Fedora — including MP3 and OGG. Install Audacity from the Software application.

+
+If the terminal is more your speed, use the command:
+```
+sudo dnf install audacity
+
+```
+
+### Import your Audio, sample background noise
+
+After installing Audacity, open the application, and import your sound using the **File > Import** menu item. This example uses a [sound bite from freesound.org][3] to which noise was added:
+
+Next, take a sample of the background noise to be filtered out. With the tracks imported, select an area of the track that contains only the background noise. Then choose **Effect > Noise Reduction** from the menu, and press the **Get Noise Profile** button.
+

+
+### Filter the Noise
+
+Next, select the area of the track you want to filter the noise from. Do this either by selecting with the mouse, or **Ctrl + a** to select the entire track. Finally, open the **Effect > Noise Reduction** dialog again, and click OK to apply the filter.
+
+![][5]
+
+Additionally, play around with the settings until your tracks sound better. Here is the original file again, followed by the noise reduced track for comparison (using the default settings):
