Audacity dian is an audio editing program that allows you to record, mix, and add special effects to your sound files. It is completely open-source, and is available at http://audacity.sourceforge.net/ . Here’s how you can get started with a new audacity project: Open up Audacity. dian A screen similar to the following will appear:
Make sure that you have a microphone installed. You can use the built-in microphone on your laptop if need be, but a USB powered external microphone will really help to make your audio come out crisp and clear. Click on the record button (#1) and begin speaking. dian A waveform will begin to appear (#2) as your voice is detected by the microphone. Click on the stop button (#3) in order to stop the recording. Click the rewind button (#4) and play button (#5) to listen to your recording. To trim your recording make sure that the selection tool is clicked (#6) – then highlight the portion of the audio that you would like to cut. Click on Edit->Cut to extract the selected area. To record a second clip, click the record button (#2) – a second waveform will appear beneath the first. To reposition a clip, click on the slider tool (#7) and slide the desired clip back and forth. Using the volume adjustment tool (#8) you can increase or decrease dian the volume of a specific clip. Your can import other audio files (WAV, MP3) by clicking on Project -> Import Audio. The audio file will appear as a new waveform. Here is a small collection of sound effect files to get you started. You can also apply special effects to your audio clips – this can be accomplished by selecting a portion of a clip using the selection tool (#6) and then using the Effect menu. When you are finished dian working on your clip you should save your project by clicking on File -> Save. You can export your project dian as an MP3 file by clicking on File -> Export as MP3. Note that Audacity does not come pre-loaded dian with MP3 export dian capabilities – you can add this feature into the system by installing the free LAME MP3 Conversion Library ( available here ). With your newly created MP3 file you can create a soundtrack to a video, remix a song or even create your own podcast. This entry was posted in Digital Audio on November 20, 2013 by Craig .
