What Audacity Can Do For You
- Record live audio. I have seen Audacity used to record live events, presentations, and speeches. It’s also a great tool if you want to email someone a simple audio message. Just plug in your headset, hit record, and start talking.
- Record audio from YouTube. There are tools that allow you to download YouTube videos, but what if you only want the audio? Use Audacity – see the tutorial below.
- Convert records and cassettes to MP3. I’m old enough to remember records and cassette tapes. I once used Audacity to convert all of my music cassettes to MP3. Just plug your cassette player’s line out into your computer’s line in, and off you go.
- Convert between audio formats. Audacity supports Ogg Vorbis, MP3, WAV or AIFF formats, and converts between them. It imports and exports all formats supported by libsndfile, however does not currently support WMA, AAC, or most other proprietary or restricted file formats.
- Create a podcast. It’s amazing how many people get started in podcasting with Audacity, even if they move on to more sophisticated software down the track. In fact, many stay with it.
- Edit digital audio files. Audacity allows you to edit an audio file in many ways, including deleting segments of the file. This is useful for cutting out unwanted audio at the beginning and end of a live recording, and removing inappropriate comments and bloopers during a presentation. Basic editing functions include copy, cut, paste and delete, and also has a drawing tool to edit individual sample points. It has an unlimited undo capability, and allows editing of very large files.
- Visualize and plot frequencies of a digital audio file. Audacity includes a Spectrogram mode for visualizing frequencies, and a Plot Spectrum command for detailed frequency analysis.
- Change the pitch of an audio file. Use Audacity to alter the pitch of your recording without altering its tempo. Or alter the tempo without altering the pitch, so you can listen to lectures and presentations much quicker than they were originally given.
- Combine digital audio files. Audacity allows you to join and layer different audio files into a single file, even if they were originally recorded at different sample rates.
- Add effects to digital audio files. Use Audacity to add reverb and other effects to your audio. Or use it to remove static, hiss or hum. Audacity has some built-in effects, including echo, phaser, wha-wha and reverse, and also supports LADSPA and VSI plug-ins.
- Create multi-track recordings. Audacity supports an unlimited number of tracks. While listening to the existing tracks, you can record new ones, making the program appropriate for multi-track recording. You can monitor volume levels before, during and after recording. Audacity even allows you to record up to 16 tracks simultaneously, making it useful for recording an entire band or orchestra at once.
One testament to Audacity’s popularity is the number of tutorials around the Net that teach you how to use it. Here are some of the best, including some basic tutorials that get you started.
