How would you react if the next time you walked into a restaurant you’d never visited before the head waiter not only greeted you by name, but also reeled off your address?

Secret Tips For… Audacity

Record web radio, get rid of crackling noises and remove long silences

Record sounds playing on your PC

Free audio-editing program Audacity (www.audacityteam.org) is great for editing digital files from your music collection as well as voice recordings. But it can also record any audio playing on your computer – for example, an internet radio station, a YouTube video or an iTunes song.

To start recording, open Audacity, select Windows WASAPI in the Audio Host dropdown menu and click the record button. Once you’ve made your recording, click the stop button. If you’d like to listen to your recorded audio on an MP3 player or smartphone you should convert the audio file to MP3 (see next tip).
