Flanger :: Flanging :: Flanged

<BODY> <h1>Flanger :: Flanging :: Flanged</h1> <h2>Summary: Flanging has a very characteristic sound that many people describe as a whooshing sound, or a sound similar to the sound of a jet plane flying overhead. Flanging is generally considered a particular type of phasing which is another popular effect. Flanging creates a set of equally spaced notches in the audio spectrum. Phasing uses a set of notches as well, but the spacing of them can be arbitrary and the notches in a phaser are usually created using allpass filters.</h2> <p>A Flanger is an audio effects unit that creates a flanging effect. Flanging is an effect that is achieved by mixing two identical signals and introducing a small time delay to one of the channels. This time delay is gradually changed and produces a comb filter effect. Peaks and troughs occur in the resulting sound based on the harmonic relationship caused by the varying time delay. If a feedback loop is employed then a more resonant effect is produced. Flanging differs from phasing, which is another similar time domain effect. Flanging tends to produce a more even sound while phasing has a more random unstructured sound. Supposedly, Flanging was originally created in recording studios by using two large reel tape recorders and holding a finger on the flange, or rim of one tape reel, varying the finger pressure, and in the process developing a flanging effect. The manually created effect that became popular in the 1960’s and 1970’s was later replaced by analogue and digital effects devices, sometimes pedals, and sometimes rack units.</p> <p>Flanger :: Flanging :: Flanged</p> <p><a target="_blank" href="http://www.wineauction.co.uk">Wine Auction</a> | <a target="_blank" href="http://www.edfenergy.com/powerup/keystage2/house/page3.html">Electrical Safety in the Kitchen</a> | <a target="_blank" href="http://www.ebbs.co.uk">Ebbs</a></p> </BODY>
