Also there is a problem with stations using the "Optimod".. All the tracks played, no matter from what source, have the same Apparent sound and eq... quote: It kinda makes it a game of "Cat and Mouse" between the producer and the radio station's engineer !!

Roy There is an FCC rule about the amount of carrier modulation.. so maybe the RIAA could introduce something similar..But don't hold your breath !! |

I know companies in Nashville and in Memphis that record at +2 decibels: that's a really hot signal. One engineer points to hits in the 50's that used a hot signal and said that the main reason it became a hit was because it was LOUDER then the song just played. (This makes no sense; I've worked the board at radio stations--when you hear a super hot signal, the first thing you do is get that meter off the red). Typically, I record at-2.00decibels, NORMALIZE the signal, compare it to other music with a decibel meter, and make adjustments if necessary. I recall doing a session with Johnny Cash in 1957 at Phillips International: Sam insisted that Scotty Moore (the recording eng.) keep the needle on the edge of the red. ---j--- |

Doesn't anyone sell an "auto-normalizing" CD player? It should be a simple matter to compute the average level of a track, and adjust the playback level accordingly, before audio playback begins. |

Earnest - That's exactly what Cakewalk-Sonar does with one click, but I know of no CD player that does that. ---j--- |

The problem is that the normalized sound of any two tracks could have a completely different "Perceived" volume.. I depends on the amount of processing at the mastering stage.. Baz |

Exactly. Automatic 'normalizing' only reads the peaks, not the overall loudness. Steinar ------------------ |

Dr. Hugh.. I'm confused.. you say quote: What is 0 decibels ? with relationship to what reference ? Do you mean +2 referenced to 0Dbm = .775 Volts @ 600 Ohms I always thought that a decibel was an ARBITRARY unit until specified !! By a designator such as Db(m) or Db(V) etc. http://www.audio-technica.com/glossary/#d http://www.phys.unsw.edu.au/~jw/dB.html#absolute

From the first webpage... dBm Decibels referred to 1 milliwatt. dBu Decibels referred to the voltage equivalent of 0 dBm into a 600 ohm load. 0 dBu = 0.775V = -2.2 dBV dBV Decibels referred to 1 volt. My head hurts... |

Basil - Sorry, been away for awhile. Yes, +_2dB based on ref of zero (I record at minus 2 usually). BTW - I'm still enjoying My Guitars and I---nice work! --Hugh-- |

The Normalization technique is basically used to assure that your recording will not be too loud or too soft when one, for instance, plays a CD on the auto stereo; ie, no volume adjustment should be necessary. The alexander mag. article is informative, but check out ArtistPro.com as well. ---j--- |
