Audio clipping detector
The higher the dB reading the more distortion. It's at 0 dB that analog audio starts to distort. Audio that exceeds 0 dB is called 'overdriven' audio. With analog audio it was determined and standards were set so that a reading of 0 dB on a VU meter was the highest volume level before audio distortion sets in. Changing the volume will not change the dynamic range.Īudio volume is measures in decibels, dB. Dynamic range and audio volume are two different elements of audio. This difference in dynamic range between the two different CDs happens without your touching the volume knob on your stereo. Change the CD to a 'Books on CD' with the narrator reading text and you might find that the volume level is fairly consistent. This range from quiet to loud is called the Dynamic Range. If you think of Classical Music, it can have quiet parts were only one instrument is playing and other parts that are very loud with all 130 members of the orchestra playing. As you know, there will be parts of the program that you are listening to that will be softer than the rest. You have the volume knob set to where you like it. You are driving along in your car listening to the CD player. There are several different elements that we need to look at when working with Digital Audio in FCP. I should point out that there are a number of excellent FCP books out there and you can find reviews of these book at this web site and at the lafcpug web site.

All the authors had to do was read the Final Cut Pro manual before writing their books.

because in both the FCP 2 and FCP 3 manuals there are complete audio sections that cover all this correctly.
I was absolutely shocked to find that in some of these books the information given about digital audio, setting peaks (volume), is so completely wrong that following the advice given is a guarantee to complete audio disaster. I have been reading a number of the new FCP books that are hitting the market. The discussion that follows is for Final Cut Pro users and is not meant for audio pros.
