Seeing this article helped me to decide to take an interesting approach to incorporating both digital and analog records which were converted to MP3 files to be played on a flash drive through my new car's Bose audio system. Being able to have instant access to my entire music collection is cool, but my recordings are hopelessly divided in terms of their dynamic audio range. With vinyl records recorded to cassette tape, prerecorded cassette tapes, and of course CDs. A good ear can certainly detect the difference, but I found that with this particular audio system, the most "compressed" recordings converted to MP3 format were not only noticeable, but actually sounded lower in volume.
So what I'm experimenting with at the moment is to take a source originally transferred from a cassette tape (the rock group "Foreigner") and simply boost its gain by 3 using Audacity 2.0. While it won't actually change the inherent audio compression of a cassette tape, I'm wondering if by boosting the gain by "3" it may "fool my ear" somewhat with a more pronounced sound level closer to all the CDs I've ripped to MP3 format. At least enough so that it doesn't flat out sound lower in volume alone. Anyone understand what I'm getting at?
Of course I just made the alterations the other night and haven't had the chance to test them out yet. Just wondering if I should expect some degree of "clipping" for doing this. LOL..I guess I'll find out.
"Gain is one of the harder terms to define, mainly because its used in a lot more places than just the audio world. Quite simply it means an increase in some kind of value. So for example, you can have a power gain, voltage gain, or current gain; and they all increase those respective values. Typically when referring to gain, we refer to transmission gain, which is the increase in the power of the signal. This increase is almost always expressed in dB (decibels). This could be the increase in the raw signal from your guitar or microphone before it goes into any of the other electronic components. For the curious, here’s the equation to calculate gain:
Gain = 10 x log (Power out/Power in) expressed in dB."
