Wavegain vs. MP3Gain
Reply #99 – 2003-07-18 09:07:02
What I am getting at is the situation about losing details past a certain threshold on the music, regardless of the dB, I do understand what the WaveGain default is, but that doesn't mean it is the only level to be used. Someone pointed out that if one was to later amplify the music they have encoded and --scale'd to a certain lower level, the details that were too quiet or below the cutoff that were removed in the process could possibly be noticed. I guess from your point of view, that doesn't matter, i.e. the detail loss is not going to be very perceptible if at all, with the modest drop to 89 dB. All I am asking is what is the point in amplifying this music where the details lost could be percieved? I guess it would depend on how overly loud the original recording was. For example, say the original recording was on average 98 or 99 dB. Once we scale the volume down to 89 dB, there is a 9 or 10 dB cutoff using this method. Now, if one then amplifies this music on his portable back to the volume it would have played at if it had not been --scale'd, there is most definately a loss in sound. We know this, but we don't know how significant the loss is; we have not tested it thoroughly. How can I be sure that the music is NOT amplified to or past this point though? You said it would be difficult to measure on a portable. What are some methods though? Again, I would assume that it would all depend on the loudness of the original recording for determining the amount a -scale'd mp3 could be amplified to without perceived sound loss, but in practice, how can we find out acceptable amplification limit? Is it too unbelievably high for anyone to care?
