Do we have a new "Mission Statement" here ??
I'm not following your logic here.
I am chiding you Myke, because you have never HAD a mission statement.
There have been many posts to this thread so far which have helped to
move my hypothesis closer to being proven false or true. I have no
desire to change my mission statement and don't understand why you
believe that I do or have or even intend to.
What have I learned?
1) Pre-"normalizing" a WAV to a higher initial amplitude *should* enable
more frequencies from the source data to successfully "jump the hurdles"
imposed by the Absolute Threshold of Hearing filtration mechanism of
most lossy compression schemes as the data is being compressed into a
destination file or form such as MP3, AAC, or MiniDisc.
Then I must assume that you have chosen to deny the high number of replies
that state otherwise.
2) With regard to MP3s, VBR encoding is most likely preferable over CBR
encoding
Very Good !!! I picked up on that as well. :-)
3) Larger bitrates provide more room for data storage than do lower
bitrates, therefore, greater potential for "better sound" with them exists.
Since you're stuck on a dial-up connection, I suppose that I'll understand
why you may not have know this from the first day you even thought
about the word MP3 - or had not seen and listened to the various bitrate
results using your encoding software.
The varying quality of the radio samples on your website would have led
me to believe that you had already used more than one bit rate.
4) More than likely, greater bitrates also lessen the need to be
concerned about whether one should choose VBR over CBR
when encoding an MP3.
Perhaps. This is over my head and I didn't garner this impression.
5) Software utilities such as MP3Gain can be used to achieve a nice
balance in loudness levels across wide ranges of MP3 which have been
encoded from a variety of different sound sources. However, simply
increasing or decreasing the loudness levels of these MP3s does nothing
to ensure that as many of the frequencies present in the original WAVs
are saved from being filtered by the ATH-aspects of the MP3 lossy
compression method.
Yes. What's done is done. From there, only manipulating playback
options will have any effect.
6) The curve table which visually depicts the Absolute Threshold of
Hearing for frequencies ranging 20-20,000Hz is fixed (i.e. Absolute) in
relation to digital Full Scale - although this is still in dispute by
another contributor to this thread.
Myke
I learned a great deal more than you then, and I appreciate the motivation
you provided me to research MP3 things with more intensity than before.
