Well, I've been working hard (off and on when I've had the chance) these past 7 days on what's turned into another major project!
After creating the two new sets of EQ presets (with the adjustment in my last post) to go with the +12 dB bass boost feature in Rockbox, I realized I need to completely reorganize everything, and get rid of everything
except what you've known as the "Optimized" and "OptimizedLite" categories. I'm also in the process of completely overhauling the first set of presets named "EQ presets" (i.e., "EQ presets 1.") Originally, that set was designed to work with the bass boost switch on the FiiO E12A amp. But I quit using that in April of this year after getting a more-powerful Cayin C5 amp. So therefore, I've now decided to make this regular set of EQ presets sound best
without using any physical bass boost switch on any external amp!
Basically, I'll be taking my new, beloved, overhauled "Cayin C5" presets that I'll be happily using, and recreating a separate, new "first set" by modifying the "Cayin C5" ones with the following adjustment:
64 Hz: +2.5 dB
125 Hz: +2.0 dB
250 Hz: +1.0 dB
500 Hz: +0.3 dB
(You can just use a higher bass increment in the EQ presets to make up the difference if you don't have an external, physical bass boost switch, and it'll sound good.)
So anyway, there will still be just two sets of EQ presets: one for use without a physical external bass boost switch, and one for combining with the bass switch on the Cayin C5 amp.
Well, to make use of all the new fabulous possibilities with Rockbox's +12 dB bass feature, each set of presets will have the following midbass categories (each in its own folder):
Cool
Hot
Lite
Ultra Lite
Wicked
Z Flat
Cool is the old "OptimizedLite,"
Hot is the new "Optimized,"
Lite is the new "OptimizedLite,"
Ultra Lite is the new "OptimizedLite" with further-reduced midbass, and
Wicked is the old "Optimized."
Z Flat will just have a couple of very basic presets.
And as you should already know, each midbass category (except Z Flat) will have its own set of treble sub-categories, each in its own subfolder:
Additional Boosted Treble
Boosted Treble
Classic
Less Treble
Reduced Treble
Treble Out
Treble Way Out
(The
Additional Boosted Treble sub-category is new to the list, by the way.)
Anyway, these are sounding
absolutely spectacular! With this awesome +12 dB Rockbox bass feature, I can use lower bass increments in the EQ presets, and especially can use lighter midbass categories with better soundstage and less coloration that still pound hard and throb bigtime, which I sometimes couldn't do before. These presets are sounding a lot more solid with less background hiss noise and better dynamic range. I rarely need to use the 9th and 10th bass increments anymore (where the dynamic range is noticeably compressed and the background noise is the worst). And I also find myself using an extra volume precut on the EQ much less often.
After I've had a chance to re-organize everything and use it for several days, I'll post these newly-improved EQ presets here for you to download and relish. In the coming weeks, I'll eventually start a new topic thread with brand-new, detailed instructions, and with updated preset designations for those 12 songs. The thread will probably be entitled, "DiscoProJoe's Rockbox EQ Presets, Version 3.0."
Stay tuned, my friends! The future is sounding beautiful.
