[Android Software Development] They Drew First Blood:
Re: more cowbell

This is going to be a long post, sorry for that... I will try to explain what I have found the different adjustments within the mod affect. [MENTION=4454119]t1.8matt[/MENTION] TL;DR check out the settings marked below in red to jack up your bass. Did you try the first or second profile I posted- titled 4.3 (the first) or 4.2.2 (the second)- they are both fine on 4.2 by the way? The first one had way more bass enabled. These profiles I made for my in-ear-phones which have decent bass response, so it is very likely there is a big difference when on bluetooth/dock or whatever. To get more bass out of the mod, enable and mess around with these options specifically: (here is a repost of my first profile, with the bass adjustments marked in red)

V4A FX only:

1. Master Power: ✔

2. Playback Gain Control: ✔

- Select Effect Strength: Slight

- Max Gain: 6x

- Max Output: -3.0 dB

3. FIREqualizer: ✔

- Select Preset: Custom (based on Vocal Booster: left to right: -2.5 -1.7 -0.5 0.0 0.0 +0.5 +1.4 +3.5 +2.9 +2.5) <-- Adjust/boost the curve at 27Hz, 55Hz, and maybe 109Hz for more bass to your liking. Check out this great interactive chart concerning the frequency response curve.

4. Convolver: ✔

- Impulse Response: Apple iPod nano6-Default.irs

5. Field Surround: ✘

6. Differential Surround: ✘

7. Headphone Surround +: ✘

8. Reverberation: ✘

9. Dynamic System:✔

- Select Listening Device: Common Earphone (v2) <-- This selection gives the most additional bass among the other headphone choices

- Select Dynamic Bass: 3 Percent <-- Raise this for more bass, seems to affect low-low-end more, too much may make your bass muddy/boomy

- Tube Simulator(6N1J): ✘

10. Fidelity Control:✔

- Enable ViPER Bass: ✔

- Select Bass Mode: Natural Bass <--Gives more bass than "Pure Bass+"

- Select Bass Frequency: 80Hz <--Low-pass filter for bass boost, only bass below this frequency will be boosted- so the higher this setting, the wider the range of bass that will be boosted. Adjustable from 40 to 100Hz, I think most big bass hits in hip-hop will be below 40Hz but still sustain in the entire range below 100Hz, kick drum hits between 80-150Hz

- Select Bass Boost: 3.5 dB <-- Raise this for more bass

- Enable ViPER Clarity:✔

- Select Clarity Mode: XHiFi

- Select Clarity: 8.0dB

11. Auditory System Protection (Cure Tech+): ✔

- Select Binaural Level: Slight

12. Master Gate (Limiter)

- Output Gain: 2.3 dB

- Channel Pan: 0.5 : 0.5

- Limit Threshold: 0 dB

Option 1 self-explanatory.

Options 2 and 12 control the master volume levels.

Option 3 is the equalizer- adjust the frequency response curve at ten different intervals from bass to mid to high frequencies.

Option 4 will load IRS samples- these process the sound to a pre-defined response curve as a starting point for any other sound adjustments. Usually I will disable all other options before loading a new IRS sample, then refine that sound if necessary.

Options 5, 6, 7 I haven't really messed with but would affect the Surround effects. Same for 8 which would affect Reverb.

Option 9- the dynamic system seems to affect the low-end frequency more heavily (because it contains dynamic bass), but may affect the high-end too- maybe this feature is to give a more full response curve from 20-20000Hz or something...? Depending on which type of headphone is selected.

Option 10- most of my adjustments after loading an IRS will start here. This section is where the XHiFi mod has been rolled in. ViPER Bass affects the low end frequencies, ViPER Clarity affects the mid to high end frequencies.

Option 11- Seems to compress the sound a bit and give the stereo a tiny bit of differential...?

There you go, I guess this is a summary of what V4A is to me. It would be really nice if anyone had a link to somewhere that gave confirmed details for all these adjustments. I haven't looked too hard and assumed maybe I would have to Google translate one if it existed. There are so many different adjustments within the V4A mod that although it takes time, I do recommend to enable one adjustment at a time and fiddle with it to see how it affects the sound, then disable it and enable another and repeat the process, then start combining them. Sorry again for the huge post but I am hoping it is insightful.
