Types of Equalizations

In my short experience, with audio and hifi, these are the Types of Equalizations I've noticed.

1. Source - Done at source mixing studio with dynamic range compression or other eq.
2. During encoding - If lossy encoding takes place. - Software equalization.
3. Soundcard DAC - Hardware equalization.
4. DSP - Hardware or software equalization. If you enabled it.
5. Amplifier - Hardware equalization.
6 Speakers - Hardware equalization.
7. Room - Hardware equalization.
8. Ear - Physical and biological equalization.
9. HRTF - Head related transfer function. - Crudely, how our brains listens.

From the above, the end user can tweak or modify the chain from 3-7.

All the best with your tweakings...

Pentax K-30 - YouTube reviews and impressions

Pentax K-30. Photo taken with a Samsung Captivate Glide
Got myself a Pentax K-30 dslr with a 18-55mm f/3.5-5.6 AL weather resistant (wr) zoom lens. Romeo over at Salam Stores Wafi, Dubai was a big help and I got a pretty good deal, near US Amazon prices with a WR lens (happy face).
Still learning the ins and out. Since there is not much posted about Pentax. Here's a collection of reviews and impressions I found on YouTube. I made a playlist of some interesting ones I found. This should help people decide if they want to go for this awesome camera :D

FiiO E11 Portable Headphone Amplifier With Micca Accessory Pack - Review

Micca Distributor - 5/5
Seller shipped very promptly and I received the package a day before the start of the estimated delivery dates. 


Package was shipped via USPS in a bubble wrap soft package. I would've preferred a similar sized small hard cardboard box instead for better protection.


I really appreciate the 100mAh bigger extra battery and universal (battery) charger by Scud. It's very thoughtful, useful and economical at this price.


Scud Universal Charger SFC-519 - 4/5
The charger has a NEMA 1-15 electrical plug, if you're outside the United States, you might need an adapter for sockets. Build quality is above average and the charger can be technically used to charge batteries of various mAh types. The charger's apple logo lights up when a battery is connected and starts blinking rainbow colors while charging.

It's too soon to comment on this battery's longevity. I haven't had any issues afte…

beyerdynamic DTX 101 iE - Mini-Review

I recently bought the beyerdynamic DT 770 PRO 80 Ohm headphones, and they're worth it. beyerdynamic being so well respected, I went for their DTX 101 iE Earphones, they look great, feel fantastic, no comfort issues. But In my opinion they sound terrible. My 15+ year old Aiwa Sound GT earphones sound better.

FYI they also hiss badly with my portable headphone amp (FiiO E11). These are low impedance headphones, so an amp is not required at all.

They sound dull, flat and lifeless.

Online shopping experiences

I recently got my first credit card and started shopping online, perhaps my experiences will encourage others to have a safe and fun shopping experience.

Being outside the United States, United Kingdom or Canada. There are few to none, quality shopping choices. Situation is worse in over-hyped Dubai, at least price wise, other side of the ugly coin is the UAE gets the worse spec'd products.

What's the alternative?
Well ShopandShip.com is the best option at the moment, they give you US, UK and a Chinese shipping address.

Do UAE retailers not care?
Most I think are complacently enjoying their eroding pseudo monopolies, thinking they control channels of distribution and price. That won't last long.

Others are greedy, like the big distributors in the region, I won't name names, because of the ridiculous liable laws in the UAE, which favor big business, employers and curb freedom of speech considerably.

What do I need?
1. Credit card.
2. PayPal (eBay owned), Amazon Payments, Google …

Opera - 10 years of usage insights

I've been using Opera as my primary browser since the year 2000, so I think it gives me some insight on areas of improvement.

Improvements
1. Downloads acceleration, backend work mostly. Focus on speed should be universal.
2. Status bar like Chrome, indicating uploads percentages. keep it optional of course.
3. Add some kind of animated icon while clearing private data. The entire interface freezes and Windows reports it as not responding during the cache flush process.

Feature requests
1. IRC - Auto update to themes like skins and promoted via My Opera.
2. Auto updates for skins.
3. Auto Nightlies and Beta channel updates.
4. Publicly transparent bug tracking and feature request handling system.
5. One click profile backup for bookmarks, toolbars, keyboard shorcuts and related files.
6. Global sync: Bookmarks, Toolbars, settings, Content blocker list, Cookie whitelist, every conceivable user customizable feature.
7. Add Zoom to 'Edit site' preferences.
8. One click settings backup.

LG Flatron W2261VP short term review

Bought my first LCD monitor after my CRT died (Yes CRTs still rule!). Since I've been using it only a few days, here are my short term observations.

Pros
1. Very reasonable price for a 21.5" size, 16:9, 1920x1080 resolution HD LCD monitor. Sine it's such a high resolution monitor, would suggest adjusting for text clarity using ClearType tuner. To avoid eye strain.
2. D-SUB (Analog VGA), DVI-D, HDMI, 3.5mm headphone jack.
3. The 'www' 'f Engine' preset is pretty good for text readers like me.
4. Matt screen surface. No silly reflections.

Cons
1. No 1:1 pixel mapping option. Really matters if you prefer running at lower resolutions, but don't want to scale.
2. No height adjustment. Not a big deal in my case.
3. Lack of on-screen soft keys (like Samsung monitors) makes the side buttons difficult to use. This gets very annoying.
4. Viewing angles are not good at all, but manageable.
5. No VESA mounting interface. Don't need that for the moment.

Odd quirk
The moni…
