Dither noise in audio recording… in “today’s” reality.

There are lots of guys out there that swear by recording audio only at 44.1khz citing that recording at anything higher introduces quatization errors when down converted for CD-Audio formats  and require “dither noise” to compensate for.

Wikipedia, has some interesting articles that explain how quantizing your audio can add bad resonant frequencies to your audio and emphasizes how dither noise can solve this problem.  I’m not going to explain them again here, but, what I WILL do is point out what these examples are NOT. It is important to note that the examples are *intentionally modified* from real-world scenarios so as to explain what quantization errors are and how adding noise (dither noise) to a recording can be used to reduce the harmonic errors introduced from (poor) sample rate conversion.

BitCoin is not GOLD, and It’s value will decrease to pennies on the dollar within a decade.

BitCoin has been getting a lot of buzz in the media recently.  The people who love BitCoin are proclaiming it to be the currency of the future and love to point out that the US Dollar has dropped 90% against the BitCoin in recent months.  BitCoin has gained much media buzz due to the notable support of the Winklevoss brothers who are famous of suing Mark Zuckerberg for allegedly stealing their idea for “The Facebook” (which they called “Harvard Connection” and then “ConnectU”) Continue reading “BitCoin is not GOLD, and It’s value will decrease to pennies on the dollar within a decade.”

Steve Jobs, please return from the dead and give me back my Home and End Keys!

I’m a coder.  I code.  Coding involves a a lot of typing.  Coders are known to be stubborn when it comes to switching away from editors that they’ve grown accustomed to.  Ask a dozen developers what their favorite editor is and you’ll find at least 1 or 2 that still love the hell out of “vi”, an old-school, but definitely archaic, editor which, for whatever reason, they find still useful today.  VI was designed for a time when computers didn’t have arrow keys so you can’t even cursor through your documents without doing some wonky key combination involving some control keys.  I don’t use “vi” so I’m not the best person to speak of its history, but if you’re curious I’m sure there are plenty of fan pages out there dedicated to it.

RFC4695 – “RTP MIDI”: A Protocol Not Fit for Consumption.

I have a pleasure of working for an eccentric start-up that deals with music applications and devices.  A requirement of a couple of projects I’m working on are that they be able to send MIDI data (Musical Instrument Digital Interface) wirelessly to a Mac, iPAD, or iPhone.

There are lots of ways to do this and a few different open standards out there.   Of all the protocols available Apple chose RTP-MIDI as its standard for wireless MIDI communication between iPADs, iPhones, and Mac computers.

Delphi XE5 Thoughts: Contemplative

Just got my hands on Delphi XE5.  I know that, although the crew at Embarcadero probably broke out the wine and cheese to celebrate the release of their first Android-capable IDE and Compiler, and certainly what they’ve accomplished is a feat no other company, with the exception of Unity3D, has accomplished; I can’t help but imagine that there are some engineers and testers over there that are not feeling too happy right now.

I decided to switch to WordPress

After LifeType severely failed me.  I switched to word press.  let’s hope that this site doesn’t get attacked with all the spam attacks that LifeType seemed completely incapable of stopping.  Ultimately I lost about 50 articles.   I’ll be reposting some of the more relvant ones here soon.
