It also assumes a speaker's reactance is purely resistive. It's not.

For really bad audio, no. For otherwise perfectly fine audio, yes.

Dynamic audio power limiting introduces a whole host of audio distortions that would cause your computer to lie to you by not playing what you told it to. Your computer lying to you is a problem in principal I think, but specifically if you

It's hard to know. Speakers are insanely complex beasts whose electrical reactance changes depending on the signal. To simplify things we use measures like RMS current ratings for amplifiers because if you put a sine wave through a spe

If you do, I highly recommend The Computer Music Tutorial[0]. It's an older book but provides an excellent overview of how digital audio works. [0] http://www.amazon.com/gp/product/0262680823

It's more complex than that. Let me explain: Audio is typically passed into a soundcard's digital audio converter (DAC) as integers representing samples of the audio waveform. For example, a full volume sine wave looks something

Agreed in principal, however all the ways that could prevent rogue userland software from playing damaging audio (eg. using a limiter of some sort) would either distort or introduce quite a bit of delay to otherwise perfectly safe audio pla

> But this is exactly the same if you put your mp3 file through Audacity and increase it and play with WMP, or if you put a DirectShow filter that amplifies the volume after your codec output. Indeed, and doing that destroys audio equipm

Likely not an mp3 because most of the super high frequencies that result from digital clipping wouldn't be encoded in an mp3. Most encoders do a low pass filter as their first step (getting rid of most of the problem) and then smooth o

There's more to optimization than setting -O3. Learning how various compilers behave and how their optimization features interact with your code are valuable skills and may well have been within the scope of the course. Certainly worth

Which is bad, because without registering an agent, you have NO safe harbor protection.

The key here is Cisco is paying the patent royalties for anyone who uses their codec binaries - which will cost them $6.5m/year. They could do the same for x264, but it's probably legally safer to distribute an implementation they

For WebRTC they also need an encoder. ffmpeg uses libx264 for encoding H.264, which is GPL.

Much of the point of using something like Hadoop is to increase raw disk IO by parallelizing it over many machines. So no, it's not a terribly valid benchmark.

Someone should probably point out: most of your problems were related to doing full business validation from a crappy provider. Business validation is optional and doesn't enhance the transport-layer security benefits of using SSL.

I was rooting for #10 as well. The selected logo looks... cheap. When you can see the bevels they're distracting, but at typical resolutions (as on the home page) they get anti-aliased out leaving the edges of the letters looking fuzzy
