First Wave Of New Audio Interfaces

Gotta love technology. M-Audio has introduced a new USB2 audio/midi interface. 4 really excellent microphone preamps, and DSP (for near zero latency mixes/monitoring). List price, $450, but the street price is quite a bit less.

UPDATE 11/28 by E: After checking the Mic preamp specs, and that of the Project Mix I/O, the Mic preamps on this new box are a lot better. After doing some recordings with the Project Mix I/O at 96Khz, I thought the preamps were amazing……..so this little box might be capable of some even more amazing recordings.

MP3 Compression Explained

Found a very interesting article about how MP3 compression came about. It is, at times, rather techie, but very interesting none the less.

But what is MP3? The usual explanations usually take one of two forms. The long version, available in technical papers, is written in jargon and filled with math. The short version, often used by newspapers and nontechnical periodicals, simply states that the process eliminates parts of sound not normally heard by the human ear. But this one-sentence description raises more questions than it answers for any reasonably tech-savvy reader: how does it find those unheard sounds, and how does it get rid of them? What’s the difference between the different bit rates and quality levels? If you’re anything like me, you’ve often wanted to know the mechanics of MP3, but not to the point of writing your own encoder.
