It is always interesting to learn how many different types of people are drawn to exploring the secrets that DMT and most other psychedelic's hold. Truly all walks of life!!

I'm also really happy to learn that so many actual scientists are frequenting this board, gives it a bit more validity in my mind.

Then again, I guess some folks are just gettin' fucked up, man

As far as me, I own & operate a commercial CD mastering studio, doing mostly stereo audio CDs.  I'm the guy that takes all the songs a band recorded and polishes them up to make them sound as good as they can on all different types of speakers.  I level out the overall loudness of all the tracks in reference to each other and bring them up to a standard loudness level. Then edit the fade-ins/fade-outs, spaces between tracks or crossfades etc... that make all the songs playback like a record, instead of just a bunch of songs on a CD.  After thats completed and approved by the client, I write the master disc and run error tests, to verify its bit integrity & quality before sending it to the duplication plant. Occasionally I also have do noise reduction and/or restoration type work like transferring an old record album to CD or reducing background noise from a security recording etc...

Mastering is the final step in music production (or whatever) that makes the product sound "professional". 

I also work as a freelance recording/mixing engineer at a number of local studios.

And believe it or not, I also teach Recording-I and Digital Audio-I & II at a local collage. 

Yes, I am the one teaching your children, MUAHA HA HA HA HA....(evil laugh)

Cheers,
