Digital recording of sound and signals?

Describe one method for the digital recording of sound. Address the following issues (at least): Given an actual pressure wave in a gas, how do you translate the wave into a signal that can be digitized. What does it mean to digitize a
signal?

First point...how to translate a pressure wave into a signal. This is where the transducer comes in, in the simple case you could use a magnet suspended through a coil with a flat piece of paper to "catch" the sound waves (like a speaker).

, Which won CAS and IFTA nominations for Best Sound. At the start of season two, Hill invested in a Sound Devices 788T-SSD, which became his main recorder on the cart, with the 744T used as a cart-based, two-channel backup. His original 788T became his dedicated portable run-and-gun recorder and is fitted with a Sound Devices CL-8 mixing controller. It is always on stand-by for when Hill is on-location.

 

 Hill’s rig consists of Sennheiser MKH 60s and an MKH 70 outside and mostly MKH 50s for interiors. The show, primarily shot in Northern Ireland, takes place in a lot of remote and hard-to-reach locations. Through his tenure on the series, Hill has encountered all environmental conditions; including extreme cold in season one and a hurricane in season two. On many of these on-location shoots he relies on Audio Ltd. radio mics and DPA 4071 lavalier mics to provide isolation from the environmental conditions. Hill also uses Audio Ltd. 2040 radio mics with an RK6 (six-channel radio rack) on his cart and one or two RK3s (three-channel radio racks) in his portable setup, so he can quickly go from cart to portable.

Dusk in Autumn: What happened to personal sound recording?

by agnostic

We keep hearing about how creative and do-it-yourself people have become, especially young people, since digital age began. That's clearly not true -- just look around and see what the result has been, compared to what young people were up to in the late '50s through the early '90s. They invented a hell of a lot more with less dazzling technology. Obviously it's the qualities of the person, and most importantly of the zeitgeist that influences them, rather than of the technology the person employs that determines whether the outcome is good or bad. Therefore, huge technological change will have almost no effect one way or the other on the quality of the little things that people create. If it were otherwise, you would be able to classify things you'd never seen or heard before with high accuracy into the pre-digital and post-digital periods, as long as you stripped away other giveaway clues. In reality, the terrible-sounding single-focused music of the post-mp3 era doesn't sound so different...
