F7 Sound and Vision's Michael Oster has been recording the sounds around him since the 1970s, beginning on cassette and continuing all the way up to include 24 bit portable laptop based systems....
Diary of a Recorded Sound
Ever wonder what happens during the life of a recorded sound?
Something triggers the movement of molecules which causes small changes air pressure (within a certain frequency range and amplitude range, we can hear those changes and call it sound).
Changes in air pressure impact the diaphragm of a microphone (a transducer) which alters a magnetic field set up inside the mic. The diaphragm moves in relation to those changes in air pressure.
Changes in the magnetic field result in the generation of small amounts of electricity.
In some microphones, the electricity is amplified before leaving.
The electricity is sent from the microphone to a preamplifier.
The preamplifier brings up the levels of the electricity to a point that they become useable and can be recorded.
From the preamplifier, the signal is sent to digital converters where the electricity is sampled and changed over to data which approximates the frequency and amplitude of the prior signal.
The data is then sent to a computer or digital recorder where just about anything is possible. The data can be manipulated and stored or converted to many different data formats such as WAV, mp3, mp2, AAC, images, or whatever.
For playback, the data is sent to another set of converters and is changed back to electricity (digital to analog conversion).
That electricity goes into an amplifier then to speakers or headphones.
Speakers and headphones (transducers) trigger the movement of molecules which cause small (and sometimes not so small) changes in air pressure (within a certain frequency range and amplitude range, we hear those changes and call it sound).
OK, I know a few "tweakheads" are going to say that I left out things like filters, effects, analog recorders, or other stuff. They're right, but I wanted to list out in pretty basic terms what happens when a sound is digitally recorded (as most are these days) and played back.

Record a Fart
Put the microphone where? Here's a few points to consider before documenting that gas discharge...
The Story Behind My CDs
Personality, character, style, emotion and more go in before a CD ever comes out. There's a method to this madness.
Before you trash your old microphone and buy a new one. try something simple and unleash the multiple personalities of the mic you already have...
It's not the gear.
It's how you use it. Skill counts big in recording...
