Sampling for those who don't know by now is the
conversion of analogue sound into a digital format that
is to say for those who remember cassettes and tape recorders,
sound on a tape, is stored as electromagnetic information
as a continuous strip which is picked up as it passes a coil
of wire (the Playback head) and boosted to an audible level
through an amplifier. Sampling effectively cuts the sound strip
up into thousands of small sections almost like cutting the
strip of tape into a thousand or more pieces and then converts
each section into a number, over a one second period,
anything from a few thousand to usually 44100 (44.1 kHz )
sections (or samples) a second is common for CD quality.
Studios can operate at 48 kHz or more for initial
recordings for higher quality capture of sound, converting
down to 44.1 kHz when eventually mastering onto CD.
From personal experience, I could tell the difference between
44.1kHz and 48kHz when recording and playing back, but at
48kHz, nobody could tell the difference between someone
talking live and the same voice being played back after
Can anyone remember that phrase Is it live, or is it Memorex?
Well I was caught out many a time thinking a voice recorded
was singing or talking live and vise versa.
These days Sampling usually means copying a drum loop
or piece of music from someone else's music, or using a sound
such as a bowed string, capturing a small snippet of it and then
looping the sound so it is a continuous note when played back,
then using a master keyboard, triggering the sound to play and/or
pitching up or down the sound to make different notes and
harmonies by playing 2 or more notes (triggers) at the same time.
