6.1 Preparation
There are many ways of reproducing the sound of records on a computer; the
following example only describes the basic procedure for doing this.

The signal received from the record player's magnetic sampling system cannot
be directly fed into the soundcard's line-in input, as the signal is frequency-
distorted for technical reasons. A so-called 'frequency corrector preamplifier'
between the sampling system and the soundcard is needed in order to correct
the frequency response. This is most easily performed using the amplifier's
phono input.

In order to rerecord, you will need:
! a record player
! an amplifier
! a computer with a soundcard
! around 700 MB free memory
! cables to connect the individual components
Sometimes leakage pickups (humming) can arise when the soundcard is linked
to the amplifier. The humming is caused when two devices that have already
been grounded (earthed) are connected with one audio cable. A by-pass power
filter or transformer can solve the problem. Sometimes it is simply enough if the
devices are connected to different power sources.

1. Connect the record player to the amplifier.
2. Connect the amplifier to the soundcard.
3. Clean the record.
