Hi Wesley,
As others have pointed out, if you have a record player already then you
can hook it up to the audio input of your PC sound card and record the
sound that way.
Actually you are far better off with a preamp. IIRC levels
(impedance?) from turntables don't match well with line-in on a sound
card.
There are at least three factors to consider when hooking up a turntable
to a sound card:
* signal level -- some turntable cartridges give very low output,
often lower than microphone levels
* impedance -- some turntable cartridges have high output impedance,
which needs an amplifier or preamp of high input impedance
* equalisation -- records are recorded with high-frequencies boosted
and low frequencies cut; during playback, you need an RIAA
equalisation filter to correct this
Your best solution is as recommended: plug a turntable into a amplifier
with a 'phono' input and record using a sound-card connected to the
tape-recorder outputs.
You could try connecting a turntable output to a microphone input and
apply the equalisation in software after recording (Audacity has an RIAA
equalisation filter), but you would probably do better to use a real
hardware preamp to ensure that the levels and impedance are correct.
