This is how I, when I suddenly needed it, easily found out how to
transfer music from lp to mp3. This is quick'n'dirty. I should buy better
cables and work with noise reduction. If I ever get around to that I
might update this page.

Hardware setup
You need:
- Laptop with at least one sound input and one sound output.
Microphone in and headphones out is what I have on my Eee and that is
good enough.
- Stereo with preferably volume regulated head phones output.
- Jack to minijack sound cable
- Headphones

Software

Howto
- Connect your amplifier and your laptop with the jack to minijack.
- Connect your headphones to the laptop and put them on.
- Start the record.
- Make sure you get sound through - make sure the microphone input is
enabled in the volume control settings.
- Set the headphone output on the amplifier to a sensible volume. Not
too high or you will get overdrive.
- Start audacity.
- Start the record again near the start of the song you want to record.
- Click the red "record" button in audacity when the song is about to
start.
- Keep an eye on the volume meter in the top and the blue signal in
the main part of the window to see if you get overdrive.
-
-
There are slides to regulate recording volume but it is better to
regulate the input level before it leaves the stereo if possible.
- When the recording is done click the yellow "stop" button.
- If you started the recording too early or ended it too late you can
make a selection of part of the track. I cannot figure out how to do it
right so I click the beginning, notice the number of seconds it says,
click the end (now both the start and end time changes into the end
time), and manually enter f.ex. 00.00.07 as the start time.
- Select File -> Export Selection and save as Wav file. There is an
mp3 option but the mp3s I get are not very standard. They don't work
with mpg321 or mp3cut. So save as wav.
- Open the wav file in audacity and check if it sounds good enough or
if you want to redo it.
-
- When happy with wav file, bladeenc it:
bladeenc -256 file.wav
Audacity can do some noise reduction, I haven't played with that. You
might also want a better soundcard than the one I am using... but I get
rather good results all things considered. I think my cable is the
weakest link.
