   * sox
      * 'rec -c 2 -r 44100 -s w $filename'
      * (record 2 channels at the rate of 44100, size = w <wide?>)
   * mhwaveedit

==============================================

If you want to record from tape, you can connect your deck directly to the computer.  Connect the deck's "line-out" RCA jacks to your computer's "line in" jack.

If you have a standalone turntable, you cannot record directly to your computer.  You have to connect it to an amplifier or receiver with a "phono" or turntable input, or to a phono pre-amplifier and then record from the amplifier's "line out" or "tape out" jacks.  USB turntables can be plugged directly into your soundcard jack.

Our primary goal is to get down a listenable copy of a vinyl record without losing significant information.  We are making a realistic trade-off between time spent recording and sound quality, between noise reduction and loss of data.  After all in most cases a new cd costs less than $10.00.

---++ Setting up Audacity:

   1 Go to the Audio I/O tab of Preferences and set both the playback and recording devices explicitly to your inbuilt sound or to the computer sound device your cable is plugged into. 
   1 Change the recording channels on the same Audio I/O tab to "2 (stereo)".
   1 Select line-in as the recording source on Audacity's Mixer Toolbar dropdown input selector:
   1 Set software playthrough to monitor the recording.
   1 Set the volume level of your recording input to avoid clipping.

---++ Record and Modify
   1 Record either with Audacity ( red record button ) or sox
   1 Save as either .aup or .wav
   1 Modify:
      * Amplify
      * Remove noise
      * Remove clicks
      * Enhance???
      * Break into tracks   

---++ Write to CD:
   * K3b
   * XCDRoast
   * ?
