   Very easy. Just about any sound editing tool will allow you to record
   from your sound card's line-in. However, there's a program specifically
   designed for what you're trying to do: gramofile.

   Or, if you're running Debian, "apt-get install gramofile". :)

   Also, I have to say, if you're really planning to dump your LPs and
   tapes, you might want to make lossless archives of the music (or, at
   least, the more valuable, less easily replaceable bits) compressed with
   FLAC instead of ogg or mp3. Make oggs too, for playing, but keep
   archives of the FLAC files on CDR or other backup medium. Then, if you
   ever want to transcode to a newer or better format, you'll still have
   the pristine originals around.

   Since you didn't have much luck with picking something to _record_
   sound files, I tried a Google search on "capture sound Linux".

   First of all, it appears that MP3 encoding utilities like BladeEnc
   accept stdin, so you should be able to read directly from a sound
   device file, as specified on the command line. That seems like the most
   straight-forward way, off the top of my head.

   There's also a sound-capture client for the relatively obscure sound
   server named JACK (or JACKit), detailed here:
   [3]http://desktops.linux.com/desktops/04/08/09/1513255.shtml?tid=25

   This thread...
   [4]http://www.linuxquestions.org/questions/history/261684
   ...suggests you should be able to use KRecord or audicity directly for
   the purpose you have in mind. Consensus seems to favour audicity.

   This article...
   [5]http://www.newsforge.com/article.pl?sid=04/10/20/1423245
   ...says to use something called "ecasound" to do the capture from
   /dev/dsp, and then audicity to clean it up (if necessary).

   There's a Freshmeat category with a mere 130 entries in it:

   'Hope that helps. (I'd not gotten around to considering this problem
   before.)

   A quick run down the list of people's suggestions:

   1/ I was unaware that general-purpose audio file editors like audacity
   can record line-in. It certainly seems to contradict the "one job well"
   maxim, but I guess we've come a long way (toward hell, that is).

   Had I known, I probably wouldn't even have posted, because it's the
   record (or capture) part that I was missing. Thanks for pointing out
   that it's worth saving to a lossless format, though.

   2/ vsound is for recording audio output of programs, and thus isn't
   applicable to my situation.

   3/ ecasound seems like exactly what I am looking for. It even has an
   Emacs interface :-)

   4/ gramophile can detect and cut tracks, but I really hate its
   half-arsed curses UI. (It doesn't even react to screen size change.) It
   would have been much better off with a straight CLI like ecasound.

   Well, actually, you can record using nothing but cat(1). What you can't
   do (at least not easily) with cat is set the sample rate and the
   mixer/channel-select controls. Once you've got something that can do
   controlled playback of raw sound data, though, you're about 95% of the
   way to making something that can record as well, So, while in general I
   agree with you about the bloat issue, in this case I think it makes
   sense to provide the extra feature.

   The Linux sound card interface is dead easy once you look into it.

   I've actually edited raw sound files in emacs. There's even a live
   concert recording up on the Internet Archive now that has emacs in its
   lineage, thanks to your truly. :)

   Uncompressed sound file formats are dead easy once you look into it.

   Bummer. I've heard good things about it, but never actually tried it.
   The filters designed for clicks and pops (as often found on vinyl)
   seemed like a pretty useful feature too. Trapping SIGWINCH is not
   difficult. Did you send in a bug report?

   One last thing I should mention: if you ever plan to burn your sound
   files to audio CD, you should make sure the data is a proper multiple
   of the audio CD sector size, or you may end up with coasters. The
   "--sector-align" option for FLAC is a good place to start.

   It's true that cdrecord will pad the tracks if you tell it to, which
   will prevent you from creating coasters, and that's a good thing.
   However, it pads each track (or each track that needs it), which can
   cause an audible click or pop, as the sound level suddenly drops to
   zero and then leaps back up. This is especially noticable with live
   recordings. The FLAC "--sector-align" option actually borrows a few
   bytes of data from the next track to pad out the current track size,
   which ensures that there are no audible artifacts between tracks, which
   is why I recommend it.

   > sox works great for me for recording from line-in.

   Ah, I hadn't noticed that, but I'm certainly not surprised. Sox is an
   awesome and indispensible tool for anyone working with audio on Linux,
   IMO.
