Hey, I think I've seen this addressed in the past but now that I'm running into the problem, I'm not finding anything. I've got 21 wav files that are all pieces (in succession) of a single track. I want to encode them to a single mp3 file, or alternately join them into a single wav file before encoding. I'm sure there must be a utility that does this easily, but I've not found it in a few quick searches. Thanks to any help here, and apologies in advance if this is something that I should know, which it likely is...

Here's one I posted a while back. It was meant for making a CD image though so it only works with 44.1 kHz, 16 bit, stereo WAVs. Of course you can join them in Winamp also, by using the Disk Writer plugin with single file mode enabled, or any sound editor software.

Foobar2000?

SOX will do also.
But this is a command line tool, usage:
C:\> sox.exe Track1.wav Track2.wav Track3.wav SingleFile.wav

Thanks for the thoughts, all. Especially the obvious one of running them all through Winamp's (or foobar's) diskwriter plugin. That's where I'd seen "single file output" before. I ended up dealing with the mental block by burning the tracks to an audio cd, then using EAC to rip range. Oh well. I'm glad to know about SOX, too.

WavMerge, available in this thread, is full-featured and non-time-limited, uncrippled shareware that gets the job done.

If you use Converter in foobar 0.9b6+ then you can even write a cuesheet at the same time - so you can still jump to the various parts quickly and easily (in foobar, or Winamp with the mp3cue plugin).

My CueMake will also join WAVE files and create an accompanying cuesheet (using placholder mapping of the filenames to populate cuesheet meta data). Obviously foobar has the benefit of (among other things) being able to go straight from n WAVEs to 1 MP3, rather than n WAVEs to 1 WAVE to 1 MP3.
