LAME 64bits version 3.100 (http://lame.sf.net)
usage: lame [options] <infile> [outfile]
<infile> and/or <outfile> can be "-", which means stdin/stdout.
RECOMMENDED:
lame -V2 input.wav output.mp3
OPTIONS:
-b bitrate set the bitrate, default 128 kbps
-h higher quality, but a little slower.
-f fast mode (lower quality)
-V n quality setting for VBR. default n=4
0=high quality,bigger files. 9.999=smaller files
--preset type type must be "medium", "standard", "extreme", "insane",
or a value for an average desired bitrate and depending
on the value specified, appropriate quality
settings will
be used.
"--preset help" gives more info on these

Hm, what created such wav file? Because that adpcm variant should have
0x0017 twocc and not 0x1700 one.

Looking at your output it looks like it can't figure out what

increasing the value for 'analyzeduration'?
If you know the details you could manually specify them,
something
like:
ffmpeg -acodec pcm_s16le -i input.wav out.mp3 (it's likely going
to
be
pcm_s16le or pcm_s24le or pcm_s32le)
Perhaps you don't have these codec installed/enabled. You will
want
something with PCM in it. Run: ffmpeg -codecs and look for
anything
with
PCM in it. On Linux, and possibly Mac, you could run: ffmpeg
-codecs
|
grep
-e '\sPCM'
to filter for lines containing PCM for you.
