It appears that "lame" doesn't support the IMA ADPCM format.
Instead of first converting to OGG and then to MP3 (which will produce
a poor quality result), you can use SoX to convert the WAVE file to a
new WAVE format that "lame" supports:
$ file test.wav
test.wav: RIFF (little-endian) data, WAVE audio, IMA ADPCM, mono 8000 Hz
$ sox test.wav -s test2.wav
$ file test2.wav
test2.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit,
mono 8000 Hz
$ lame test2.wav test.mp3
