Most demo users should be able to use Audacity for recording monophonic 16,000 sample/second, 16-bit sample audio into .wav files for upload.

Here are instructions for Microsoft Windows users which may be simpler than downloading and using Audacity:

  1. Select Start / Programs / Accessories / Entertainment / Sound Recorder (or Start / Run... sndrec32.exe — note: you must have use of a Microsoft Windows XP license to download the linked copy.);
  2. Choose "Properties" from the File menu;
  3. Click Format Conversion / [Convert Now];
  4. Choose PCM Format Attributes: 16.000 kHz, 16 Bit, Mono (31 kb/sec);
  5. Click the [OK] button on both dialog boxes;
  6. Record the selected phrase with the red circle (record) and black square (stop) buttons;
  7. (optionally) play to verify that the recording is what you want; and
  8. Choose "Save As..." from the File menu to save the file.
Alternatively, you may download this empty rec.wav file to your desktop and right-click on it, selecting "Record" from the pop-up menu to change it; remember to save it after recording.
