* Axient 28kHz
* Sennheiser 32.768kHz
* Sennheiser 32.000kHz
* Sony 32.382kHz

Sounds should be 8-bit unsigned mono .wav files between 24000 and 48000 Hz. This can be done in Audacity by first making sure the track is Mono by going to Tracks>Mix>Mix Stereo Down to Mono and then choose "Other Uncompressed Files" in the export dialog and set Header to "WAV (Microsoft)" and Encoding to "Unsigned 8-bit PCM".
