Classification results for six call types.

Call type	N_total	N_{correct classified}
22 kHz	18	17 (94.4%)
50 kHz trills	18	14 (77.8%)
50 kHz flat calls	18	12 (66.6%)
50 kHz complex calls	12	12 (100%)
50 kHz upward calls	12	8 (66.6%)
50 kHz composite calls	18	17 (94.4%)

Three call types (22 kHz calls; 50 kHz trills, 50 kHz flat calls) were available from six rats, three calls from each animal; 50 kHz complex calls and 50 kHz composite calls were available from five rats, and 50 kHz upward calls were available only from four rats. N, sample size for each call type and number of correctly classified calls.
