	Abstract = {Separation of underdetermined audio mixtures is often performed in the
Time-Frequency (TF) domain by masking each TF element according to the
amount of target energy it is deemed to contain. This work uses sigmoidal
functions to map the proportion of target energy to mask values. The series
of sigmoidal functions used encompasses the ratio mask and an approximation
of the binary mask. Mixtures are chosen to represent a range of different
amounts of TF overlap, then separated and evaluated using objective
measures. PEASS results show improved interferer suppression and artifact
scores can be achieved using softer masking than that applied by binary or
ratio masks. This improves the overall perceptual score of the separated
audio.},
