Presented at the 8^th international symposium on Computer Music Modeling and Retrieval (CMMR 2011), Bhubaneswar, India, March 2011.

Sound examples

Example 1 (x₁(t)): Sum of two Gaussians with frequency shift (ΔF) of +4 ERB units and time shift (ΔT) of 10 ms. Masker SPL (L_M) = 80 dB, target SPL (L_T) = 50 dB; target is not masked.

Input of the irrelevance time-scale filter

Output of the filter

Example 2 (x₂(t)): Sum of two Gaussians with ΔF = -2 ERB units and ΔT = 5 ms. L_M = 80 dB, L_T = 15 dB; target is masked.

Example 3 (x₃(t)): Musical sound. Clarinet playing the note A3.
