Thanks to all those who mailed me.
Just to clarify what Im looking for:
1. Temporal Masking Functions in the last 6 years - These are forward and/or backward masking functions developed int he last few years. Usuually they are called spreading functions or temporal masking/spreading.
2. Im also looking for newish simultaneous masking functions. these are sometimes called frequency spreading functions/models.
If anyone has come across any new spreading functions for any types of temporal or simultaneous masking please let me know.
I am currently researing masking models - frequency spreading functions and time domain spreading functions (forward and backward masking).
I am looking for any new publications etc containing new masking models. These would be publications in the last 5 years or so that have introduced new masking models or new spreading functions.
I have been looking at the Frequency Spreading and Time Domain Spreading functions used in PESQ and PEAQ but I would like to find new models introduced since PESQ and PEAQ were standardized. In other words I want new masking models that have been developed in the past 5 years.
Also, I would be interested in any summary papers or comparison studies that have covered a number of speech or audio masking models.
I would be most grateful if anyone could help me out with information.
