Benchmarking flexible adaptive time-frequency transforms for underdetermined audio source separation
2009 IEEE International Conference on Acoustics, Speech and Signal Processing
We have implemented several fast and flexible adaptive lapped orthogonal transform (LOT) schemes for underdetermined audio source separation. This is generally addressed by time-frequency masking, requiring the sources to be disjoint in the time-frequency domain. We have already shown that disjointness can be increased via adaptive dyadic LOTs. By taking inspiration from the windowing schemes used in many audio coding frameworks, we improve on earlier results in two ways. Firstly, we considerdoi:10.1109/icassp.2009.4959514 dblp:conf/icassp/NesbitVP09 fatcat:37edbsy37rccrjvrmejdlnvrgi
