Benchmarking flexible adaptive time-frequency transforms for underdetermined audio source separation
13 years 11 months ago
We have implemented several fast and flexible adaptive lapped orthogonal transform (LOT) schemes for underdetermined audio source separation. This is generally addressed by time-...
