Benchmarking flexible adaptive time-frequency transforms for underdetermined audio source separation
14 years 2 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-...
