In order to cancel the noise introduced by the ambiance simulation, an adaptive filter based noise cancellation algorithm was applied to the recordings of the SPID corpus. Furthermore, a frequency-domain noise and cross-talk suppression was applied. The two time and time-frequency pots below show examples. The enhanced as well as the original signals are available for the entire corpus parts where the ambiance simualtion was used.
