!! Introduction
In recent years, many recording devices such as voice recorders, smart phones, tablet-type mobile devices, laptop PCs, etc, can be available in our surrounding environment easily, and exploiting them for array signal processing is one of the attractive scenarios. However, in most cases, recorded signals with different devices are not synchronous, which include unknown time offsets of recording start or sampling frequency mismatch. The aim of this task to evaluate source separation on such asynchronous channles.

The developement data consist of 66 stereo WAV audio files and 6 Matlab MAT files, which can be imported in Matlab using the commands load and wavread respectively. These files are named as follows:

!! Evaluation criteria
- We plan to use the criteria defined in the BSS_EVAL toolbox. The submitted results will be evaluated with SDR, SIR, SAR, ISR, using original sources at the first channel as "i" in bss_eval_images_nosort.m.
