!! 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 data has two different recording environments:

*__300ms__: all the microphone elements are spaced in a radial fashion. The spacing of each stereo microphone pair is about 7.65 cm. The reverbaration time is about 300 ms.

* ''dev_src_<src>.wav'': single-channel speech signal, shared in whole the development data. @@ -Lines: 27-31 changed to +Lines: 30-34 @@
* ''dev_<srcset>_<cond>_src_<src>.wav'': MAT file including the variable A of the room impulse responses, whose size is [[number of the channels, number of the sources, number of samples]. Note that the recording time offset is included in the impulse responses.

!! 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.
