1. rules for naming files in the database
1-1. mixture files
./[DATA_TYPE]/[DATA_TYPE]_[NUMBER_OF_CHANNELS]_[NUMBER_OF_SOURCES]_[ENVIRONMENT_TYPE]_[LOCATION]_[SAMPLE]_[FILE_KIND].wav
where [DATA_TYPE] :== Dev || Test1 || Test2
      where Dev  : development dataset
    	    Test1: test dataset in which noise is recorded in exactly the same place as in the development dataset
	    Test2: test dataset in which noise is recorded in an environment which is of the same type as but different from in the development dataset
      [NUMBER_OF_CHANNELS] :== 2ch || 4ch
      where 2ch: 2 channels
      	    4ch: 4 channels
      [NUMBER_OF_SOURCES] :== 1src || 3src
      where 1src: 1 source
      	    3src: 3 sources
      [ENVIRONMENT_TYPE] :== Su || Ca || Sq
      where Su: subway
    	    Ca: cafeteria
	    Sq: square
      [LOCATION] :== Ce || Co, if [ENVIRONMENT_TYPE] == Ca || Sq
                 :== Ce,       if [ENVIRONMRNT_TYPE] == Su
      where Ce: center
      	    Co: corner
      [SAMPLE] := A || B
      [FILE_KIND] :== Mix
      where Mix: mixture
Notes: the number of channels of the mixture files is the same as [NUMBER_OF_CHANNELS]. For example, if [NUMBER_OF_CHANNELS] == 4, the corresponding mixture file is a 4 channel .wav file. The m-th channel of a mixture file contains the recording by the m-th microphone.

1-2. source image files and the noise files
./[DATA_TYPE]/[DATA_TYPE]_[NUMBER_OF_CHANNELS]_[NUMBER_OF_SOURCES]_[ENVIRONMENT_TYPE]_[LOCATION]_[SAMPLE]_[FILE_KIND].wav
where [FILE_KIND] :== SrcImg1 || SrcImg2 || SrcImg3 || Noise, if [NUMBER_OF_SOURCES] == 3
      	          :== SrcImg  || Noise,                       if [NUMBER_OF_SOURCES] == 1
      where SrcImg1: image of source 1
      	    SrcImg2: image of source 2
	    SrcImg3: image of source 3
	    SrcImg : image of the source (1 source case)
	    Noise  : noise
Notes: the other parameters are defined in the same manner as for the mixture file. The source image files and the noise files are not provided to participants except for the development dataset. The number of channels of these files is the same as [NUMBER_OF_CHANNELS]. The m-th channel of these files contains the recording by the m-th microphone.

1-3. monaural source files
./[DATA_TYPE]/[DATA_TYPE]_[NUMBER_OF_CHANNELS]_[NUMBER_OF_SOURCES]_[ENVIRONMENT_TYPE]_[LOCATION]_[SAMPLE]_[FILE_KIND].wav
where [FILE_KIND] :== Src1 || Src2 || Src3,  if [NUMBER_OF_SOURCES] == 3
      	          :== Src,                   if [NUMBER_OF_SOURCES] == 1
      where Src1: source 1
`	    Src2: source 2
	    Src3: source 3
	    Src : source (1 source case)
Notes: other parameters are defined in the same manner as for the mixture files. The monaural files are not provided to participants except for the development dataset.

1-4. DOA files
./[DATA_TYPE]/[DATA_TYPE]_[NUMBER_OF_CHANNELS]_[NUMBER_OF_SOURCES]_[ENVIRONMENT_TYPE]_[LOCATION]_[SAMPLE]_[FILE_KIND].txt
where [FILE_KIND] :== DOA
Note: the other parameters are defined in the same manner as for the mixture files. The source DOAs are written in this file in the following way:
(3 source case)
[DOA1] [DOA2] [DOA3]
[EOF]
(1 source case)
[DOA]
[EOF]
where [DOA1]: DOA of source 1
      [DOA2]: DOA of source 2
      [DOA3]: DOA of source 3
      [DOA] : DOA of the source (1 source case)

2. rules for naming files to be submitted by participants
2-1. source image estimate files and the noise estimate files
[DATA_TYPE]_[NUMBER_OF_CHANNELS]_[NUMBER_OF_SOURCES]_[ENVIRONMENT_TYPE]_[LOCATION]_[SAMPLE]_[FILE_KIND].wav
where [FILE_KIND] :== SrcImgEst1 || SrcImgEst2 || SrcImgEst3 || NoiseEst, if [NUMBER_OF_SOURCES] == 3
      	          :== SrcImgEst  || NoiseEst,                             if [NUMBER_OF_SOURCES] == 1
      where SrcImgEst1: estimated image of source 1
      	    SrcImgEst2: estimated image of source 2
	    SrcImgEst3: estimated image of source 3
	    SrcImgEst : estimated image of the source (1 source case)
	    NoiseEst  : estimated noise

2-2. monaural source estimate files
[DATA_TYPE]_[NUMBER_OF_CHANNELS]_[NUMBER_OF_SOURCES]_[ENVIRONMENT_TYPE]_[LOCATION]_[SAMPLE]_[FILE_KIND].wav
where [FILE_KIND] :== SrcEst1 || SrcEst2 || SrcEst3,  if [NUMBER_OF_SOURCES] == 3
      	          :== SrcEst,                         if [NUMBER_OF_SOURCES] == 1
      where SrcEst1: estimated source 1
`	    SrcEst2: estimated source 2
	    SrcEst3: estimated source 3
	    SrcEst : estimated source (1 source case)

2-3. DOA estimate files
[DATA_TYPE]_[NUMBER_OF_CHANNELS]_[NUMBER_OF_SOURCES]_[ENVIRONMENT_TYPE]_[LOCATION]_[SAMPLE]_[FILE_KIND].txt
where [FILE_KIND] :== DOAEst
