The raw data and estimated impulse responses  are arranged according to the 48 configurations which can be downloaded as zip-archives below (approx. 320-400 MB each for the raw data and approx. 3-4 MB for the estimated impulse responses). A zip archive for the raw data contains the following files.

• The recorded microphone signals from each channel for each audio segment.
• Loopback recordings of the loudspeaker source signal.
• Recordings from the dummy microphone.
• A sketch of the configuration.
• A txt-file with the setup.
• A mat-file (in HDF5 format) containing all the configurations.

All the audio recordings were made with a sampling frequency of 48 kHz and stored in the flac-format. A zip archive for the estimated impulse responses contains the

• Wav-files containing the estimated impulse responses. The estimates are computed from the exponential sine sweep.
• A sketch of the configuration.
• A txt-file with the setup.
• A mat-file (in HDF5 format) containing all the configurations.

The configuration number is a four digit number of the form ABCD where

• the first and most significant digit A denotes the type of loudspeaker,
• the second digit B denotes the position and orientation of the loudspeaker,
• the third digit C denotes the type(s) of microphone arrays, and
• the least significant digit D denotes the position and orientations of these arrays.

You can read more about the different configurations in the description of SMARD.

The configurations below are arranged in 16 rows and 3 columns where each column corresponds to the recordings for one particular loudspeaker. Above each row, a sketch of the loudspeaker and microphones are shown within the room. In the sketch, a loudspeaker is marked by a blue star, a microphone is marked by a red cross, and the dummy microphone is marked by a black circle. The exact coordinates of the loudspeakers and microphones can be seen in the setup files below.

If you are a MATLAB user, the data from a single configuration can be loaded into the MATLAB workspace by using the loadSmarData function. The function loads the recorded data and the configuration into a struct.

As detailed on the equipment page, the recordings were made in MATLAB. The code for making these recordings and for estimating the impulse responses can also be downloaded.
