RIR samples Darmstadt and Helsinki, Summer-Autumn 2018

This dataset contains Room Impulse Response (RIR) measurements that we collected for evaluating the DoubleEcho proximity verification system. The package contains the original RIR sample recordings, processed audio files after deconvolution with the original signal and cropping the RIR, and precomputed features in CSV files. All the audio files are 16bit mono PCM Wave files.

The original.wav file is the generated excitation signal that was emitted in the rooms.
Other files follow the naming convention recorded_ROOM_emitter_EMITTER-ID_RECORDER-ID_TIMESTAMP{_cutrir}.wav
The files where .wav follows directly the timestamp are the original recordings; the ones with cutrir in their name are the cropped RIR samples.

The CSV files contain extracted features like the RT60 value for the entire signal and for specific frequency ranges. An example of the extracted features of a single sample:
