WELCOME to the dECHORATE dataset

⚠️ This work is under review: Be very careful here!

dECHORATE: A calibrated dataset for echo-aware audio signal processing

The dEchorate dataset is a new database of measured multichannel Room Impulse Responses (RIRs) including annotations of early echo timings and 3D positions of microphones, real sources and image sourcesunder different wall configurations in a cuboid room.
These data provide a tool for benchmarking recentmethods inecho-awarespeech enhancement, room geometry estimation, RIR estimation, acoustic echoretrieval, microphone calibration, echo labeling and reflectors estimation.
The database is accompanied withsoftware utilities to easily access, manipulate and visualize the data as well as baseline methods forecho-related tasks.

Keywords: Echo-aware signal processing; Acoustic echoes; Room impulse response; Audio database; AcousticEcho Retrieval; Spatial Filtering; Room Geometry Estimation; Microphone arrays.

You can find a detailed explanation of the dEchorate dataset at: dEchorate: a Calibrated Room Impulse Response Database for Echo-aware Signal Processing

dEchorate has three main elements:

  • the data (available on Zenodo);
  • the code for working with dEchorate;
  • the code for reproducing the paper.



  • 03 May 2020: v0.0.1 dEchorate project is alive

Get the Data

The data is available at Zenodo. Please, follow that link to download (part of) the data.

The dataset is available in multiple ways:

  • Annotations/labels/metadata: csv file that can be used pandas (Python)
  • Only RIRs: numpy matrix n_samples x n_mics x n_srcs x n_rooms (~ 6 GB)
  • Only Speech: numpy matrix n_samples x n_mics x n_srcs x n_rooms (~ 6 GB)
  • Raw data: an hdf5 file (~ 75 GB) containig all the raw recording data (chirps, speech/noise sources, babble noise, room tone)
