This repo was created to host only the pointsource noises, allowing for a download that does not include the RIRs, etc.

The original dataset containing all RIRs and noises can be downloaded by:
wget https://openslr.trmal.net/resources/28/rirs_noises.zip

Below is the relevant text from the original README.

This data includes all the pointsource noises
used in the paper "A Study on Data Augmentation of Reverberant Speech for Robust Speech Recognition"
submitted to ICASSP 2017.

Here are the descriptions for each folder in this data:

pointsource_noises: 

The point-source noises
are sampled from the Freesound portion of the MUSAN corpus.
This portion of the corpus contains 843 noise
recordings and each of them is manually classified as either
a foreground or a background noise.
