[anteju]

What does this PR do ?

This PR aims to add a tool for generating a set of multi-channel RIRs.

Collection: ASR

Changelog

• Added RoomCorpusGenerator in asr/data/data_simulation.py
• Added unit tests in tests/collections/asr/test_asr_data_simulation.py
• Added an example config and a readme file in tools/rir_corpus_generator

Usage

The tool can be used as

python rir_corpus_generator.py output_dir=OUTPUT_DIR

where OUTPUT_DIR is a path to the output directory. This will use the default configuration in conf/rir_corpus_v1.yaml.

The output will be structured as

OUTPUT_DIR
+--{train, dev, test}
|	+--*.h5
+--config.yaml
+--{train, dev, test}_manifest.yaml
+--{train, dev, test}_info.png

Each directoy, e.g, {train, dev, test}, corresponds to a subset of data and contain the *.h5 files with RIRs. Corresponding *_manifest.yaml files contain metadata for each subset.
