parallel-noise-reduction

parallel-noise-reduction uses spectral subtraction to process audio files and reduce noise in parallel.

Building and installing

See the BUILDING document.

Usage

./build/parallel-noise-reduction [OPTIONS] input-file.wav output-file.wav

Options

• -h, --help: print help message
• --threads: Number of threads to use while processing audio. Default is number of threads in system.
• --noise-frames: Number of frames to count as noise frames while analyzing the audio.

Benchmark

A prepared set of WAV files containing noise is provided to showcase the performance of parallel-noise-reduction.
