Why would anyone build with this?

REASON 1

Score how clearly processed speech would be understood using the built-in STOI intelligibility function

REASON 2

Generate sweep test signals and extract room impulse responses for speaker system design

REASON 3

Add or filter different types of noise onto audio signals to test processing algorithms

REASON 4

Reuse individual audio-processing functions collected from research papers instead of re-implementing them
