**Usage:** This demo takes a audio sample and enhances it using DeepFilterNet2. Upload a (noisy) speech sample. You may optionally add some additional background noise to the input sample. If no samples are provided, a default will be used. Long audio files will be trimmed to 10s. DeepFilterNet2 [(link)](https://github.com/Rikorose/DeepFilterNet) is used to denoise the noisy mixture.
