The Noise Reduce software comes with three applications for use in the noise reduction process. The list below gives a brief description of each application and links to the specific usage page.

• GNP Generates a noise template file from an audio file
• GNI Reads a noise template file and writes its data into a CSV file (useful for examining and graphing the template in a spreadsheet application)
• NR The main mode of operation. Removes the noise from an audio file using a noise template generated by GNP.
