An apparatus and method for noise reduction is described. The method and apparatus can be used in a hands-free communication system to provide a hands-free a communication system having improved intelligibility. The apparatus includes a first and a second processor, each separately dynamically adapted to changing signals and noise, to improve a signal to noise ratio. The system and method can operate in the frequency domain and can have an interpolation processor to allow much of the processing to have fewer samples, and therefore, to occur more quickly. The method can also provide and store one or more adaptation vectors that can be used in operation of the system.
