Embodiments of the present disclosure set forth a method of decomposing an audio signal into a set of sub-band signals and detecting a set of signal energy values, where each signal energy value is associated with a sub-band signal. The method also includes generating a noise reduction threshold based on at least one sub-band signal, and, for each sub-band signal, comparing the associated signal energy value to the noise reduction threshold. Based on determining that at least one sub-band signal is associated with a signal energy value below the noise reduction threshold, the method includes attenuating the at least one the sub-band signal to generate a set of attenuated sub-band signals. The method also includes combining at least one sub-band signal included in the set of sub-band signals with at least one attenuated sub-band signal included in the set of attenuated sub-band signals to generate an output audio signal.

In one embodiment, a programmable pedalboard for a musical instrument is provided. The pedalboard includes a docking station for receiving a removable portable computer that provides a plurality of instrument effects. The docking station is configured to receive an audio signal from a musical instrument and to modify the audio signal from the musical instrument based on at least one instrument effect from the plurality of instrument effects.
