Claim:
1. An 802.11 wireless interface system configured to at least one of: wirelessly transmit an audio signal from an electric analogue audio device comprising an electric guitar, electric bass guitar or electrically amplified acoustic guitar, or wirelessly receive the audio signal from the electric analogue audio device, the system comprising: an 802.11 wireless interface device comprising an audio connector jack plug or jack socket in communication with a system that is at least one of a wireless internet system or a WLAN-enabled system, wherein the audio connector jack plug or jack socket is connectable to at least one of an audio connector jack socket or jack plug of the electric guitar, the electric bass guitar, the electrically amplified acoustic guitar or the electric analogue audio device; and a processing resource operable to configure the wireless interface device as a member of a wireless network or to establish a wireless network connection with at least one further device, wherein the audio signal comprises a plurality of data packets, and the processing resource is configured to replace at least one missing or dropped data packet by applying a signal processing algorithm based on at least one further data packet; the signal processing algorithm comprises at least one of an interpolation signal processing algorithm, an extrapolation signal processing algorithm, naive repetition, cross-faded repetition, a fast Fourier transform based model, or linear phase interpolation; the wireless internet interface device further comprises a buffer for storing data packets prior to transmission or after reception; and the processing resource is configured to vary the size of the buffer by increasing or decreasing the size of the buffer in dependence on at least one signal condition, wherein the increasing or the decreasing the size of the buffer in dependence on the at least one signal condition comprises at least one of: a) increasing the size of the buffer in response to an increased number of errors, missing packets or dropped packets; b) decreasing the size of the buffer in response to a decreased number of errors, missing packets or dropped packets; c) increasing the size of the buffer when a quiet portion of the audio signal is received, and wherein the wireless interface device is for wireless reception of the audio signal at an electric audio analogue device, the wireless interface device further comprising the processing resource operable to apply a mute function to an audio output in response to an error, corruption, interruption or delay of the received audio signal.
