Various implementations include portable speakers with detachable wireless transmitters. In some particular aspects, a portable speaker includes an enclosure housing: at least one electro-acoustic transducer for providing an audio output, a processor coupled with the at least one transducer; an audio input module coupled with the processor for receiving audio input signals; and an input channel for receiving a hard-wired audio input connection at the enclosure; at least one wireless transmitter detachably housed in the enclosure and in communication with a corresponding wireless input channel for receiving audio input from a source device.

An audio processor and method of audio processing for an amplifier system is described. The audio processor may receive an audio signal and adapt the audio signal generating a time varying offset. The time varying offset may be combined with the audio signal resulting in a shifted the audio signal level. The processed audio signal may also be clipped to remove the negative samples values. The processed signal may be used to drive an amplifier designed to only accept positive (or negative) signals such as a class C amplifier.
