Mid-side (M-S) encoded audio is reproduced by a device that includes a multi-channel digital-to-analog converter (DAC). The DAC has a first channel input receiving a digitized mid audio signal, a first channel output providing an analog mid audio signal, a second channel input receiving a digitized side audio signal and a second channel output providing an analog side audio signal. The DAC may also include a third channel for receiving a digitized second side audio signal. The second side audio signal is phase inverted. The device may be a handheld wireless communication device, such as a cellular phone, and may also include transducers for outputting M-S encoded sound in response to the analog mid and side audio signals.
