Convention Paper
Toward an Unbiased Standard in Testing Laptop PC Audio Quality
AES Convention 132 · Paper 8682 · April 2012
Abstract
For a rapidly growing population, laptop PCs and tablet devices have become a primary method for watching and
listening to electronic media. Nonetheless, form factor restrictions and placing audio quality second to device
functionality have left a gap in the overall quality of the listening experience. Multiple audio post-processing
solutions exist from audio DSP developers that are included with laptop PCs from a specified manufacturer.
These solutions aim to improve the audio experience for each device. However, the quality of audio produced by
the outcome of these different post-processing solution/laptop PC pairings varies greatly. To date, there have
been no blind systematic comparisons of the audio quality produced by laptop PCs and the subsequent pairing of
a unique post-processing solution. Here we present an unbiased methodological approach for testing laptop PC
devices and report results of audio quality for three different commercially available post-processing solutions as
implemented on laptop PCs from two different manufacturers.
