All Dirac had to do was apply their expertise in DSP (digital signal processing) to optimize audio quality. But as phone brands increasingly trim bezels, the challenge grew more difficult. It's admirable that Johannson and Ericsson are that devoted to audio, or else Dirac wouldn't be where it is today. For example, Samsung and Huawei just added a secondary speaker to its flagship phone last year for a fuller stereo sound. "We'd want four speakers on a phone," Johannson says, half jokingly.
