New software to provide enhanced audio playback in smartphones
EDN Europe, 16 Feb 2010Oxford Digital has announced that its MajEq system, which automates the equalisation of sonic performance in consumer audio devices, has been adopted by Dialog Semiconductor to demonstrate improved audio playback for smartphones, portable devices and speaker accessories. The MajEq software will be combined with Dialog’s DA7210 high performance class G audio codec that incorporates the onboard GPF (general purpose filter engine). Equalisation is often applied to portable products in order to improve the sound quality. The new software, when combined with appropriate hardware, provides a fast automated route to tuning and can also produce results that are more efficient in DSP usage than the normal methods involving parametric EQs, graphics or FIRs.
