(aka Vibrant, Captivate, Fascinate, Galaxy S 4G, Epic 4G in the US) established the bar high, using a great high quality implementation of Wolfson Micro WM8994 codec. Existing custom mods which tuned WM8994 usage have even been able to drive the high quality higher than most anticipated, as well as the headphone output ranges. Yamaha YMU823 Encircled in Red Above For the Galaxy S II, however, Samsung changed audio IC suppliers, preferring the well-liked Japanese brand Yamaha making a big entry in the the reduced power codec for Smartphones area. The exact chip used in Galaxy S II devices is named C1YMU823 (also refereed as MC1N2). Its datasheet is not public but it a chip designed designed to compete with newest Wolfson and TI choices and probably a customized item developed to follow Samsung specifications. As the growing interest of readers and recent HTC and Beats by Dre strategic alliance exhibits, smartphone audio abilities constantly gain importance. Of program, solid voice call performance remains a significant problem. Numerous smartphone owners now use their gadget as a primary songs player, occasionally with highend headphones. Yamaha MC1N2 codec has some nice theoretical specs, but the promised audio fidelity turns into a dull rendering impacted by a number of excellent problems, relegating Samsung flagship far from the audiophile class. Even worse: only some of these issues can be remedied by utilizing additional gear like an attenuator or an energetic headphone amplifier. Galaxy S II audio output as music participant has issues These days most listeners appreciate music with isolating earphones, as they are helpful for listening to music or podcasts in loud environments with out getting to pump the volume up and introduce listening fatigue. Most inear gear is highly delicate. Combined with reduced impedance and 20dB isolation, hiss and other sound are quickly noticeable. Galaxy S II is not recommended to drive straight sensitive inears because you easily listen to the CPU operating. Repairing the CPU frequency to its maximum (rooted phones only) doesn stop this annoying noise reminding us of inexpensive integrated audio codecs a dozen many years ago. Admittedly, hiss and noise ranges of Galaxy canada goose outlet S II headphone output are a great deal reduce, but these days standard cellular headphones reveal them effortlessly. If you utilizing sensitive inear headphones, radio GSM / EDGE sound is as audible, indicating a probable hardware style flaw mulberry outlet of the codec or the board. The offender is bad EMI shielding.:00 to :02 sound card noise only. :02 pop on codec power up, songs begin to perform. EDGE activated, Quantity one/15 :02 to :35 music playing, you can hear GSM and CPU noises despite the sign :35 Quantity established from one/15 to /15. Songs keeps taking part in in track record but is silent 1:03 WiFi enabled, EDGE is automatically disabled. Moving some cheap beats by dre studio UI elements Due to its bursty cheap dr dre beats nature, cheap mulberry outlet this flaw is hard to expose in measurements and fortunately less audible
