      The Future is this - Step by Step Video for Extracting Digital out from Android Phones*

      Hi Folks,

      I ve been dreaming this day for the last 2 years. I ve backed out of the Carputer way ever since i saw the Capactive touch displays of 4" Android Smartphones. Becasue whatever configuration of Carputer you make, a good quality Capacitive Touch screen which is practical still seems an hard reality for most on budget.

      An Quality Android Phone + the option to bypass the internal DAC was in my dreams always. I had a vision of replacing the Headunits with Android Phones and Still experience Quality Sound. I scrapped my Carputer Project way back in early 2011 and been upgrading Phones and updating custom roms in search of the Audio over USB (Host) that was evading android devices till a couple of months back. I resisted all temptation to turn to Carputer as i was hoping something would come up soon - As my faith and hope faded, i evenutally switched to iphone (4S). But that platform was too restrictive for my liking.

      I researched around and got hold of the HRT Streamer - one of the few DAC's which doesnt need an external PSU and a VFM factor which is unbeatable. I got all the Accessories needed. and Kept on Changing ROM to ROM all builds from nightly to RC to Stable were thrown at it - but just couldnt get the output light on the DAC to glow.

      One fine day, i got hold of my boss's S3 and Hooked it and voila the Light came on ! My joy knew no bounds, but then i need to have a working POC so that i dont end up dissappointed. As i searched for a droid that can fulfill this Requirement, the Galaxy Note 2. I got this at 8 PM Yesterday and the first thing i did (apart from posting in FB) is that i went and checked this out. I played a WAV file and the Results was Fab !.

      I have made a video of the same;



      The Player i used is Neutron - To me its by far the most advanced player ever made on Droid platform. What with 4 band full range Parametric EQ, Slopes, PreAmp control, Rumble Filter, 64 bit Rendering, Auto Gain Protection and so on...

      I am dying to try it out in my Car. Hopefully few other things like car mount should be done in net 2 weeks. So Stay tuned

      *Android Phones - Currently tested on Samsung Galaxy S3 and Note 2.

      I'm hooked to this one ... planning something similar and can't wait to get my Galaxy Tab 2

      A small step towards, Samsung, Apple, Microsoft or Google In Car Entertainment systems.

      EDIT : you may find strange that I added Apple to the list, even though it does not have USB. I am sure people will find a way to use IPad mini as a head unit, through Other interfaces.

      DSP's generally accept SPDIF / Coaxial as Digital input apart from Regular Analog Ones. Now, i can still have a converter to take out the Digital via USB and use an Adaptor to convert it into a SPDIF - But you see it requires a seperate Device and a Power source to Function. More Devices, more chances of noise and more chances of screwing up.
      A DSP's core functionality can be replaced with a Amp's onboard XO + A Player like Neutron. Only in Active setups you ll need more control where a DSP makes sense.
      Second, few processors like Bit one / ten have limitation in DAC end (can play only 44.1 Khz / 16 Bit) Whereas this can play files upto 24 bit / 96 Khz.
      And Finally, the Cost Comparison of DAC to DSP is atleast 4X !! Unless i go for Active setup why would i spend 650$ to get a Processor when i can get same SQ at 150 $ ?

      This is taking the Digital out, so it wont work on AUX (which is an Analog out)

      SO how do we play it on our car speakers or a new HU is needed? Please clarify.
