Mike has already spent a lot of time on it, it makes sense to go just one more step and get that 46.9 % of the market share (which is really about selling more units and it could very well triple that sales), they can do it on a Version 2 release and an offer to upgrade the first release for $50/$100 bucks (like a service they offer for 1 ohm mod) and I know its not that hard as I saw a whole list of portable amps/Dac that already support Android 4.
And since it was mention that " it gets asked nearly every other page." Centrance should really sit up, notice it, as android is a force to be reckon with.
I think you’re right!
I don’t see how the others can strive against the free and open source Android OS.
And Android relies on Linux for core system services such as driver model. Thus Android handles all the things that Linux is really good at such as a vast array of device drivers, which take the pain out of interfacing to standard peripheral hardware.
In fact, existing CEntrance USB DACs, DACmini or DACport, can work with the stock Samsung Galaxy S3 smartphone using 24/192 capable USB Audio Recorder PRO app:
"Samsung S3 > Centrance DACport > Final Audio Design Heaven VI, blissful!"
A lot of stock Android devices, using USB Audio Recorder PRO or not, reportedly interworking with USB DAC are listed at the following link:
There are two ways to implement USB audio for Android:
1. USB audio driver, like free open source ALSA Linux USB audio driver, in the Android Linux kernel (native solution)
2. USB audio service at the user space, using the USB host driver
A USB audio service is included in the USB Audio Recorder PRO music player.
The Galaxy S3, the best selling Android device, using USB Audio Recorder PRO can work with the CEntrance DACport, and the same Galaxy S3 using native USB audio driver can’t:
apparently CEntrance engineers and Samsung engineers don’t have the same interpretation of some USB specification part.
Put in other words, the implementation of USB audio by Samsung developers is not enough tolerant to the USB specification than the one by USB Audio Recorder PRO developers.
As it is much easier to modify a software program of the Samsung device than the firmware of existing USB DAC, a fix of the Samsung native USB audio could be done using two USB traces:
. 1st USB trace capturing USB packets exchanging between a Galaxy S3 using USB Audio Recorder PRO and a DACport
. 2nd USB trace capturing USB packets exchanging between a Galaxy S3 using native USB audio and a DACport
I asked Samsung to improve their USB audio software:
It should be ideal if CEntrance forwards to Samsung the two mentioned USB traces as well as the USB descriptors of the DACport.
