[Galaxy S III General] rafaelpernil:
Graphs and comparisons:

First of all, the i9300 graphs (Wolfson WM1811) and comparisons with other models.

We continue with the US LTE Qualcomm processor SGS3 (Qualcomm WCD9310) graphs and comparisons.

Sound differences between models (Exynos vs Qualcomm):

If we talk about Galaxy SIII audio, we can have different experiences depending of the DAC included on the SoC.

Exynos (Wolfson)

If you have the International model, Exynos, you have the Wolfson DAC, which highlights by his wide soundstage and by its sound clarity and quality. Wolfson is a well known brand by audio experts, formed in Edinburgh (Scotland) in 1984 and since then, they have been making professional audio systems. The best examples, and the most close to our case, is the use of their DAC's in iPods [iPod Video (5G)], in the old Samsung flagship. the Galaxy S and in multiple music players (Meizu M6, Meizu M9...). A year ago, they put their 28 years of experience in another project with Samsung (Previously with Galaxy S) and released the WM1811 DAC, which was going to be incorporated in Exynos 4 Quad SoC of the International Galaxy SIII. They made a pretty similar DAC to Galaxy S one, making compatible almost all the code with the new one http://opensource.wolfsonmicro.com/content/linux-drivers-wolfson-devices). Then, all "supercurio" work (Voodoo Sound) was ported by "Gokhanmoral" to International Galaxy SIII, adding it to his kernel (Siyah Kernel), and by that way, it was possible to raise much higher volume levels without distortion (6db-->63/63) (Original 50/63) and to improve sound quality.

Since that, [MENTION=947981]AndiP[/MENTION] modified Gokhanmoral's work to make Boeffla Sound, which was having a more confortable interface and was fixing FM radio problem when DAC Direct was activated, in addition to new functions (Private Mode and Mic Gain Control). But [MENTION=4167023]AndreiLux[/MENTION] (Perseus kernel author and developer) modified [MENTION=947981]AndiP[/MENTION] work by cleaning his code, and by fixing EQ parameters.

But if that wasn't enough, after all the improvements, my friend Anas Reggoug (@googy_anas) added all additional Wolfson Sound features (Andreilux's work) to Scoobydoo Sound (Gokhanmoral's port) and made it fully compatible with AOSP/CM roms. He also activated an unused 5 band speaker EQ in Wolfson sound and made a sound engine switch, to choose between Stock, Wolfson and Scoobydoo.

Also is notable the default_gain.conf file discovered by [MENTION=1483294]Meltus[/MENTION]. It was the first audio mod for our International Galaxy SIII. This file controls the gain coming from the DAC, and it let us rise or lower volume levels on headphones and speaker.

Qualcomm

If you have the Qualcomm processor, you have the Qualcomm WCD9310 DAC, which is common in all Snapdragon S4 Pro SoC's, even on Galaxy S4's Snapdragon 600 (But it's been improved). This DAC doesn't highlights by his audio quality, in fact, this is the weak point of this version. The Head-Fi experts consider the DAC as quite bad. I couldn't test it by myself, but someone who has a Nexus 4 should know how it sounds.

Jelly Bean latency (93ms):

The sound latency is a problem in Android since always, but in Jelly Bean (Android 4.1), has been reduced a lot. Previously, in ICS (Ice Cream Sandwich, Android 4.0), we were having aprox 200ms of latency, but now, in Jelly Bean, it has been reduced to 93 or 92ms in our case (In Galaxy Nexus, 89ms).

The latency is noticeable when we use audio apps, like Morphwiz, Caustic 2 or a virtual keyboard. Due to it, we appreciate so much the improvement, however it doesn't reach iOS levels.

But if Google work wasn't enough, Sonoma is developing a low latency audio system called "LLA", which attempts to reduce latency to 20ms. http://www.musicradar.com/news/tech...ces-android-low-latency-audio-solution-570274

MIDI-USB by OTG (USB On-The-Go):

If you have an USB-OTG cable, you can use the MIDI function, which is present since Android 3.0 Honeycomb. You can use some apps like Caustic 2 o the apps developed by this developer

It's very fun but it can't be used professionally due to Android Latency (Read older section)
