- K.A.T*.apk Android application: *NEW*
It contains most of the different features:
- ability to control individually the volume mixers of the WM8903 chip (more controls will be added later)
- predefined optimized profiles that can be applied at boot and run time (custom user profiles will be available later on)
- Speaker front boots( DAC L+R merge)
- Abitility to link Speakers and Headphone analog volume with the volume keys and cascade analog with android digital level.
This will give you the best quality results.
When you increase the volume it will first increase the digital android volume, then increase the real chip analog volume as you keep pushing up once the digital volume has reached the maximum.
When you hit the volume down button, it will first decrease the analog chip volume, while keep the digital volume at max.Then once it has reached a low analog level it'll decrease the digital slider as you keep pushing.
If you prefer not to have that behavior and set the volumes separately, just uncheck the cascade option.
- reinit FM34 DSP feature (in case you prefer not to install the "crap sound / mic fix", you can still reinit the dsp that way)
* Install section allows you to install the different patches/features and fixes
- HDMI & crap audio after Mic Fix + Mic level increase (might require a reboot, if you've been using the audio before installing the fix)
- K.A.T MediaScanner Service (allows you to define filters and such at run time, see below)
- wpa_supplicant for adhoc (wip) Currently will allow you to see the networks, but will most likely time-out when trying to connect (requires you to turn wifi off /on to be seen)
- Ad-blocker (host file replacement)
Allows you to mount / unmount drives:
- Mount(Auto): will try to mount vfat, ext4 and ntfs with what the kernel support (ie if the kernel only supports ReadOnly NTFS, the drives will end up being mounted ro)
- Mount(NTFS with full write support) : this one will try to mount the drive directly with full read-write support through ntfs-3g compiled and included with the app.
- Unmount: does what it says
if the drive is busy or used by an application, it'll usually fail.
In that case and if you know what you're doing you can try to check the force box, it might be able to force unmount.
Allows you to configure the KAT MediaScanner filters
Always been annoyed by the MediaScanner eating 50% of the cpu and doing intensive IO, bringing your tablet to its knees ?
Well this enhancement is for you, it'll allow you to black/white list and force specified directories scanning, or disable scanning completely.
The way the default JB MediaScanner works is that everytime the tablet starts, that you mount / unmount a storage, or that the tablet wakes up,
the MediaScannerService receives an order to scan.. *everything* on all mounted medias *again*:
/storage/sdcard0, /Removable/MicroSD, /Removable/USBdisk1, /Removable/USBdisk2, /Removable/SD
That's where the K.A.T MediaScanner comes to the rescue.
With it you can rewrite / filter the scan orders.
Everything added in it will continue and be scanned if the order is received.
If you work in whitelist most, you should add at least /system/media to it, unless you don't want the system to find these. (default audio notifications and such)
Everything in this list will be discarded from the scan order received.
- Always add directories
The directories in this list, will be always appended to the scan order.
- Scan checkbox: if unchecked all orders are cancelled
You can choose to still let the "always add directories" list pass or not with the additional check box
One thing to understand: the MediaScannerService is in charge of "top level" recursive scan orders.
Meaning that it receives the order to scan /Removable/MicroSD for example.
(It can also receive individual scan orders for files if an application forces it, but that's not how android is doing it for you general "media files")
So it is these "orders" that the filters can intercept and what the white/black list are matching against.
You won't be able to match onto individual files.
Also keep in mind it takes time for the scanner to update its DB.
Until it's done you might still see medias that you've filtered out, or might not see new medias you're trying to force scanning.
If you currently have a big media DB, the cleanest and faster way to do it, is to configure the filters you want, wipe MediaStorage data, then reboot.
- Voodoo Sound enabled kernels:
See Voodoo Sound dedicated thread
(do not use if you want to use KatAudio as the voodoo sound app will change the values, and both apps will fight for volume keys and levels)
