[MOD][MCU] BD375xx Sound Processor

[dromede]

Why not MTCE_LM_V3.42bd a newer one I posted a few post above ?

Indeed, I did find out later that there are patched versions newer than mine.

I tried yours and it worked just fine. ^^

While the soundmod works fine, my unit is having issues with audio distortion that gets worse over time.
It does not affect all channels, but over time, right channels become downright unusable.

I think that something is overheating, amp or the BD chip.

Real development thread deserves to be sticky/bumped

After doing some searching and all I can't confirm that any patched firmware is compatible with my unit. I'm not sure if it is or is not MTCx, but the MTU reads TS907 as seen attached. Any work been done on these or anyone know if anything is compatible? About to switch back to stock head unit because the bass is so bad haha

Not an MTCD/E unit so wrong forum, wont work on your unit.

Where would you think to start

Where would you think to start

Well I've searched the mcu, non mtc unit, sound mods etc. Not sure

What is the mcu version. Does it start with MTC

Dumb question, but how does this relate to adding a hardware-dedicated 15-band DSP (like the ADAUXXX / the ones integrated with some of the radios)?

Does the sound quality improve in your opinion?

I was planning on adding a DSP at a later time which should improve the sound quality. I have not done it yet but that's the idea around adding an external unit.

Hi i would like to do this modification.

But my current MCU is 3.55 (HXD) and the modded version are older, i did find within this forum and other forums updated version of my MCU but they are not patched.

Could someone patch these?

Seems like this topic died?

 

[bombername]

We guess that, too.
We wish this topic would be reanimated.

But it's free to try it yourself.
Or find another DSP solution for your device.

Hi,
I installed the Sound mod a long time ago.
Now I want to upgrade from Android 9 to Android 10.
Should I flash an original mcu for this or is it also possible with the sound mod mcu?
Thanks in advance.

I think mcu mod will work with Android 10, but you will need an updated Mixer app. If I'm not mistaken, I've seen it on this forum.

The MCU and Android are entirely unrelated.

 

[Jules_1606]

I know but it is often said in tutorials that you should install the latest MCU before an Android upgrade

 

[typos1]

Indeed, but nevertheless the MCU and Android are entirely separate and therefore nothing different is needed to modify the MCU.
