    Hello everyone,

    thanks to new payloads and new libctru branch by smealum and his team, we now have access to a lot of new services and i noticed RetroArch is now using DSP service for audio (lpp-3ds will be the next one, i'm working on it).

    Anyway, in the future, a lot of homebrew will use dsp service for audio but to use it you'll need a DSP firmware dumped from a retail cartridge / eShop title and to do this the only solution at the moment is to pick code.bin file with braindump and process it with Retroarch to extract the dspfirm.cdc file you need (This problem happens only for NH 2.1 or lower users and CIA/3DS users).

    This problem appears only for non-2.5 *haxs users cause new payloads have a built-in dsp firmware. What this homebrew does is to extract this firmware and let you use it on 3DS/CIA homebrews or on NH 2.1 or lower.

    Thanks to @ihaveamac for the tests on *hax 2.5.

    Latest version: 0.8

    Hey! Could you link me to somewhere where DSP is being used? I would like to know how I could use it myself.

    Brilliant. This will have to be linked with all CIA distributions now, which is lame. Would be nice if this was integrated with hb menu or something, auto dump if firm dump isn't present. Then nobody needs to worry about this.

    Sorry for my ignorance, but what are the benefits of DSP?

    Just better/proper audio functionality. It's mostly a technical difference. CSND wasn't meant to be used for a game's audio really, more for system/background stuff, applets, etc.

    Can it improve performance in any way?
    Also, how do I use the dspfirm.cdc in retroarch?

    Edit: Seems it has to beplaced in RetroArch/cores/system/
    No wait nevermind, has to be in /3ds/ for some reason... i think?

    It can improve a lot audio quality cause it can use different kind of interpolation (like the polyphase ones) and also have support for audio surround (still under research from fincs / Lectem).

    To use dspfirm.cdc you just have to launch the homebrew. It place the firmware automatically in the directory Retroarch and all the others homebrew will go looking for ;)

    I really hope that with this, a parametric / graphic EQ finally comes for the 3DS!

    @Rinnegatamante,
    Are you saying if I am on *Hax 2.5 I do not need to do anything with DSP?

    To be honest all I understand is that DSP is supposed to be a better audio output and I am trying to figure out if I need to get it or not.

    I'm sorry to bother you, but I don't understand at all how it works.
    I'm looking for DSP for Retroearch, and I downloaded your DSP firmware Dumper tool v.08.

    I started from CN Hax 2.1 the tool, and it says error. I tried with both a retail cartridge game or not.
    I obviously does not understand even me what I'm doing ah ah, so please help me! :wacko::P

    You have to launch the Dumper from NH 2.5. Then you can switch to NH 2.1.
