// Check if user is in GW mode
    if (CSND_initialize(NULL)==0){
    CSND_shutdown();
    GW_MODE = false;
    }else{
    GW_MODE = true;
    }

This is how i check a GW/N3DS on lpp-3ds.

Wait can you explain this code? GW_MODE is set to true if it's in gateway mode? And if not, it shutdown CSND?

also, which bit resolution and sampling rate do i have to use for converting the wav file?

 

[Rinnegatamante]

CSND cannot be initialized with GW so you can check if your homebrew is started from ninjhax or from a GW/other flashcard by seeing what's the result of the CSND initialization (Note that also N3DS cannot initialize CSND).

Someone knows how to use gyroscope?

I tried to use this:

hidScanInput();
    irrstScanInput();
HIDUSER_EnableGyroscope();
float value;
        HIDUSER_GetGyroscopeRawToDpsCoefficient(&value);

But ninjhax crashes when i try it.

You should try it with

hidScanInput();
irrstScanInput();
EnableGyroscope();
float value;
GetGyroscopeRawToDpsCoefficient(&value);

Ok but why do you shutdown CSND if it has been correctly initialized?

also, which bit resolution and sampling rate do i have to use for converting the wav file?

You should try it with

hidScanInput();
irrstScanInput();
EnableGyroscope();
float value;
GetGyroscopeRawToDpsCoefficient(&value);

Solved the problem few minutes ago but i still don't know how to properly get gyroscope status. It seems values are random like it's not calibrated.
When i try do do something like (z * value) where z is the Z result of hidGyroRead, i get variable values even if 3DS is not moving :/

Bitpersample and samplerate can be selected by your own, you have to take them with your WAV decoder by the header.
I shut CSND because lpp-3ds provides itself a function to initialize CSND (Sound.init).

I think that you should use "hidGyroRead(angularRate* rate)".

Ehm... i said "where z is the Z result of hidGyroRead".

Alright, so i put your code just at the top of my code (without csnd shutdown) and then i use GW_MODE to check if i can use it or not to use it?

 

[Rinnegatamante]

Yep, this is used in lpp-3ds for example for processing or not processing audiobuffer from BMPV videos ( https://github.com/Rinnegatamante/lpp-3ds/blob/master/source/luaVideo.cpp )

Did you calibrate the gyrosensor? How much do the values change?

 

[Rinnegatamante]

They change in a range of -500 / 500 (without using the coefficient).

And how can i convert a wav file to .bin?

 

[Rinnegatamante]

What do you mean with BIN? If you mean a RAW audio buffer, you just have to cut WAV header.

 

[AlbertoSONIC]

I have a wav file. I have to convert it to .bin format in order to play it with CSND. Could you tell me how? What do you mean with "cut the WAV header"?

 

[Rinnegatamante]

Take your wav file and cut the header (Audiobuffer starts from 0x04 offset of data chunk in a wav file).

 

[AlbertoSONIC]

I'm trying to convert it using audacity, but all i'm getting is a strange sound... Could someone convert this .wav file? https://www.dropbox.com/s/4oxxt9v7yko2cjr/POP.wav?dl=0

I also tried to cut the header using an hex editor, but it worked partially. The sound is similar to the one i'm trying to convert, but it has a loud and strange sound at the end..

Probably you give an incorrect size to audiobuffer or incorrect samplerate.

32bit float + 44100hz= fail
8bit unsigned + 44100hz= fail

What do i have to choose?

I've seen 16bit signed used
