es-ES	wiki	twilightmenu	customization	Skins para DSi/3DS - Efectos de sonido personalizados	Cómo usar música de fondo y efectos de sonido personalizados en las skins de DSi y 3DS de TWiLight Menu++

TWiLightMenu permite usar sonidos personalizados en los temas. Coloca los archivos de sonido en la subcarpeta sound de tu tema. Por ejemplo, para el tema white, pondrías los archivos en themes/white/sound/sfx.bin y themes/white/sound/bgm.pcm.raw, respectivamente. Both files are optional, if bmg.pcm.raw is missing, the default music will be used. The same thing would happen with the sound effects if sfx.bin is missing as well.

En esta guía se asume que tienes instalado devkitPro con mmutil. Puedes descargarlo en la página de devkitPro.

Banco de sonidos

The sound effect bank (sfx.bin) contains sound effects such as the icon select sound, etc.

Archivo	Descripción
startup.wav	Suena al inicio. Ve a la sección de Sonido de inicio para más detalles
back.wav	Volver
launch.wav	Suena al abrir un juego
select.wav	Played when moving the cursor in the per-game settings and select menu
wrong.wav	Suena al llegar al final de la página
switch.wav	Suena al cambiar de página
stop.wav	Suena en el Tema DSi cuando el cursor deja de moverse

All the files listed above are required to build a custom sound effect bank. If you want a sound to be mute, you can use a silent audio file. The .wav format is mandatory and the encoding must be PCM.

This file includes the sounds used in the default DSi and 3DS themes, along with the makefile used to build them into a valid sfx.bin file. Feel free to edit and change the sound files to make a custom sound effect bank.

To build your custom sound effect bank, open your terminal (or command line if you are using Windows), change the current directory (cd) to the folder where Makefile is, and then run the make command. You will get a resulting sfx.bin file that can be copied to the sound subfolder in your theme folder. This file must be under 512000B = 512 kB. Any file larger than that will result in either crashes or some sounds not playing fully.

Sonido de inicio

While the other sound effects will work with any WAV file with PCM encoding, the startup sound must be in a specific format in order to work properly, otherwise there will be a gap between when the startup sound stops and the background music begins.

The startup.wav file must be 16-bit 16 kHz. You can use Audacity for example to convert to this format. Once the file is loaded in Audacity, change the Project Rate (Hz) to 16000, then press Shift+M, and change the Format to 16-bit PCM.

If your file is in Stereo, you should also go to Tracks > Mix > Mix Stereo down to Mono.

You must set PlayStartupJingle=1 in your theme.ini for the startup jingle to play.

Música del menú

Menu BGM needs to be a 16-bit 16 kHz Mono raw PCM file. Below are two methods for converting audio files into that format.

Unlike sfx.bin, bgm.pcm.raw can be arbitrarily large.

ffmpeg

The simplest way to convert music for use in TWiLight Menu++ is to run this ffmpeg command in a terminal:

ffmpeg -i [input file] -f s16le -acodec pcm_s16le -ac 1 -ar 16k bgm.pcm.raw

Replace [input file] with the name of the file you want to convert. You can usually do this by simply dragging the file onto the terminal window with the cursor in the correct location.

Audacity

If you don't want to use the command line you can also convert using Audacity.

To convert the audio:

1. Abre el archivo con Audacity
2. Si tu archivo es estéreo, pincha en la canción y selecciona Tracks > Mix > Mix Stereo down to Mono
3. Cambia el Project Rate (Hz) en la parte inferior izquierda a 16000

To export in the correct format:

1. Selecciona File > Export > Export Audio...
2. Pon File Type a Other uncompressed files
3. Pon Header a RAW (header-less)
4. Pon Encoding en Signed 16-bit PCM
5. Pon como nombre bgm.pcm.raw y pincha en Save
6. Pincha OK en la edición de metadatos

Now you have a bgm.pcm.raw file that can be copied to the sound subfolder in your theme folder.

You should then set the DSi/3DS Theme Music option in TWiLight Menu++ settings to "Theme" for your custom BGM to play on the menu.
