Sound with neo geo dev kit and NGFX - Page 1

Hi all,
I am looking for some information about sound and music on neo geo aes system
i use NGFX to edit some waves
I used Audacity to edit a mp3 file and convert it into 18500 16 bit
I put it into NGFX and this one create a V1 and M1 file
When i use Mame, the wav file is ok, the sound seems good, but after 1 minute, it glichs and bug, closing mameui32

So, my question is, how to play music on neo geo (keeping the compatibility with the true HW) ?
Where i am wrong ?

Thanks in advance for your answers guys

Best regards ...

I'm not sure if you have been using this site: https://wiki.neogeodev.org/index.php?title=Main_Page but it may have you answer. I remember it taking a while to get my sound files correct.

All my sound files are 141kbps wavs converted with Audacity. ADPCM-B is used for BGM set to 44100 frequency, left & right,. ADPCM-A is used for shorter sounds set to 18500 frequency, left & right, and volume 100%. M1 is set to cart, M1 size is set to 64k. Vx is set to 1MB.

Hope this helps.

ADPCM-B can be played with ngfx and set_sound command ?

yes it can.

My ADPCM-B is set to 0x21

It is the played with send_sound_command(0x21);

Your sounds.h file will have all the sound values.

Thanks for these answers
