I just got melonDS since its the DS emu thats worked the best for me. but now I've found that the microphone doesn't work when i play Spirit Tracks.

it will only trigger some times. White noise does nothing. It seems like the threshold for mic activation is incredibly high. So even quite literally SCREAMING into my mic barely does anything.

I have a Blue Snowball iCE and my mic settings work perfectly fine. This is the first time I've ever had mic issues in anything. Please help!

try this mic-test ROM: https://kuribo64.net/get.php?id=jZk9MPy4NUiyevy9

tell me how it goes.


I mean, I didn't observe anything weird here. melonDS feeds raw microphone input right to the DS, nothing fancy done to it. from what I observed the volume was okay (it's controlled by system settings, microphone gain, etc), but Spirit Tracks might be doing something fancy.

Interesting. So then it does seem to be spirit tracks not being sensitive enough.

It's odd the white noise wasn't really working, and that definitely should have been

I'll look into it. basically there are two ways microphone input can be sampled on the DS (12-bit or 8-bit), and one of them might be wrong.


I gave a quick test and the game's mic test seemed to register levels normally...

I'm thinking it might possibly be detecting the levels properly, but the game has a threshold or something similar. I appreciate it though :)

Bit of an update. I tried making a 16bit WAV file in Audacity. Recorded me blowing into my mic and boosted it as much as I could. The mic registers is somewhat still a little jumpy/skippy. It seems more consistent.

Is there a better file I could use? Or how how can I find out more about how the hotkey mic file work? Does it play it once per key press? Does pressing the hotkey toggle? Does holding replay the audio over?

for WAV and white-noise mic modes, it plays and repeats as long as the hotkey is pressed.

external-mic mode doesn't use the hotkey.

same here

tested my mic with the mic test rom: its working (sound a bit low tho).
im trying the white noise option and the wav option too... neither work.

im stuck in the first case of phoenix wright 1. in the game you need to press (Y) and shout, but the game doesnt detect the mic screams, white noise or wav file.

the DS microphone is very flimsy and primitive and so it's quite easy to hit peak with it, which is exactly what games seek for. Microphone input doesn't work well because there are all kinds of mechanisms on software and hardware level made to prevent just that. And white noise doesn't hit peak often enough.

When experimenting with this I recorded a WAV file via a little test homebrew on my 3DS, it works atleast to inflate ballons in Mario Kart DS:

No matter what I can't seem to get past this. I'm playing Spirit Tracks, and I'm using the Spirit Flute for the first time, and nothing registers, White Noise, my Internal Microphone, Nothing.

interesting, we should try adding making melonDS push the volume of microphone input to absurd levels and see how games react

regardless, 0.9 will come with an actual 'blow into mic' sample instead of white noise, that works atleast to inflate balloons in MKDS
