that music matching software is also present on other SE mobile phones.
it works by recording a sample, sending it via *inet* (????), "recognising" it via a database and sending the result back.
there are also some online services that do the same, only you can "sing" the sample yourself! ;^)
i guess, the nds' mic should be good enough for such a task, as audio sample recognission would (iirc) "degrade" (band filter) the signal for pattern matching anyways. ;^)
the hard thing is to make the backend work, that means the recognition itself.
good luck! :^D
EDIT: ok. ;^D

I never said I was attempting anything ;) just wanting to know if the quality would reach.
BTW: other opinions ?

What's so ???? about *inet* compared to Nintendo Wi-Fi Connection?

Guess what ? That was exactly my point ;). Anyway, thx. I just was curious about the DS's mic capabilities.
Topic can be closed if you like... except somone wants to add something.

@ tepples: ???? i meant, at least over here in germany, mobile inet still costs like ... 20 cents per 10kb (or a bit more, i don't know what's "on" these days, last time i checkted was half a year ago, when my old phone started to download madonna in my pocket...), which is rather pricey. so, such a "nice" "feature" is quite a "milking machine". annoying "quotes", i "know". ;^D
so, what's with nintendo's wifi? (a service?) i know nothing about it.
EDIT: i'm totally lost... ????

I guess he means the comparing would take too long since the DS's Wifi lies between 5~8kb/s max... aside from this you would have to be near a AP, which kind of defeats the point of this.
Although it might be useful to record it, then when in reach of a AP send the sample.... still a pc could be used for matching the databases up so.
Idea defeated.
Game Over

oh, now i get it! thanks, pas! :^)
-> GMAE OEVR, MAN! ;^D
ps: about the mic again - recording samples with nitro tracker yields quite usable results.

there are audio formats the shrink to almost unimaginable sizes. I'm sure a sizeable database of songs could fit on one 2gb card couldn't it? am i missing something?

Matching two songs together is done via "fingerprinting" both the search sample and the real song. It's unlikey that it'd be doing anything close to a high-quality waveform comparison, and a fingerprint could probably end up being very very small, only a few dozen bytes.

so ?

So...the ds doesn't have to connect with some online database. The files that audio will be compared to can be stored on portable media.

ok, before i post something retarded, we are talking about comparing the signal from a part of a song to a "fingerprint", right?

... a "fingerprint" of a song to the "fingerprint" of a sample... right.

Sure, thats the idea.
I wasn't suggesting where you actually store and compare it, but I was letting you know roughly how the comparisons would have to work.
Possible things to "fingerprint" with are the beats per minute. Or the rhythm beats of a song.
Check out www.songtapper.com for a working example. It seems to expect a "tap" for every sound "sylable" to a given song.
eg: 'Hap Py Birth Day To You'

if it's that slow, you're doing something wrong. I easily get 40kB/sec, and I've heard people getting up to 100kB/sec with some optimization. (iirc, according to sgstair, the dswifi guru, the theoretical maximum he thinks he can do with hacks is ~120kB/sec)
