Is there a way to get data from currently playing music on windows ?

[Cactusbone]

hello ! I'm trying to get data from playing music to push it to a ledStrip, I've looked at secondtest.js and it does seems to do what i want but I get a "Failed to start audio stream" whenever i try to set input to "Speakers" i'm using windows 7 64bit. also i'm seeing all my sound devices twice

Is it possible to get currently playing data ? how to do that ?

Nice job anyway :)

Unfortunately, there isn't a way to do that right now. PortAudio doesn't make it easy for some reason, and I haven't had the time to dig in and figure out why.

What are you trying to build? If this is something you really need, I might be able to point you in the direction of some possible solutions.

I'm trying to get leds to light up based on music playing on my computer.

for now i'll settle to using "line in" i guess. thanks for the quick answer !

I've just tried line in to speakers, without any kind of processing on my side (simply returns inputBuffer) and i get a lot of noise and the result is twitchy. if i do it directly in the hd realtek panel, sound is crystal clear (simply increase volume in the panel).

here's part of the logs

WASAPI:2| name[Haut-parleurs (Realtek High Definition Audio)]
WASAPI:2| form-factor[1]
WASAPI:2| def.SR[48000] max.CH[2] latency{hi[0.010000] lo[0.003000]}
WASAPI: device idx: 03

WASAPI:4| name[Line in at rear panel (Blue) (Realtek High Definition Audio)]
WASAPI:4| form-factor[2]
WASAPI:4| def.SR[44100] max.CH[2] latency{hi[0.010159] lo[0.003000]}
WASAPI: device idx: 05

what am i doing wrong ? O_o

Could you post your code in a gist please? I'll try to take a look when I get a chance. There may be some deeper issue within the audio engine

I'm using windows 7 64bit and i'm still seeing my sound devices twice :)

same twitchy sound in vista 64bit with an integrated sigmatel. i'll try using a real soundcard.

I've just noticed sound is far greater (not crystal clear but not too bad) when i set interleaved to true.

ok after more tests, with inputChannels set to 1 and outputChannels set to 1, (interleaved true of false does not matter) the sound is crystal clear. with inputChannels to 2 and ouputChannels to 1, i get some glitches (but not many) interleaved = true slows down music (as expected), but whenever outputChannels is set to 2, i have load of glitches.
