Listen to me

I hope, i don't spoil the challenge too much, but the soundfile i get: is it a part of a song? 'Cuz i only hear some percussion-like tones (like a cymbal) , nothing more.

Oops ....

[A little later:] thanks - got it !

hi...
do you have a hint for me how to generate the soundfile? I think I've extracted correctly the information of the image (many numbers), but how do I get a soundfile with these informations?

Well, I'll give you a very good hint: just listen

Well, I think I'm on the right way (many numbers to audio), but after this conversion, I only get some crazy tones....there's is really no voice. I'm searching for this voice already for many hours - could you give me a "technical" hint? perhaps as PM?

Perhaps I don't see the wood for the trees, but I really have no clue how to go further....

Thanks a lot...

I would recommend to use an audio editor (like audacity) load the file and play a little bit...

you dont need an audio editor, just convert it and listen.
btw, it is possible to convert it even with irfan view, you dont need to write a program at all, you just got to play a little bit

I feel like I tried everything.
I even ran a script like: cat listen.png | cut -b ${I}- | file -
over the whole 18k of the file, to see if it recognized anything. But nothing

.
Also pngcheck found no error nor extra unneeded field.
And I saw nothing neither myself.

I'm lost, what am I missing?

I dont understand how to extract/convert the data.

[Edit:hours later]
i've found it,but the quality is so low it's hardly understandable,
is that normal?
[more hours later]
Grrr. can't get it clear enough.
[edit]
Oh. If you convert it completely, there is no need for an audio editor.

mh, vlc fails to give you the last information. try another player. (at least on osx this is the case for me)

converting to what??

Convert the file to something you can listen to. Examining the picture should give you a hint on the format used.

I did, using a tool known as "the Swiss Army knife of sound processing programs". All I can hear is white noise.

Examining the picture should give you a hint on the format used.

How so? When I look at the picture, it looks to me like random noise. And that is also how it sounds like

Alright, I'm really lost right now.

I didn't see any comments/hints in the file (neither as a comment nor as "color=>ascii" conversions/interpretation) so my assumption is that the data is raw pcm.

I decoded the png into its four channels and discarded the alpha channel. I have a 100*43*3 matrix. At 8192hz that's 1.6s of audio, long enough for an answer word.

Now the problem: no matter how I interpret the data (col, row, color; color, col, row; X other permutations), I only get noise. The FFT confirms this too.

Am I missing something? Did I do something stupid?
