Hello!

Sorry lots of errors posting, but anywho here it is:

Just a fun thread to see what kind of weird sounds you can get out of various .exes and .dlls (PCM Interpretations). To do this, you simply get an Audio Prosessor (Audacity, SoundForge etc) and import a .dll or .exe.

Here's an example:

Hmmm, this is what I might hear on the end of my DSL line.

0_0 Your ISP would hate you XD

I put Sony Vegas 10.exe through Audacity, sounded like a Commodore 64 took a Rainbow Tape.

I remember when I accidentally played the data partition on those early music cd's with data that could be read by the PC and ignored by newer players.

[Nalty]

Oh god I just did this to the Half-Life 2 content gcf and you can actually hear some game sounds D:

inbetween the white noise and the humming

[MatheusMCardoso]

hard dubstep

[That Ninja]

Is it possible to retrieve the dll or exe from the sound? Would be a neat way to hide things in games as easter eggs, or transfer files and such.

Sure. It depends on the algorithm you use as some might cap some of the variables and lose parts of the information, but if you import it in the right way the full information can stay untouched as long as you save it as you don't use any audio compression or so.

Can someone please explain how this works?

I'm thinking the raw file is encoded into the DLL itself, but as to how it can sit there without interfering with any of the code, I have no idea.

When files are saved, of any kind, .exe, .dll, .mp3, .wav, etc. They are saved as binary data. This binary data can be read in any application, but only applications that are built to understand this data know what it should be (so, Notepad knows how to read binary to make sense of .txt files, the LAME MP3 codec can understand binary to make sounds from it, etc.). If you open any .exe in notepad you'll get jibberish as the data stored doesn't make sense as ASCII or UTF-8 data for the most part. So it only makes sense that running a file through something like the LAME MP3 codec would decode the binary into a garbled hellnoise like the one in the OP.

Tl;dr: Any file can be read by any application. Reading the wrong file in the wrong application produces weirdness as the application reads the file how it thinks it should be read, not how it is meant to be.

Edited:

For example. I just ran HWMonitor through Notepad (which took ages to open it because Notepad is horrible). It produced this;


As you can see, there is a readable String in there. So some applications have their String data saved in a encoding that Notepad understands (I want to say UTF-8...), therefore they show up as readable Strings in Notepad. But other bits of data are just arse.

Oh man I opened some random data files from Rollercoaster Tycoon 2 and managed to get the music out of them.

On occasion when you run a file through a PCM, you will hear music stored in the file as long as its in a format the program knows I expect. As you are just reading the binary of the music file through the codec the same way playing that file normally would be done. Not sure if this works on audio stored in compressed archives like ZIP, but you should at least hear something on partially compressed files.

I know for a fact that NES/SNES/NDS roms should give you the audio files near the end of the rom audio. It really is neat how it works.

Does it vary on audio editors?

It shouldn't change based on the editor. But the different audio codecs should produce different sounds to some extent.

[digigamer17]

Also there was a thread somewhere on glitching out pictures just by fiddling around with the audio from the image then outputting it back in the original format.

I tried that but it didn't work out and it didn't do what I was expecting it to do.

Try gcf files

[ntdave71694]

Open "source sounds.gcf" in something like Audacity (it takes a while), highlight the first four minutes or so, and do: Effect > Change Speed > -69.00%

Most sounds play at normal speed :)

[a-k-t-w]

How do you get it to sound like that? When I do it all I hear is noise.

8000 in the sample rate, and 8 bit Unsigned PCM. You'd have to fiddle with audacity's setting to get it to open in that rate.

[a-k-t-w]

thanks, that's heaps better.

[Master Kief-117]

The very endish is a really cool effect. I imagined it as like someone calling for help over a radio, but there's a lot of interference... then it just goes silent... and a few seconds later whatever was attacking screams into the mic.

[Mr. Smartass]

Mine only play for half a second.

Take a .lua script put it through audacity and export it as a .lua.

although its almost not comprehensible there are still some remnants of the script before you put it through audacity.

I believe dial-up used this method for transmitting data.

I think I just went fucking deaf.

Loud noise warning, and no, I don't mean like, it's loud, i mean like ITS FUCKING LOUD SCREECHING EVEN IF YOUR SOUND IS TURNED DOWN HOLY FUCKING SHIT

What's also fun, take an image, save it as raw data, import that to audacity, put a tiny effect on it, save as raw, import back into image editor

This doesn't work for me. Do I have to use a specific audio editor or ROM rip? I'm using (a probably outdated) Audacity.

[[EG] Pepper]

a Kirby 64 rom sounds interesting through audacity, try it.
