A challenge to all self-proclaimed audio experts...

It is a single channel (mono) audio clip running at 8000Hz and compressed at 33kbps, however whatever created it has tagged the codec required as DEVELEOPMENT. Without knowing what codec was actually used to encode the file, there is little chance of getting anything useful from it.

What is it's origin ?

Edit : a little scrounging in google says it's encoded with Micronas InterMetall Speech MI-SC4 v.4.2.4, but I can't find a codec for it anywhere.

Maybe this:

Nevermind, the link was dead.

[guns1inger]

Link isn't dead. The file is now attached to this post. Although it doesn't seem to help with the test file . . . . . .



mi-sc4.zip

The link probably didn't work for me because I have cookies blocked by default.

Would you mind telling us where you found that unplayable audio file

[jman98]

Well, it's still early in the day for Canada, so he might respond later, but given the subject of this post, I'm amazed that so many of you want to help this guy. That was a pretty rude way to ask for help. Or maybe it's just a test and he has deliberately created a file that you guys can't play, just to mess with you.

@ jman: thanks for the alarm-clock (seriously)
@ the OP: see link below :P

playable.wav

[rimmonhouse]

I didn't intend for my subject to sound rude...I thought I'd just try to spark some competition. The file is real and is not a trick, and I've literally been trying for over a year (on and off) to try and find a way to play it. I've tried the mi-sc4.zip before, but unfortunately it didn't work.

Midzuki: is that the converted file? is the file only static? (that would be an extremely disappointing end to this mystery.

[poisondeathray]

I'm no audio expert, but the audio file plays back: "Hello, hello, _____ is a dork"

I won't spill the beans on how I got to play it back just yet

2) You still haven't told us where you found the damn test.wav

1) Like it or not, jman98 is right --- your opening post did sound
trollish. As for the file playable.wav: I opened test.wav in GoldWave
as an 8kHz-sampled mono bytestream and simply saved the result as
an uncompressed, "hearable" audio file. Why? Because I serious doubt
the original mysterious.wav can really contain anything worth hearing.

I've tried the mi-sc4.zip before, but unfortunately it didn't work.

The codec needs to be registered. The system won't know to associate the fourcc code with the codec until it is. It needs an INF file.

[poisondeathray]

Jagabo is correct (as usual), but I hate fiddling with registry edits or installing extra stuff

The codec is the correct one, it just happens to come with Mplayer (it has many self contained codecs, like VLC)

Here is the file re-encoded in mp3

out.mp3

[jagabo]

I downloaded this driver

and installed it on a virtual machine. The WAV file matched Poisondeathreay's mp3 file.

[Midzuki]

Sadly I am right --- not worth the effort.
