where to get

[tester]

Question: where can i get so called "corrupted" audio files in various formats, like wav, mp3, ogg, flac, and so on?

By "corrupted" I mean - prepared to test whether and how - the decoding engine will pass them through, whether it will hang, etc. So I guess this means bad headers and bad streams.

Mostly the format is incompatible, ie 69k files 44k converter and all that. Corrupted you can indeed have a bad header,or a bad sector. But that's so far fetched i have yet to encounter one of them.

Here try and fix this Lucky prize goes to the winner!

Another challenge, for not newbs maybe. This one still knows it's PCM.

Generally I need audio files to crash the decoding engine, not ot fix the files. If the engine says that the file is not supported, then the experiment fails. If the engine hangs for unknown reason - then the experiment is succesful. As far I remember corrupted flac files could be a good example of bad behavior.

Thanks for attachements, but engine just rejects them.

Both headers are broken. But the thing with pcm is when you try to break the data nothing happens.. Heres an mp3 (08 , broken it on two places.. one that seemed data, and one that started the same as the header further down. But here it chews right through. Maybe the broken files are just zero padded after a certain point?

Anyway I broke these using a hex editor, just open the file as hex and erase some values.

This one went through.

But I think I know where can I get corrupted and long flac for tests...
