I am tying to upload a kiai. Any clue about this error? i have a file 4.85 sec at 44100 SR,16 bit....I was using this file 1 month ago. Now i get this error with every file i upload. (Tried the export with Cubase, Audacity, Sound Forge..... nothing works)

Are you sure saving it in .wav format?

For me when using audacity for TB, I always save sounds as other uncompressed files:wav(microsoft):Signed 16 bit PCM and they work for me, sometimes different coding does not. So try that first.

Yes. I use wave files. I have used the same kiai before with no problem. Even if I upload my current kiai i get the same error

I guess they're broken again. Guess you should use the old one for a while
