wav wont open? solved

i found a great train sound to go with parkour pro. i changed it slightly in wavepad, then i saved it as .wav, but when i went into blender and tried to open it in the sound pannel.
it came up with a error, saying:
“Not A Valid Sample”
why is this happening and how can i fix it?
thanks, ionee:cool:

not a good “wav format”, maybe?!
Try to save it as PCM -16 bit - 44 100hz or Mono/8 000hz to save space!

thanks, it was just the pcm thing.
