Erik is right,
In addition to my "generic" answer.
When i get trouble with a sound file ( which happen very often :( )
I do the following:
I try to load it with Audacity ( at least version, 1.35 )
=>If it load correctly => you can see the curves and you can listen the sound
==>You check the rate ( 8000, 16000, 22050, 44100, 48000, 96000 ) , and
if
required you convert to the right rate.
==>You check the bits PCM ( 8, 16 , 32 float), and if required you
convert
to the right bits PCM value.
==>Then Export the file to WAV format
=>If it do not load correctly, try with sox ( version 1.2)
The command line for instance to convert the sound file to 48000 rate 24 bits
PCM is:
sox -S yoursoundorigin.vaw -b 24 -r4800 yoursoundconverted.vaw
sox will tel you how was the original format of the sound, and convert it.
Then you can convert again that " yoursoundconverted.vaw" sound to a less rate
and bit values ( Aircraft sound is not HIFI, only NOISE :( ) -r 8000 -b 8
Doing this, i have been able to save a lot of live recorded music done with
an old digital recorder.
I hope, it should do for you
Cheers
BTW: you will notice that Audacity is very accurate since you can improve the
sound with it, with the filters and effects tools.
