WAV header fix

by Udo-12 :: Rate this Message:

Hello,

Could the WAV header reading be slightly modified to not assume a 44-byte header but to scan for the 'data' portion?
(possibly using strstr function)
This way most of the header issues will be fixed.

I see that audacity writes 84 byte headers when disabling the metadata editor, so we don't have to scan many bytes or change much code.

Kind regards,
Udo

This is what Lee does in its dev version and some of it should make its way in mainstream soon.

09.05 update to be released either today or tomorrow, weather permitting.

Can it be sooner please? :-)
For every DVD-A I suffer a bit from this issue.

I'm happy to hear that this feature of version S may be included in the mainstream program.  As Udo has surmised, the code required is neither long nor complicated.

Indeed. Also audacity is on the brink of including a tickmark or whatever to turn off their metadata routines so that 'standard' WAVs are written

So all this means that `soon` there is even less reason for error...

Kind regards,
Udo

To get rid of junk in headers, you can use shntool as an alternative:
   shntool strip file
canonicalizes headers (I've had crashes however with this tool).
