handle JUNK in your CHUNK

[geoffreyfloyd]

The WAV files created by Adobe Audition include a 'JUNK' chunk that comes before the 'fmt' chunk, so code was added to recognize the JUNK chunk, move past it, and properly continue with the expected fmt chunk.

Great, thanks Geoffrey, I use Adobe Audition often, too. I'll test this out this week.

Hi @geoffreyfloyd, everything seems to be working, but I wasn't able to generate a "junk" wav file from Adobe Audition.

Can you supply the file in question and/or advise on the following:

• what version of Audition are you using?
• what parameters are you using when you save the Wav file?

Hoping to replicate the issue in the current version of this module so I can finish out this pull request. Sorry this has taken so long...

Thanks for your help!

@geoffreyfloyd - Did you see above? I can't test this PR without a sample file, so I'll close this if I don't hear back.

Thanks again for your help either way!

Hi drj-io,

I try to re-open this bug. Also me found this problem in Audition. I can send you the audio files do you want. Let me know if you have a repository where I can put the audio files.

Hi, I spend time looking for this fix. I tried with a junk wav file and give me an error with the main branch
but was OK with this one. Here is the file I used. I get it from my customer.

Ps, this is a zip because github don't allow uploading wav file directly.
15SEC LINGO(1).wav.zip

Looking forward for this merge request :)

Thanks for such a work 👍

Hi, finally I have made a pull request that handle JUNK files correcly and other useful improvements to this great lib.
I had errors with bext wav files. This PR may be future proof because it search directly the fmt chunk, bypassing all other metadata instead of reading bytes by bytes.

#25

Bext file example: (I have a github error because the file is 35MB so uploaded to my server)
