1245546 - Wave Decoding on problematic files, and 6-8 channel files

Status: RESOLVED FIXED

(Core :: Web Audio, defect)

Description

[git]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:44.0) Gecko/20100101 Firefox/44.0
Build ID: 20160123151951

Steps to reproduce:

I'm working on an audio editor and was testing some multi-channel files.

This specific file loads in Chrome, but not in Firefox:
http://www-mmsp.ece.mcgill.ca/Documents/AudioFormats/WAVE/Samples/Microsoft/6_Channel_ID.wav

This is low priority IMO, but there's a good list of audio test files located here:

http://www-mmsp.ece.mcgill.ca/Documents/AudioFormats/

I'm not sure how crazy you want to get with supporting all file formats.


Actual results:

The call to decodeAudioData() failed.


Expected results:

I would expect the call to decodeAudioData() to succeed, either by giving me an AudioBuffer with 6 channels, or giving me the audioBuffer with a supported channelCount (if 6 channels is more than the valid maxChannelCount).

Thanks for the update!  BTW- I updated this test suite to include some of the problematic wave files: https://chinpen.net/decodethis/

You can compare the Firefox results to Chrome.  I'm not sure if it will help in your testing or not.

Fixed in Mozilla-central now that bug 1231793 has been fixed. Wave files with multiple channels (more than 2) should now play.
