QTAudioReader w/ mono mp3 = bad output


#1

Mono mp3’s seem to produce bad output. Chopping noise followed by tinny representation of proper output. I’ve verified using Juce Demo (with quicktime enabled) using a mono mp3 file created using Audacity with Lame.


#2

Are you using the latest version? I seem to remember fixing something like this a while ago…


#3

This is happening with 1.53.30


#4

Could you email me your dodgy mp3 to try? And is this on mac or PC?


#5

I’ve sent you an email with an mp3 and the related information.

For the record:

-Tested on OSX 10.6.6
-Juce 1.53.30
-Outputted sound is very corrupt for 2-3 seconds and then becomes less so. This is regardless of start position.
-Behaviour was found on mono mp3 files for which I do not know the creation method.
-Behaviour also exhibited in Juce Demo with QuickTime support enabled (simply added QuickTimeAudioFormat to format manager)
-I’ve generated test mp3’s using Audacity 1.2.5 with Lame 3.98.2 to verify.
-Stereo mp3’s produced under the same method play fine.
-All noted mp3’s mono or stereo play fine in QuickTime Player and VLC with no audible glitches.
