Transporter will not play high bit rate 24/96 aiff file.

Customer said this file used work previously, he is not sure what the previous version of SC he had, but he had done the upgrade on 12/20/2008, I tested file it will not work in our Transporter also. I tried it with 7.0, 7.2.1. and 7.3.1. RN= 081223-000813
Created attachment 4653 [details] Aiff file
For reasons that are not obvious to me FLAC chokes on the attached aiff file with ERROR: SSND chunk size inconsistent with sample frame count. Disabling AIFF to FLAC playback allowed the Transporter to play the file. SoX was able to read the file without issue. Alan, perhaps we should switch from FLAC to SoX for transcoding wav and aiff going forward. SoX appears to be much more robust when it comes to input files.
Maybe. Bug 10660 already covers this. But we will probably loose seeking ability with AIFF if we do that.
Hmm, I thought bug 10660 just covered downsampling however this file does not require downsampling to play on the Transporter. Am I mistaken?
Well yes, the motivation in moving to sox in bug 10660 is to support downsampling. We do actually have some seek support for AIFF but I suspect that it is broken if used in conjunction with transcoding, except that when transcoding to FLAC the flac program itself handles the seeking. I wonder why flac chokes on it. The answer is probably just to disable aiff to flac transcoding. How common are AIFF files?
I did not realize that the FLAC binary itself handles the seeking when encoding to FLAC. If I understand you correctly SoX does not have this feature. Could this functionality be added to SoX? Sorry if this is little off topic but it does help me visualize the issue.
Yes, you understand correctly. The flac binary itself handles (or can handle) seeking, when either encoding to flac or decoding from flac, so long as it is the first command in the transcoding pipeline. I do not know whether it would be reasonable to add this to sox.
We are now planning to make a 7.3.3 release. Please review your bugs (all marked open against 7.3.3) to see if they can be fixed in the next few weeks, or if they should be retargeted for 7.4 or future. Thanks!
