Bugzilla – Bug 1508
flac files made by dbpoweramp don't play properly (massive distortion)
Last modified: 2008-12-18 11:37:19 UTC
customer reported, i have a sample file but it may be too large to attach to the bug. everything looks fine in the encoding, it's not using an odd blocksize or anything (it's using 4608, which is the same as all of my flac files on my linux machine at home)... but this file will not play. as a workaround i recommended disabling the FLAC->FLAC/built-in transcoding rule, and the files play fine when using the flac decoder included with the server... the vorbis tag looks like such: TITLE=Short Order ARTIST=Alex De Grassi ALBUM=Deep at Night DATE=1991 GENRE=New Age# ENCODEDBY=FairStars Audio Converter TRACKNUMBER=4
also when stringsing the file it says: reference libFLAC 1.1.1 20041001
Created attachment 496 [details] flac file that won't play properly
does FLAC encode in both byte orders?
vidur to listen to this file.
No, FLAC uses a canonical byte order. The only difference I see between the attached file and other ones that play correctly are higher precision and quantization for quantized linear-prediction coefficients (these values are generally left up to the flac encoder, by specificable during encoding using the -q or --qlp-coeff-previcision option). Other than that, the analysis file of the attached track (generated using flac -a) doesn't seem that remarkable.
Fixed with firmware 15.
