Hi,
I have taken libtremor (latest from tree). I have built it with ivorisfile_exaple.c for windows. I used these test vecotrs to check http://people.xiph.org/~xiphmont/test-vectors/vorbis/ tremor output against
Vorbis floating point decoder output. I compared both the results [tremor vs vorbis float point]. Below is the summary of the results.
I am not sure whether input test vectors, which i used, are correct one. I am not also sure about the behaviour of tremor decoder against Vorbis float decoder.
Please suggest if the results are acceptable.
