Hi all,

I was doing audio transcoding using AudioConverterFillcomplexBuffer in
which I found that the length of the transcoded wave file is different
than the source mp3 file.
I amalso providing the screenshots which is taken by using Quicktime
Inspector for these files.

Can anybody tell this. Although the length is approximately same but
can make significant difference if data is received from stream,
transcoded and restreamed from the transcoded data.

Also there are lots of zero bytes in the begining of the data chunk in
the transcoded RIFF-WAVE. I also reported this earlier but no concrete
response on this.

Any guesses???
