Hi all, I have a decent media PC, win7 RME 9652 sound card, and after a lot of advice from folk I use j river media player. People advise using wasapi event driver, but on checking asio, kernel streaming and wasapi, I found asio a bit soft, wasapi a bit bright and ks is just right.
I wondered about if there were measurable differences in the spdif data. Initially tried to capture to a creative x-fi ti on same machine, but lot of audible glitches. Then went into a lexicon omega capturing at 44/16 ( as per the source file). Tried analysis using fourierrocks, but a lot software problems. Then used another program to write out the wav files as text files. Moved to excel, and lined up the files.
It is by no means bit identical! One of the samples (the 1st one using asio) has lots of visible differences, but the other three (asio(control), ks, wasapi) all visibly overlay, but at the bit level there are difference.
What are the differences... It looks like the data is time shifted slightly. I could understand this if the omega resampled the data, but I thought that the digital transfer your simple sample the bit as they are, so with the odd error here and there some noise, but not time shifted slightly (by the way, i'm talking about less than 1/44k sec shift).
Anyone got ideas... I can upload the data to dropbox so others can look...
Cheers,
