Welcome Salim,
Thanks for your interest!
All our samples are recorded in 96 kHz / 24 bit, stored and edited in 96 kHz / 32 bit Floating Point, and are converted to the release format (today this is 44.1 kHz / 24 bit) during the last step in the production cycle, prior to the mapping for the Vienna Instrument. The conversion is done on behalf of a proprietary sampling rate converter which was developed especially for our needs and quality standards. - The data is compressed (NOT reduced) to a proprietary format that allows for unpacking the sample data from the disk in real-time.
Earlier, now discontinued product ranges (First/Pro Edition, Horizon) were released in uncompressed 44.1 kHz /16 bit formats.
HTH,
