The only way to experience real HD-Audio files is to get some and take a listen. I have set up an FTP site with a number of sample files that you are welcome to download and audition. There is a pdf document that describes the tracks and includes the spectragraphs for comparison. If you would like to receive the credentials for our FTP site, please provide us with your email address. Your email will be added to our mailing list unless you request otherwise. I’m always interested in feedback.
