Hello: I have a client that has both a DAT tape format and VHS tape format that was used for logging audio at a call center. I am not familiar with either of these formats being used for call logging. Can anyone out there provide some insight as to the types of machines used for this purpose? Also the project mandates that the audio, as it is captured or after capture, is encrypted for security reasons. I have not had to do this as part of a digitization process. Can someone point me in the right direction to some potential programs one would use to do this? I'm assuming there is no such thing as "open sourced" encryption programs and that they are all proprietary, which is the inverse of what archiving this data is all about because if the company that provides the encryption software goes out of business and there is no support, the files then become useless. Does anyone with experience have any thoughts on this? At present, the client is indicating that each individual file has to be encrypted, it's not a situation where the storage media container such as the drive itself that the files are sitting on could be encrypted. Any insight would be most appreciated. Kind Regards, John Schroth
