StartFromFileEncrypted method

Previous pageReturn to chapter overviewNext page

Remarks

 

Starts a new recording session from an input sound file that was previously encrypted through the EncryptCurrentSession method or through the CryptSound™ application.

 

During the recording sessions the container application is notified through the CallbackForRecordersEvents delegate which is invoked with the nEvent parameter set to EV_REC_START at the beginning and to EV_REC_STOP at the end. The current percentage of advancement is notified through the EV_REC_PERC event.

 

For details about encryption/decryption features see the How to protect your recording sessions through encryption tutorial.
