A descriptive term for an encoded signal, as in a NR system. Sometimes used to describe the signal after subsequent decoding. In film, a stretched transfer involved making a new recording of an encoded recording without decoding, and then re-encoding the material. In this way, a stretched transfer retains the original noise reduction encoding level. It is not recommended to do the transfer on a decoded version because any response error is multiplied by the compression ratio, typically 2:1, of the noise reduction system.
