Selecting pitch lag

There are proposed techniques (e.g., in apparatus, methods, programs) for selecting pitch lag. An apparatus (10, 60a, 110) for encoding an information signal including a plurality of frames. The apparatus may comprise a first estimator (11) configured to obtain a first estimate (14, Ti), the first e...

Zusammenfassung:	There are proposed techniques (e.g., in apparatus, methods, programs) for selecting pitch lag. An apparatus (10, 60a, 110) for encoding an information signal including a plurality of frames. The apparatus may comprise a first estimator (11) configured to obtain a first estimate (14, Ti), the first estimate being an estimate of a pitch lag for a current frame (13). The apparatus may comprise a second estimator (12) configured to obtain a second estimate (16, T2), the second estimate being another estimate of a pitch lag for the current frame (13). A selector (17) may be configured to choose (S103) a selected value (19, T
