22 // This class derives from AliAltroBuffer, but overloads the memer
23 // function Next to do some extra processing. In particular, it tries
24 // to autodetect the sample rate. If zero-suppression was used when
25 // writing the raw data, then the automatic discovery will not work,
26 // and the sample rate should be set explicitly.
