7684b53c | 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. | |
