  • Publication number: 20160314802
    Abstract: A volume controlling method and a volume controlling device reduce volume adjustment delay. The method includes acquiring a smooth volume and smooth envelope of a signal sampling point at the current moment. An autocorrelation value of the smooth envelope is determined within a first time period and the smooth envelope within each second time period according to the smooth envelope at the current moment and multiple pre-stored smooth envelopes at historical moments. The autocorrelation value having the maximal numerical value is determined from the determined respective autocorrelation values as the maximal autocorrelation value. A combined smooth volume at the current moment is determined according to the smooth volume at the current moment and the maximal autocorrelation value. A volume gain is determined according to the combined smooth volume and a predetermined reference volume. The volume of a voice signal is controlled according to the volume gain at the current moment.

  • Patent number: 8732126
    Abstract: A method and apparatus for capturing database system workload and replaying that workload in a database system is provided. According to one aspect, in order to subject a test database system to the same workload to which the production database system actually would be subjected, a database server in the production system captures and records workload that the database server receives from external entities. This captured workload is processed. Processes external to a database server in the test database system send the processed workload to that database server. As a result, the test database system is subjected to the same workload to which the production database system originally was subjected. The foregoing technique permits a database administrator to determine how the production database system will fare if the difference that is present in the test database system is introduced into the production database system.
