Signal processing arrangement and method with adaptable signal reproduction rate

A signal processing method, comprising:

• supplying signal data of a stored signal that is defined relative to a signal time base;
• processing the signal data to adapt a reproduction rate to an adapted time base, with an adaptable time rate relative to the signal time base;
• passing samples of the signal with adapted reproduction rate through a delaying buffer and rendering the signal that emerges from the buffer;
• signaling commands to change said rate;
• controlling the rate used for reproduction rate adaptation based on a last preceding accepted one of the commands,
• storing information for at most a predetermined number of the accepted ones of the commands;
• detecting when effects of the accepted ones of the commands emerge from the delaying buffer;
• and
• disabling acceptation of further ones of the commands when information for said predetermined number of accepted ones of the commands is stored, until said detecting indicates said emergence for at least one of the commands for which the information is stored.

A computer program product, comprising instructions for a programmable computer that, when executed by the computer, cause the computer to

• receive commands to change a reproduction rate defining an adapted time base with an adaptable time rate relative to an original signal time base;
• control a rate used for reproduction rate adaptation based on a last preceding accepted one of the commands,
• store information for at most a predetermined number of the accepted ones of the commands;
• detect when effects of the accepted ones of the commands emerge from a delaying buffer;
• and
• disable acceptation of further ones of the commands when information for said predetermined number of accepted ones of the commands is stored, until detection indicates said emergence from the delaying buffer of the effect for at least one of the commands for which the information is stored.
