Abstract

The invention relates to a method for setting audio parameters in a digital signal processor in an electronic device including at least one auxiliary device connection for connecting at least one auxiliary device. At least some of the audio parameters can be loaded into the digital signal processor during operation of the electronic device either from the auxiliary device or from a writeable mass storage.

Claims

1. A method comprising:

loading at least one audio parameter that controls processing in a digital signal processor from an auxiliary device into the digital signal processor, said at least one audio parameter being loaded from the auxiliary device via an auxiliary device connection, said digital signal processor configured to use said at least one audio parameter during operation of at least one other device when the auxiliary device is connected to the at least one other device so that said at least one audio parameter controls the processing of one or more audio signals transferred between the auxiliary device and the at least one other device via the auxiliary device connection, wherein the processing of the one or more audio signals is controlled in the digital signal processor dependent on said at least one audio parameter specifically for the auxiliary device during operation of the at least one other device when connected to the auxiliary device;

said loading comprising communicating digital data between the at least one other device and a controller in said auxiliary device.

2. The method according to claim 1, further comprising loading the audio parameters at a stage when the auxiliary device is connected to or detached from the at least one other device or when the auxiliary device changes its audio mode.

3. The method according to claim 2, said loading further comprising instructing the at least one other device to transmit a command to a controller of the auxiliary device to send at least one audio parameter to the other device.

4. The method according to claim 1, wherein said audio parameter is other than data used to recognize the type of auxiliary device.

5. The method according to claim 1, wherein said at least one audio parameter is loaded into the digital signal processor from the auxiliary device.

6. An apparatus comprising:

a digital signal processor configured to process audio signals;

an interface configured to use at least one audio parameter that controls the processing of audio signals in the digital signal processor, said at least one audio parameter relating to audio properties of an auxiliary device when connected to at least one other device; and

a communication interface configured to communicate with a controller of said auxiliary device to load said at least one audio parameter from the auxiliary device to said interface and to use said at least one audio parameter during operation of the other device when the auxiliary device is connected to the other device, said communication interface being configured to conduct communication of digital data between said controller of the auxiliary device and said apparatus so that said at least one audio parameter controls the processing of one or more audio signals transferred between the auxiliary device and the other device via the communication interface, wherein the processing of the one or more audio signals is controlled in the digital signal processor dependent on said at least one audio parameter specifically for the auxiliary device during operation of the other device when connected to the auxiliary device.

7. The apparatus according to claim 6, further comprising an input device configured to detect a connection of the auxiliary device to the other device.

8. The apparatus according to claim 7, wherein the input device is further configured to provide a detection data signal indicative of the connection of the auxiliary device to the at least one other device.

9. The apparatus according to claim 6, wherein the apparatus comprises a transmitter/receiver unit of a mobile station.

10. The apparatus according to claim 6, wherein said at least one audio parameter is other than data used to recognize the type of auxiliary device.

11. The apparatus according to claim 6, wherein said at least one audio parameter is loaded into the digital signal processor from the auxiliary device.

12. The apparatus according to claim 6, wherein said communication interface is configured to transmit a command to the controller of the auxiliary device to send at least one audio parameter from the auxiliary device to the apparatus.

13. The apparatus according to claim 6 comprising a memory configured to store said at least one audio parameter loaded from the auxiliary device.

14. An apparatus comprising:

a digital signal processor configured to process audio signals;

an interface configured to use at least one audio parameter that controls the processing of audio signals in the digital signal processor, said at least one audio parameter relating to audio properties of an auxiliary device when connected to the apparatus; and

a communication interface configured to communicate with a controller of said auxiliary device to load said at least one audio parameter from the auxiliary device to said interface and to use said at least one audio parameter during operation of the apparatus when the auxiliary device is connected to the apparatus, said communication interface being configured to conduct communication of digital data between said controller of the auxiliary device and said apparatus so that said at least one audio parameter controls the processing of one or more audio signals transferred between the auxiliary device and the apparatus via the communication interface, wherein the processing of the one or more audio signals is controlled in the digital signal processor dependent on said at least one audio parameter specifically for the auxiliary device during operation of the apparatus when connected to the auxiliary device.

15. The apparatus according to claim 14, wherein said communication interface is configured to transmit a command to the controller of the auxiliary device to send at least one audio parameter from the auxiliary device to the apparatus.
