Abstract

Methods, apparatus, systems and articles of manufacture are disclosed to identify media that has been pitch shifted, time shifted, and/or resampled. An example apparatus includes: memory; instructions in the apparatus; and processor circuitry to execute the instructions to: transmit a fingerprint of an audio signal and adjusting instructions to a central facility to facilitate a query, the adjusting instructions identifying at least one of a pitch shift, a time shift, or a resample ratio; obtain a response including an identifier for the audio signal and information corresponding to how the audio signal was adjusted; and change the adjusting instructions based on the information.

First claim

What is claimed is:

1. A non-transitory computer readable storage medium comprising instructions which, when executed, cause one or more processors to at least:
transmit a fingerprint of an audio signal and adjusting instructions to an external device to facilitate a query, wherein the adjusting instructions comprise at least one of a pitch shift, a time shift, or a resample ratio;
receive information corresponding to how the audio signal was adjusted; and
store the adjusting instructions for a subsequent query based on the received information.

2. The non-transitory computer readable storage medium of claim 1 , wherein the adjusting instructions are based on a client input.

3. The non-transitory computer readable storage medium of claim 1 , wherein the received information is displayed via a user interface.

4. The non-transitory computer readable storage medium of claim 1 , wherein the instructions further cause the one or more processors to transmit a prompt to a user to identify the adjusting instructions.

5. The non-transitory computer readable storage medium of claim 1 , wherein the instructions further cause the one or more processors to generate the fingerprint from the audio signal.

6. The non-transitory computer readable storage medium of claim 1 , wherein the instructions further cause the one or more processors to transmit a data packet including the received information to a client.

7. The non-transitory computer readable storage medium of claim 1 , wherein the instructions further cause the one or more processors to:
obtain an identifier corresponding to the audio signal from the external device; and
store the identifier and the received information in a database.

8. A method comprising:
transmitting, via a computing device, a fingerprint of an audio signal and adjusting instructions to an external device to facilitate a query, wherein the adjusting instructions comprise at least one of a pitch shift, a time shift, or a resample ratio;
receiving, via the computing device, information corresponding to how the audio signal was adjusted; and
storing, via the computing device, the adjusting instructions for a subsequent query based on the received information.

9. The method of claim 8 , wherein the adjusting instructions are based on a client input.

10. The method of claim 8 , wherein the received information is displayed via a user interface.

11. The method of claim 8 , wherein the method further comprises transmitting a prompt to a user to identify the adjusting instructions.

12. The method of claim 8 , wherein the method further comprises generating the fingerprint from the audio signal.

13. The method of claim 8 , wherein the method further comprises transmitting a data packet including the received information to a client.

14. The method of claim 8 , wherein the method further comprises:
obtaining an identifier corresponding to the audio signal from the external device; and
storing the identifier and the received information in a database.

15. An apparatus comprising:
memory;
instructions in the apparatus; and
one or more processors to execute the instructions to at least:
transmit a fingerprint of an audio signal and adjusting instructions to an external device to facilitate a query, wherein the adjusting instructions comprise at least one of a pitch shift, a time shift, or a resample ratio;
receive information corresponding to how the audio signal was adjusted; and
store the adjusting instructions for a subsequent query based on the received information.

16. The apparatus of claim 15 , wherein the adjusting instructions are based on a client input.

17. The apparatus of claim 15 , wherein the received information is displayed via a user interface.

18. The apparatus of claim 15 , wherein the instructions further cause the one or more processors to transmit a prompt to a user to identify the adjusting instructions.

19. The apparatus of claim 15 , wherein the instructions further cause the one or more processors to generate the fingerprint from the audio signal.

20. The apparatus of claim 15 , wherein the instructions further cause the one or more processors to:
obtain an identifier corresponding to the audio signal from the external device; and
store the identifier and the received information in a database.
