Methods and apparatus to identify media that has been pitch shifted, time shifted, and/or resampled
Methods, apparatus, systems and articles of manufacture are disclosed to identify media that has been pitch shifted, time shifted, and/or resampled. An example method includes: generating, by executing an instruction with a processor, a fingerprint from an audio signal; transmitting the fingerprint and adjusting instructions to a central facility to facilitate a query, the adjusting instructions identifying at least one of a pitch shift or a time shift; and receiving a response including an identifier for the audio signal and information corresponding to how the audio signal was adjusted; storing information indicative of the identifier and the information into a database.
1. A non-transitory computer readable storage medium comprising instructions which, when executed, cause one or more processors to at least:
generate a fingerprint from an audio signal;
transmit the fingerprint 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;
receive a response including an identifier for the audio signal and information corresponding to how the audio signal was adjusted; and
store information indicative of the identifier and the information into a database.
2. The non-transitory computer readable storage medium of claim 1 , wherein the instructions cause the one or more processors to transmit a prompt to a user to identify the adjusting instructions.
3. The non-transitory computer readable storage medium of claim 1 , wherein the adjusting instructions are defined by a client.
4. The non-transitory computer readable storage medium of claim 1 , wherein the information can be displayed on a user interface.
5. The non-transitory computer readable storage medium of claim 1 , wherein the instructions cause the one or more processors to modify the adjusting instructions based on the information for a subsequent fingerprint identification.
6. The non-transitory computer readable storage medium of claim 1 , wherein the instructions cause the one or more processors to transmit a data packet including the information to a client.
7. An apparatus comprising:
a fingerprint generator to generate a fingerprint from an audio signal; and
a network interface to:
transmit the fingerprint and adjusting instructions to a central facility to facilitate a query, the adjusting instructions identifying at least one of a pitch shift or a time shift;
receive a response including an identifier for the audio signal and information corresponding to how the audio signal was adjusted; and
store information indicative of the identifier and the information into a database, at least one of the fingerprint generator or the network interface including hardware.
8. The apparatus of claim 7 , further including a user interface to display a prompt to a user to identify the adjusting instructions.
9. The apparatus of claim 7 , wherein the adjusting instructions are defined by a client.
10. The apparatus of claim 7 , wherein the network interface is to transmit a data packet including the information to a client.
11. The apparatus of claim 7 , further including a user interface to display the information to a user.
12. The apparatus of claim 7 , wherein the information is used to modify the adjusting instructions for a subsequent fingerprint identification.
13. A method comprising:
generating, by executing an instruction with a processor, a fingerprint from an audio signal;
transmitting the fingerprint and adjusting instructions to a central facility to facilitate a query, the adjusting instructions identifying at least one of a pitch shift or a time shift;
receiving a response including an identifier for the audio signal and information corresponding to how the audio signal was adjusted; and
storing information indicative of the identifier and the information into a database.
14. The method of claim 13 , further including transmitting a prompt to a user to identify the adjusting instructions.
15. The method of claim 13 , wherein the adjusting instructions are defined by a client.
16. The method of claim 13 , further including transmitting the information as a data packet to a client.
17. The method of claim 13 , further including displaying the information to a user.
18. The method of claim 13 , wherein the information is used to modify the adjusting instructions for a subsequent fingerprint identification.
19. An apparatus comprising:
memory;
instructions in the apparatus; and
processor circuitry to execute the instructions to:
generate a fingerprint from an audio signal;
transmit the fingerprint and adjusting instructions to a central facility to facilitate a query, the adjusting instructions identifying at least one of a pitch shift or a time shift;
receive a response including an identifier for the audio signal and information corresponding to how the audio signal was adjusted; and
store information indicative of the identifier and the information into a database.
20. The apparatus of claim 19 , wherein the processor circuitry is to cause display of a prompt to a user to identify the adjusting instructions.
21. The apparatus of claim 19 , wherein the adjusting instructions are defined by a client.
22. The apparatus of claim 19 , wherein the processor circuitry is to transmit a data packet including the information to a client.
23. The apparatus of claim 19 , wherein the processor circuitry is to cause a display of the information to a user.
24. The apparatus of claim 19 , wherein the information is used to modify the adjusting instructions for a subsequent fingerprint identification.
