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 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.
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 a facility to facilitate a query, the adjusting instructions identifying at least one of a pitch shift, a time shift, or a resample ratio;
obtain information corresponding to how the audio signal was adjusted; and
modify the adjusting instructions for a subsequent query based on the information.
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 instructions cause the one or more processors to generate the fingerprint from the audio signal.
5. The non-transitory computer readable storage medium of claim 1 , wherein the information can be displayed on a user interface.
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. The non-transitory computer readable storage medium of claim 1 , wherein the instructions cause the one or more processors to:
obtain an identifier corresponding to the audio signal from the facility; and
store the identifier and the information in a database.
8. An apparatus comprising:
memory;
instructions in the apparatus; and
processor circuitry to execute the instructions to at least:
transmit a fingerprint of an audio signal and adjusting instructions to a central facility to facilitate a query, the adjusting instructions identifying how the audio signal may be adjusted; and
receive a response including an identifier for the audio signal and information corresponding to how the audio signal was adjusted; and
an application to adjust the adjusting instructions for a subsequent query based on the information.
9. The apparatus of claim 8 , further including a user interface to display a prompt to a user to identify the adjusting instructions.
10. The apparatus of claim 8 , wherein the adjusting instructions are defined by a client.
11. The apparatus of claim 8 , wherein the instructions cause the processor circuitry to transmit a data packet including the information to a client.
12. The apparatus of claim 8 , further including a user interface to display the information to a user.
13. The apparatus of claim 8 , wherein the information is used to modify the adjusting instructions for a subsequent fingerprint identification.
14. The apparatus of claim 8 , further including a fingerprint generator to generate the fingerprint from the audio signal.
15. The apparatus of claim 8 , wherein the instructions cause the processor circuitry to store the identifier and the information in a database.
16. An apparatus comprising:
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.
17. The apparatus of claim 16 , wherein the processor circuitry is to cause display of a prompt to a user to identify the adjusting instructions.
18. The apparatus of claim 16 , wherein the adjusting instructions are defined by a client.
19. The apparatus of claim 16 , wherein the processor circuitry is to transmit a data packet including the information to a client.
20. The apparatus of claim 16 , wherein the processor circuitry is to cause a display of the information to a user.
