| Abstrakt: | Systems and methods for payload encoding and decoding are disclosed. An example apparatus includes a processor. The example apparatus further includes a storage device in communication with the processor, the storage device including instructions which, when executed, cause the processor to at least process a license file to obtain information to access a message encoded in audio, the information obtained from the license file including at least one of decoding information, message codes, a decoding algorithm or diagnostic information; detect the message encoded in the audio based on the information obtained from the license file; and output the detected message. |

| Claim: | 1. An apparatus to decode audio, the apparatus comprising: a processor; and a storage device in communication with the processor, the storage device including instruction which, when executed, cause the processor to at least: process a license file to obtain information to access a message encoded in audio, the information obtained from the license file including at least one of decoding information, message codes, a decoding algorithm or diagnostic information; detect the message encoded in the audio based on the information obtained from the license file; and output the detected message. |
| Claim: | 2. The apparatus of claim 1 , wherein the processor is to examine peak accumulated symbol values and relative timing associated with the peak accumulated symbol values to detect the message. |
| Claim: | 3. The apparatus of claim 1 , wherein the processor is to send, to an operator of an encoding system associated with encoding the message in the audio, (A) identifying information for a client device associated with the processor and (B) identifying information for a session in which the audio is to be received. |
| Claim: | 4. The apparatus of claim 1 , wherein the processor is to process the license file to obtain at least one of (A) data defining the message, a symbol, and a code tone frequency used to perform the decode algorithm, (B) information defining a process step to determine if the audio includes embedded message codes, or (C) an encrypted decoding information byte array that defines layers, message structures, and symbol durations for decoding the audio. |
| Claim: | 5. The apparatus of claim 1 , wherein the processor is to: process the license file to obtain a hash key linked to commands, the commands stored in the storage device; and unlock the commands using the hash key. |
| Claim: | 6. The apparatus of claim 1 , wherein the processor is to: install a shared library in the storage device; and install encrypted decoding information in the storage device, the shared library not to process a decryption key for the encrypted decoding information. |
| Claim: | 7. The apparatus of claim 6 , wherein the processor is to provide the license file to a data server to request the decryption key and is to decrypt the encrypted decoding information using the decryption key, the shared library to produce a stream of symbol values using the decrypted decoding information. |
| Claim: | 8. The apparatus of claim 1 , wherein the processor is to: produce a stream of symbol values for each code symbol included in the audio; accumulate the stream of symbol values in the storage device; and detect a presence of the encoded message based on the stream of symbol values. |
| Claim: | 9. The apparatus of claim 8 , wherein the processor is to detect match the accumulated stream of symbol values to stored patterns to detect the message. |
| Claim: | 10. A method to decode audio, the method comprising: processing, by executing an instruction with a processor, a license file to obtain information to access a message encoded in audio, the information obtained from the license file including at least one of decoding information, message codes, a decoding algorithm or diagnostic information; detecting, by executing an instruction with the processor, the message encoded in the audio based on the information obtained from the license file; and outputting the detected message. |
| Claim: | 11. The method of claim 10 , wherein the detecting of the message includes examining peak accumulated symbol values and relative timing associated with the peak accumulated symbol values to reconstruct the message. |
| Claim: | 12. The method of claim 10 , further including sending, to an operator of an encoding system associated with encoding the message in the audio, (A) identifying information for a client device associated with the processor and (B) identifying information for a session in which the audio is to be received. |
| Claim: | 13. The method of claim 10 , wherein the processing of the license file includes obtaining at least one of (A) data defining the message, a symbol, and a code tone frequency used to perform the decode algorithm, (B) information defining a process step to determine if the audio includes embedded message codes, or (C) an encrypted decoding information byte array that defines layers, message structures, and symbol durations for decoding the audio. |
| Claim: | 14. The method of claim 10 , wherein the processing of the license file includes obtaining a hash key linked to commands, the commands stored in a storage device, and further including unlocking the commands with the processor using the hash key. |
| Claim: | 15. The method of claim 10 , further including: installing a shared library in a storage device; and installing encrypted decoding information into the storage device, the shared library not to possess a decryption key for the encrypted decoding information. |
| Claim: | 16. The method of claim 15 , further including: providing the license file to a data server to request the decryption key; and decrypting the encrypted decoding information using the decryption key, the shared library to produce a stream of symbol values using the decrypted decoding information. |
| Claim: | 17. The method of claim 10 , further including: producing a stream of symbol values for each code symbol included in the audio; and accumulating the stream of symbol values in a storage device, the detecting of the message including detecting a presence of the encoded message based on the stream of symbol values. |
| Claim: | 18. The method of claim 17 , wherein the detecting of the message includes matching the accumulated stream of symbol values to stored patterns. |
