Scoring a match of two audio tracks sets using track time probability distribution
A method and a system are provided for scoring a match of two audio tracks sets using a track time probability distribution. In one example, the system receives the two audio tracks sets, including a first audio tracks set and a second audio tracks set. Next, the system extracts track times of the first audio tracks set and corresponding track times of the second audio tracks set. The system then calculates a total weighted score of the match of the two audio tracks set, wherein the total weighted score is based on a track time probability distribution and a comparison between the track times of the first audio tracks set and the corresponding track times of the second audio tracks set.
1 . A method for scoring a match of two audio tracks sets, the method comprising:
receiving the two audio tracks sets, including a first audio tracks set and a second audio tracks set;
extracting track times of the first audio tracks set and corresponding track times of the second audio tracks set; and
calculating a total weighted score of the match of the two audio tracks set, wherein the total weighted score is based on a track time probability distribution and a comparison between the track times of the first audio tracks set and the corresponding track times of the second audio tracks set.
2 . The method of claim 1 , wherein the calculating a total weighted score comprises at least one of:
calculating time differences between the track times of the first audio tracks set and the corresponding track times of the second audio tracks set; and
calculating weights for the time differences based on the track time probability distribution.
3 . The method of claim 2 , wherein each weight is inversely related to a probability of a particular track time occurring.
4 . The method of claim 2 , further comprising setting each weight based on a degree of rarity of a track time of the particular track comparison according to the track time probability distribution.
5 . The method of claim 2 , further comprising at least one of:
assigning relatively more weight to a particular track comparison if a track of the particular track comparison has a relatively rare time according to the track time probability distribution; and
assigning relatively less weight to a particular track comparison if a track of the particular track comparison has a relatively common time according to the track time probability distribution.
6 . The method of claim 1 , wherein the track time probability distribution is representative of at least one of:
many genres;
one particular genre; and
no genre.
7 . The method of claim 1 , further comprising at least one of:
determining a particular genre of a particular track being compared; and
using a track time probability distribution that is representative of the particular genre.
8 . The method of claim 1 , further comprising at least one of:
determining that the first audio tracks set is a sufficient match to the second audio tracks set;
retrieving metadata for the sufficient match from a albums database; and
sending the metadata to a user computer.
9 . The method of claim 1 , further comprising at least one of:
determining that the first audio tracks set is a sufficient match to the second audio tracks set;
retrieving metadata for the sufficient match from a local albums database of a user computer; and
displaying the metadata on the user computer.
10 . The method of claim 1 , wherein the extracting the track times comprises at least one of:
reading from a table of contents of the first audio tracks set; and
reading from a table of contents of the second audio tracks set.
11 . A system for scoring a match of two audio tracks sets, wherein the system is configured for:
receiving the two audio tracks sets, including a first audio tracks set and a second audio tracks set;
extracting track times of the first audio tracks set and corresponding track times of the second audio tracks set; and
calculating a total weighted score of the match of the two audio tracks set, wherein the total weighted score is based on a track time probability distribution and a comparison between the track times of the first audio tracks set and the corresponding track times of the second audio tracks set.
12 . The system of claim 11 , wherein the calculating a total weighted score comprises at least one of:
calculating time differences between the track times of the first audio tracks set and the corresponding track times of the second audio tracks set; and
calculating weights for the time differences based on the track time probability distribution.
13 . The system of claim 12 , wherein each weight is inversely related to a probability of a particular track time occurring.
14 . The system of claim 12 , wherein the system is further configured for setting each weight based on a degree of rarity of a track time of the particular track comparison according to the track time probability distribution.
15 . The system of claim 12 , wherein the system is further configured for at least one of:
assigning relatively more weight to a particular track comparison if a track of the particular track comparison has a relatively rare time according to the track time probability distribution; and
assigning relatively less weight to a particular track comparison if a track of the particular track comparison has a relatively common time according to the track time probability distribution.
16 . The system of claim 11 , wherein the track time probability distribution is representative of at least one of:
many genres;
one particular genre; and
no genre.
17 . The system of claim 11 , wherein the system is further configured for at least one of:
determining a particular genre of a particular track being compared; and
using a track time probability distribution that is representative of the particular genre.
18 . The system of claim 11 , wherein the system is further configured for at least one of:
determining that the first audio tracks set is a sufficient match to the second audio tracks set;
retrieving metadata for the sufficient match from a albums database; and
sending the metadata to a user computer.
19 . The system of claim 11 , wherein the system is further configured for at least one of:
determining that the first audio tracks set is a sufficient match to the second audio tracks set;
retrieving metadata for the sufficient match from a local albums database of a user computer; and
displaying the metadata on the user computer.
20 . The system of claim 11 , wherein the extracting the track times comprises at least one of:
reading from a table of contents of the first audio tracks set; and
reading from a table of contents of the second audio tracks set.
21 . A computer readable medium carrying one or more instructions for scoring a match of two audio tracks sets, wherein the one or more instructions, when executed by one or more processors, cause the one or more processors to perform the steps of:
receiving the two audio tracks sets, including a first audio tracks set and a second audio tracks set;
extracting track times of the first audio tracks set and corresponding track times of the second audio tracks set; and
calculating a total weighted score of the match of the two audio tracks set, wherein the total weighted score is based on a track time probability distribution and a comparison between the track times of the first audio tracks set and the corresponding track times of the second audio tracks set.
