Matching method and system for audio content

An audio content matching system, comprising:

• an audio frame obtaining unit, configured to obtain a first audio frame and a second audio frame from an audio clip to be matched, wherein the first audio frame and the second audio frame are audio frames in successive;
• a sub-band converting unit, configured to separately convert the first audio frame and the second audio frame from the audio frame unit into a first group of sub-bands and a second group of sub-bands;
• a sub-hash table converting unit, configured to separately convert the first group of sub-bands and the second group of sub-bands from the sub-bands converting unit into a first group of sub-hash tables and a second group of sub-hash tables;
• a candidate audio obtaining unit, configured to separately compare the first group of sub-hash tables and the second group of sub-hash tables of the sub-hash table converting unit with the audio clips stored in a database and obtain a first group of candidate audio and a second group of candidate audio;
• and
• a matching result selecting unit, configured to determine a matching result by selecting from the first group of candidate audio and the second group of candidate audio.

A non-transitory computer readable storage medium, storing one or more programs for execution by one or more processors of a computer having a display, the one or more programs comprising instructions for:

• obtaining a first audio frame and a second audio frame from an audio clip to be matched, wherein the first audio frame and the second audio frame are audio frames in successive;
• converting the first audio frame into a first group of sub-bands and converting the second audio frame into a second group of sub-bands;
• converting the first group of sub-bands into a first group of sub-hash tables and converting the second group of sub-bands into a second group of sub-hash tables;
• separately comparing the first group of sub-hash tables and the second group of sub-hash tables with the audio clips stored in a database and obtaining a first group of candidate audio and a second group of candidate audio;
• and
• determining a matching result by selecting from the first group of candidate audio and the second group of candidate audio.
