MERKMAL-BASIERTE AUDIO-INHALTSIDENTIFIKATION |
| 摘要 |
Audio is analyzed based on semitone intervals (402-406) and an average is calculated for each semitone channel (408-410). Running averages are calculated for each semitone channel (412) and averages are compared to see if they cross (414, 416). Crossing events are marked and utilized in combination with frequency spectrum data to determine a match between stored sound patterns and the input audio. |
