The algorithm recognizes and gives you list of notes with their startTime/duration information. Any digital audio workstations can read such .midi files.\n\n## Example\n\n**Input:** [RiversFlowInYou.wav](https://github.com/artemik/notes-recognizer/blob/master/example/RiversFlowInYou.wav)\n\n**Output:** [RiversOut1400.midi](https://github.com/artemik/notes-recognizer/blob/master/example/RiversOut1400.midi)\n\n![Main window](https://github.com/artemik/notes-recognizer/blob/master/example/Main.jpg)\n\nThe current alghotihm is pretty weak. But anyway you can test the application with an example file RiversFlowInYou.wav that you can find in the example folder and check out a nice result. But, I've found out very interesting approaches recently. That's why a very strong algorithm is on the way! This includes \u003cb\u003eHidden Markov Models\u003c/b\u003e, \u003cb\u003eMFCC\u003c/b\u003e and clusterization. I'll publish it very soon. Stay tuned!\n\nYou need \u003ca href=\"http://xmlgraphics.apache.org/\" target=\"_blank\"\u003exmlgraphics\u003c/a\u003e to compile the project.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fartemik%2Fnotes-recognizer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fartemik%2Fnotes-recognizer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fartemik%2Fnotes-recognizer/lists"}
