wav-to-midi conversion -

-

I'm new to this area - but I need to convert to a WAV-to-MIDI conversion in Java. I want WAV- Is there a way to actually know the steps involved in to-MIDI conversions? I have a very difficult idea as you would like; Sample wav file, filter it, spectral analysis, use FFT for feature extraction and then write the features extracted on the media. But I have not found a solid source or paper, how to do it all? Does anyone tell me how and where to start? Is there an open source API available for this open-to-midi conversion process?

In advance thanks

It is a more complex process than you imagine .

The problem of this research is often referred to as the music transcription : the task of converting low-level representations of music (i.e., wave) to high- Level representation or even sheet music.

The sophistication of your solution will depend on the complexity of your input data Tons of research papers only monophonic piano or the diagnosis of transcription of music on the drum ... because they are easily transcription (relatively.) Violin hard Voice is tough too, violin plus voice plus piano is very hard. A symphony is almost impossible you get the picture.

The basic elements of the music transcription include the following overlapping areas:

  1. (multi) pitch estimates
  2. Device identification
  3. Note / Offset Detection
  4. Form / Structure Modeling

Search the document on Google Scholar or "Music Transcription" with ISMIR Proceedings: If you are interested in one of the above sub-topics, then I can tell you further. Best wishes

EDIT: This is being said, there are existing solutions that we can all find on the web, feel free to try them but as you do, they have an important eye and ears Evaluate with Audio Signal What type of transcription would be the reason for failure? Edit 2: Ah, you are doing this just for the piano, it is possible that the music transcription has increased to that point where it can very well write monophonic piano a Rachmaninov concerto will still create problems.

Our recommendations depend on our end goal. You need to java .... So it seems that you want something to work, even if you find it there. In that case, I agree with others 100%: use something that exists

This is really an interesting question; I know that all MIR libraries generally have C / C ++ / Python / Metlab but I have no Java encoding in the Java encoding, but I do not think it does note-level transcription. (Edit: It does note-level transcription. The data returned includes pitch, timber, beet, trump and more. But I still have a problem to detect polyponi.) < / P>

, Marcia is Java based cool. I thought it was just C ++. I recommend it is developed by a professor in George Tzanetakis, MIR. It does signal-level analysis and should be a good choice.

Now, if this is for a fun learning experience, then I think you can use sound manipulation utilities in Java to experiment with the WAV signal and see what comes up.

EDIT: This page can tell MIR software as well as I can:

For Matlab, you may be interested in it

Here's a good one General dataset page:

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'

Just ask someone to solve this problem? I want to create a multilevel menu I can not find the right solution generated with multilevel array, it always gets an array_push error My study came from the original idea But still my Can not match the need.
