## What is Melody Extractor?

some reviews says the melody extractor generates midi in random, it maybe the previous model's limitation, while we do never generate midi randomly, all midi data is from AI's prediction. 

Train a great model is not very easy, if the model is not good enough, the data from model's prediction may make people feel it like generated randomly.

Now, we had taken a new neural network method, and trained a new good model, thanks for TensorFlow making it much quicker and easier.

You could extract the melody from any music or even voice by using our melody extractor.

Singing a song, then extract the melody, export the midi file, it will even make your music creation more easier.

Though we try to use the newest and the best model to extract melody from music, AI could not duplicate the song's original staff melody anyway, AI can only keep a probably notes for midi, and some notes maybe wrong.

We do not promise you get the perfect melody for each song, maybe one song's melody is very good, while another song's melody is a little bad. The results depends on the song's melody itself, if the song's melody is similar with the AI model's trained data, the result will be very good, if not, the result will be a little bad.

Anyway, it's worth you have a try, melody extractor will help you get pure melody from any music more simple.

Notes: there's two common reason for this app's crash, one is the music file too large, maybe too long, this will make memory out of usage, we should not consider it as a bug, the mobile device has limitation on memory itself, we could use audio trim tools to clip the audio, try to make the audio file smaller size, then it should be ok for processing to extract the melody. And another reason is midi player crash, as we use the piano file embedded into app, some notes may be lack of, so we should not rely on this app to play midi file, we should consider to export the midi file to computer, and let the midi software on computer to play the midi file.

Surely, for most of music files, these two issues should not happen, as most of music files is not very long, and the embedded piano file should be enough to play most midi file.

### What is Melody Extractor?

Melody Extractor is a utility app that uses AI to extract the main melody from any music or voice recording and convert it into a MIDI file. This allows for easier integration into music creation workflows.

### How accurate is Melody Extractor?

The accuracy of Melody Extractor depends on the complexity of the song's melody and its similarity to the AI model's training data. While it aims for precise melody extraction, AI predictions may sometimes result in minor inaccuracies or variations in the MIDI output.

### Can Melody Extractor extract melodies from singing?

Yes, you can sing a song and use Melody Extractor to extract the melody. The app then exports this as a MIDI file, which can be used to further enhance your music creation process.

### What are the limitations of Melody Extractor?

Very large or long music files can cause memory issues and app crashes due to device limitations. It's recommended to trim audio files to a smaller size. Additionally, the embedded MIDI player within the app may have limitations, and it's best to export MIDI files for playback on computer software.

## Version history (last 4 releases)

### 4.3.0 — 2024-04-19

add a user controllable midi velocity
the default value for midi velocity is 120, it is the best value for model, while in processing, with input midi file different, adjusted velocity will make a better extracted melody
In one word, higher the velocity value, the melody extracted will be faster when play.

### 4.1.0 — 2023-05-14

improve accuracy for extracting melody from any music
use a new , better TensorFlow model to predict data 
add a new localization - English
the text description on AI's process more concrete and accuracy

### 3.0.1 — 2021-11-10

优化了模型的预测
对钢琴曲的MIDI转换比之前更加精确
更改了部分算法
对于一般音乐的转换MIDI仍有局限性
模型是基于大量钢琴曲进行训练的，虽然可以用于一般音乐预测，但是对于复杂混声的音乐预测转换效果明显不太理想
建议使用电脑库乐队播放转换的MIDI文件，播放效果比手机直接播放要好很多

### 2.0.1 — 2021-09-09

No release notes.
