Issue 2 (skipped notes)įrom, , Section 6 'Need for more data, more rigorous evaluation': In addition, synthesized audio makes up a large fraction of the MAPS dataset. “performances” are not as natural as the MAESTRO performances captured from live performances. Issue 1 (small dataset and not as natural) Not used datasets Not used: MAPS (from Fichiers - Aix-Marseille Université) Or see more detailed instructions here:įor some samples last midi note onsets are slightly beyond the duration of the corresponding WAV-audio. And do not forget to add the 'PATH' environment variable with the location of your downloaded 'ffmpeg.exe'.

If Python 'Librosa' module cannot open any audio format except WAV, download FFmpeg codec:Ĭhoose your Windows architecture and static linking there.

So, eventually, in the third IPython template, instead of training my own model, I just copied the weights from the Google's pre-trained tensorflow checkpoint: But my resultant accuracy was slightly less, probably because of the reduced batch size. Just for fun, I blindly copied those model parameters, and trained the model in the second IPython template. There is Google's model called 'Onsets & Frames' with very good accuracy, see the following blog post: The previous full Tensorflow model (not TensorFlow Lite) is used in my app for Windows 7 or later, to see it click on the following screenshot: To see my app for Android 4.4 KitKat (API level 19) or higher, click on the following screenshot: This model is super-fast on my Android device and accuracy is still not bad. There is an example of using the model in my fifth IPython template ('5 TF Lite Inference.ipynb'). It takes as input approximately 1 second of raw audio (not 20 seconds of mel spectrogram). Or look for the link in the GitHub-repository: There is another pre-trained Magenta's model in TensorFlow Lite format, it can be downloaded here: The accuracy will depend on the complexity of the song, and will obviously be higher for solo piano pieces. IPython-notebook templates for neural network training and then using it to generate piano MIDI-files from audio (MP3, WAV, etc.).
