YouTube video to chords, lyrics, beat and melody.
A transformer-based hybrid multimodal model, various transformer models address different problems in the field of music information retrieval, these models generate corresponding information dependencies that mutually influence each other.
An AI-powered multimodal project focused on music, generate chords, beats, lyrics, melody, and tabs for any song.

U-Net network model for audio source separation, Pitch-Net, Beat-Net, Chord-Net and Segment-Net based on the transformer model. Apart from establishing the correlation between the frequency and time, the most important aspect is to establish the mutual influence between different networks.
The entire AI-powered process is implemented in aitabs.py, while the various network structure models can be referenced in the models folder.
Note:
U-NetandSegment-Netuse the stft spectrum of audio as input.Beat-Netuses three spectrograms of drums, bass, and other instruments as input,Chord-Netuses one spectrogram of the background music.
-
Chord, music chord detection, including major, minor, 7, maj7, min7, 6, m6, sus2, sus4, 5, and inverted chords. Determining the key of a song.
-
Beat, music beat, downbeat detection and tempo (BPM) tracking
-
Pitch, tracking the pitch of the melody in the vocal track.
-
Music Structure, music segment boundaries and labels, include intro, verse, chorus, bridge and etc.
-
Lyrics, music lyrics recognition and automatic lyrics to audio alignment, use ASR (whisper) to recognize the lyrics of the vocal track. The alignment of lyrics and audio is achieved through fine-tuning the wav2vec2 pre-training model. Currently, it supports dozens of languages, including English, Spanish, Portuguese, Russian, Japanese, Korean, Arabic, Chinese, and more.
-
AI Tabs, Generate playable sheet music, including chord charts and six-line staves, using chords, beats, music structure information, lyrics, rhythm, etc. It supports editing functionalities for chords, rhythm, and lyrics.
-
Other, audio source separation, speed adjustment, pitch shifting, etc.

Using a combination of audio STFT, MFCC, and chroma features, with a Transformer model for timbre feature modeling and high-level abstraction, this approach can maximize the avoidance of overfitting and underfitting problems compared to using a single feature, and has better generalization capabilities. With a small amount of data and minimal training, it can achieve better results.

The model begins by processing the audio signal through a U-Net, which isolates the vocal track.
The vocal track is then simultaneously fed into PitchNet and HuBERT (Wav2Vec2). PitchNet is
responsible for extracting pitch features, while HuBERT captures detailed features of the vocals.
The core of the model is CombineNet, which receives features from the Features module. This
module consists of three spectrograms: STFT, MFCC, and Chroma, each extracting different aspects
of the audio. These features are enhanced by the TimbreBlock before being passed to the Encoder.
During this process, noise is introduced via STFT transformation and combined with the features
before entering the Encoder for processing. The processed features are then passed to the Decoder,
where they are combined with the previous features to generate the final audio output.
CombineNet is based on an encoder-decoder architecture and is trained to generate a mask that
is used to extract and replace the timbre, ultimately producing the final output audio.
The entire AI-powered process is implemented in run.py, while the various network structure
models can be referenced in the models folder.
