AllMusicCaps: LeJEPA

LeJEPA objective (negative-free, invariance + SigReg).

Audio-text contrastive (CLAP) model over the OMAR-RQ audio encoder and an all-mpnet-base-v2 text encoder, trained on music with album-review derived captions. Embeddings are 512-dimensional; audio is expected at 24 kHz.

Usage

python

from amclap import get_model

model = get_model(model_id="mtg-upf/allmusiccaps_lejepa", device="cpu")

audio_emb = model.forward_audio(audio)   # (B, 512), audio at 24 kHz
text_emb = model.forward_text(["warm analog synth pads"])  # (B, 512)

Training


Text encoder	frozen (stock all-mpnet-base-v2)
Reported checkpoint	step 149,796
Audio encoder layers	all 12

The text encoder was frozen during training, so stock all-mpnet-base-v2 weights are reloaded at construction.
