Language-queried audio source separation (LASS) aims to separate sound sources based on textual descriptions of the desired source.
Current state-of-the-art (SoTA) models primarily use discriminative approaches, such as time-frequency masking, to separate the target sounds while reducing interference from other sources.
However, these models may encounter challenges in separating overlapping soundtracks, degrading the overall performance in real-world scenarios.
Recently, the subjective quality of separated sound was enhanced successfully via generative approaches, such as diffusion-based models.
Rectified flow matching(RFM), a variant of the diffusion-based generative model that establishes linear connections between the distribution of data and noise, offers superior theoretical properties and simplicity,
but has not yet been explored in sound separation. In this work, we introduce FlowSep, a novel generative model based on RFM for LASS tasks.
Specifically, FlowSep learns linear flow trajectories from Gaussian noise to the target source features within a pre-trained latent space. During inference,
the mel-spectrogram can be reconstructed from the generated latent vector with the pre-trained variational autoencoder (VAE) decoder.
Trained on 1,680 hours of audio data, FlowSep outperforms SoTA models across multiple benchmarks, as evaluated on subjective and objective metrics.
Additionally, our results show that RFM surpasses diffusion-based approaches in both separation quality and inference efficiency, highlighting its strong potential for audio source separation tasks.

FlowSep is an RFM-based generative model for text-based audio source separation. FlowSep comprises four main components: a T5 encoder for text embedding, a rectified flow matching
(RFM) generator for creating audio features within the latent space, a VAE decoder for reconstructing the mel-spectrogram, and a GAN vocoder to produce the final waveform.
