TAPE: Learning General Audio Effect Representations

TAPE (Transformations of Audio Parameter Embeddings) is a system that learns to infer the signal‑processing chain applied to a reference audio recording and then applies the same chain to new material. It uses an encoder to map the processed reference to an embedding that a differentiable DSP decoder translates into editable parameters for equalization, compression, waveshaping, a residual network, and reverberation. Compared to prior methods, TAPE achieves lower spectral error while being 275× faster than exhaustive search and can run causally in real time on 128‑sample buffers.

How Much Audio Is Left In An Embedding? An Inversion Audit Of Audio Encoders

The paper investigates how much original audio information remains in frozen representations from various pretrained audio encoders by attempting to reconstruct five‑second, 44.1‑kHz stereo music clips. Using a shared Stable Audio Open latent diffusion decoder, the authors reconstruct audio from embeddings produced by supervised classifiers (VGGish, ConvNeXt), an audio‑text contrastive model (CLAP), and a waveform‑reconstruction model (EnCodec). Results on the Million Song Dataset reveal that reconstructability varies across encoder families and that embeddings exposing finer temporal or spectral detail enable better recovery of source content, even for compressed, task‑oriented embeddings.

CPR: Combining global composing, local performing and full-sequence refining in piano rendering with continuous autoregressive modelling

The paper introduces CPR, a piano rendering framework that combines continuous autoregressive modeling with local flow matching and full‑sequence refinement. It predicts continuous hidden states, generates 24 kHz acoustic latents, and upsamples to 48 kHz, while new techniques BREPA and MT‑RoPE enhance musical semantics and cross‑modal alignment.

Adding Voice Cloning to Text-to-Audio-Video Models with a Single Zero-Initialised Layer

arXiv:2608. 15690v1 Announce Type: cross Abstract: Text-to-audio-video (T2AV) generation models produce a video and its soundtrack from a textual description, but offer no control over whose voice speaks in the output.

SAGE: Semantic Audio Generative Encoder

SAGE, a 105‑million‑parameter semantic audio generative encoder, compresses music waveforms into compact latent representations by distilling embeddings from a pretrained audio‑text model. It achieves a three‑way balance—high reconstruction quality, rich semantic latent structure, and fast inference—running three times faster than Stable Audio Open while matching or surpassing larger models in listening‑test quality and objective metrics. Across all nineteen latent‑semantics probing tasks, SAGE sets new state‑of‑the‑art performance both within and outside its training domain.

Spot, Separate, and Enhance: Fully Generative Approach for Audio Mixing

Spot, Separate, and Enhance (SSE) is a multimodal, user‑guided generative model for audio remixing and enhancement. It rebalances audio, removes unwanted sources, and reduces reverberation using video and textual guidance. The authors introduce the DegradedMix dataset and adopt generative evaluation metrics, showing SSE outperforms existing baselines in controllability and remixing quality.

X-AVDD: Cross-Attentive Audio-Visual Dataset Distillation

X-AVDD is a cross‑attention‑based audio‑visual dataset distillation method that explicitly models inter‑modal relationships during synthesis. By decoupling cross‑modal alignment from joint optimization, it reduces memory usage and end‑to‑end GPU‑hour cost by about eight times while producing highly aligned synthetic data. Empirical results show significant performance gains over prior methods, improving top‑1 test accuracy on VGGSound from 8.2 % to 24.0 % at 10 samples‑per‑class and enabling efficient scaling to complex architectures such as AudioCLIP.
