From Cheap to Chic: Enhancing Music Playback Quality of Budget Earphones via Hardware-Aware Learning
Low-end earphones are widely spread due to their affordability, but their limited speaker hardware often leads to poor music playback quality. This raises a key question: Can we compensate for hardware limitations to enhance the listening experience without modifying the device? Existing EQ-based approaches attempt this, but they rely on frequency response curves (FRCs) measured under ideal conditions, which fail to capture real-world distortions such as harmonic and intermodulation effects. To address this, we propose Cheap2Chic, a two-stage, speaker-aware framework that improves music playback quality on low-end earphones using deep learning. In stage one, Cheap2Chic trains a speaker characterization model to capture the playback properties of the target earphone. In stage two, it introduces a digital audio enhancement model, prepended before the frozen speaker characterization model, that learns to adapt the input audio to compensate for hardware-induced distortions. To reduce the data collection burden re…

Chart-to-code generation converts a chart image into an executable plotting script, enabling faithful reproduction and editable visualizations. Existing methods are largely Python-centric, limiting practical use and overlooking a critical source of supervision: the same chart can be expressed by semantically equivalent scripts in different plotting languages. To fill this gap, we introduce Chart2NCode, a dataset of 176K charts paired with aligned scripts in Python, R, and LaTeX that render visually equivalent outputs, constructed via a metadata-to-template pipeline with rendering verification and human quality checks. Building on a LLaVA-style architecture, we further propose CharLuMA, a parameter-efficient adaptation module that augments the multimodal projector with a language-conditioned mixture of low-rank subspaces, allowing the model to share core chart understanding while specializing code generation to the target language through lightweight routing. Extensive experiments show consistent gains in exec…
