Researchers have developed AudioTQ, a novel 6-bit audio codec that operates directly in the time domain, bypassing traditional psychoacoustic modeling. Inspired by techniques used in large language model weight quantization, AudioTQ employs a randomized Fast Walsh-Hadamard Transform for amplitude uniformization, followed by a Lloyd-Max quantizer and a residual correction layer. This approach allows for real-time, single-threaded execution on standard CPUs and achieves a signal-to-quantization-noise ratio of approximately 30 dB, with benchmarks indicating up to a 74.4% reduction in file size.
