This article presents a detailed design and implementation plan for adding configurable noise‑reduction to both traffic recording and result comparison in Alibaba's jvm‑sandbox‑repeater, including new configuration fields, comparator extensions, and a Quartz‑based denoising job with Akka integration.
The article details the development of '质臻影音' technology by Kuaishou's audio-visual team, which uses AI algorithms to restore classic films and enhance video quality through techniques like super-resolution, noise reduction, and adaptive processing strategies.
This article presents a deep‑learning approach that transforms recorded audio into spectrograms, trains a noise‑prediction network (e.g., ResNet, U‑Net, LSTM) to estimate environmental noise, subtracts it in the frequency domain, and reconstructs a cleaner signal for more accurate audio‑device quality assessment.
This article examines the challenges of live‑stream audio noise, compares open‑source denoising solutions such as Speex, WebRTC, and RNNoise, and details the practical integration, performance testing, and final adoption of WebRTC‑based noise reduction within the 58 live‑stream Android SDK.
Tencent Cloud Gaming Multimedia Engine (GME) tackles the intense, non‑stationary background noise of internet cafés by employing a specialized voice‑activity detection algorithm combined with mean removal, low‑pass and numerical filtering, enabling it to isolate a primary speaker’s voice and suppress surrounding chatter, clicks, and music for clear in‑game communication.
