Neural Audio Codec を用いた大規模配信文字起こしシステムの構築 - Mirrativ Tech Blog
こんにちは ハタ です。 最近Mirrativ上に構築した配信の文字起こしシステムを紹介したいなと思います 音声からの文字起こしは、各社SaaSでAPI提供されているものがあると思いますが、今回紹介するものはセルフホスト型(自前のGPUマシンを使う)になります 構築していく上で色々試行錯誤したのでそれが紹介できればなと思っています どんなものを作ったか 前提知識: 配信基盤 前提知識: Unix Domain Socket Live Recorder Archiver DS Filter VAD Filter NAC / Compress Transcriber NAC / Decompress Speach To Text コンテナイメージ まとめ We are hiring! どんなものを作ったか 今回作ったものは Mirrativで配信されるすべての音声を対象に文字起こしを行う シス

Lyra V2 - a better, faster, and more versatile speech codec
The latest news from Google on open source releases, major projects, events, and student outreach programs. Since we open sourced the first version of Lyra on GitHub last year, we are delighted to see a vibrant community growing around it, with thousands of stars, hundreds of forks, and many comments and pull requests. There are people who fixed and formatted our code, built continuous integration
GitHub - google/lyra: A Very Low-Bitrate Codec for Speech Compression
The basic architecture of the Lyra codec is quite simple. Features are extracted from speech every 20ms and are then compressed for transmission at a desired bitrate between 3.2kbps and 9.2kbps. On the other end, a generative model uses those features to recreate the speech signal. Lyra harnesses the power of new natural-sounding generative models to maintain the low bitrate of parametric codecs w
It’s High Time to Replace JPEG With a Next-Generation Image Codec
I can be quite passionate about image codecs. A “codec battle” is brewing, and I’m not the only one to have opinions about that. Obviously, as the chair of the JPEG XL ad hoc group in the JPEG Committee, I’m firmly in the camp of the codec I’ve been working on for years. Here in this post, however, I’ll strive to be fair and neutral. The objective is clear: dethroning JPEG, the wise old Grandmaste
Hello, Video Codec!
It can't be overstated how crucial video codecs are to the products we use every day. Without them, we wouldn't be able to watch videos on YouTube or meet remotely via Zoom. But how do they work? In this post, we'll explore at a high level the key concepts and defining characteristics of video codecs. Then, to further demystify them, we'll even implement one from scratch in about a hundred lines o

How to Check Which Bluetooth A2DP Audio Codec Is Used on Windows • Helge Klein
by: Helge, published: Sep 9, 2020, updated: Sep 16, 2020, in Windows General This is a follow-up to my earlier article Bluetooth Audio Quality & aptX on Windows 10, based on a comment by reader eluxe. Windows makes it unnecessarily hard to identify the audio codec used by the Bluetooth A2DP profile, but there is a way. This post shows how to check if your connection makes use of aptX, LDAC, or som
Why Rust is not a mature programming language « Kostya's Boring Codec World
While I have nothing against Rust as such and keep writing my pet project in Rust, there are still some deficiencies I find preventing Rust from being a proper programming language. Here I’d like to present them and explain why I deem them as such even if not all of them have any impact on me. Rust language problems First and foremost, Rust does not have a formal language specification and by that
At Meta, we support real-time communication (RTC) for billions of people through our apps, including WhatsApp, Instagram, and Messenger. We are working to make RTC accessible by providing a high-quality experience for everyone – even those who might not have the fastest connections or the latest phones. As more and more people have relied on our products to make calls over the years, we’ve been wo
Web video codec guide - Web media technologies | MDN
This guide introduces the video codecs you're most likely to encounter or consider using on the web, summaries of their capabilities and any compatibility and utility concerns, and advice to help you choose the right codec for your project's video. Due to the sheer size of uncompressed video data, it's necessary to compress it significantly in order to store it, let alone transmit it over a networ
