Real-Time Noise Suppression Using Deep Learning | NVIDIA Developer Blog
Imagine waiting for your flight at the airport. Suddenly, an important business call with a high profile customer lights up your phone. Tons of background noise clutters up the soundscape around you — background chatter, airplanes taking off, maybe a flight announcement. You have to take the call and you want to sound clear. We all have been in this awkward, non-ideal situation. It’s just part of
RNNoise: Learning Noise Suppression
The image above shows the spectrogram of the audio before and after (when moving the mouse over) noise suppression. Here's RNNoise This demo presents the RNNoise project, showing how deep learning can be applied to noise suppression. The main idea is to combine classic signal processing with deep learning to create a real-time noise suppression algorithm that's small and fast. No expensive GPUs re
How To Do Noise Reduction Using ffmpeg And sox
Need a quick, easy and free way of cleaning up a video’s audio from background noise ? Follow the steps below to remove background audio from videos. First get and install the tools: FFMPEG. SoX – Sound eXchange. Then clean your noise! Split the audio and video streams into 2 seperate files: The VIDEO stream: ffmpeg -i input.mp4 -vcodec copy -an tmpvid.mp4 The AUDIO stream: ffmpeg -i input.mp4 -ac
mp3などの音源をxhrしてきて再生するには - console.lealog();
過去に何回も書いてるはずやのに、どういうわけか毎度ハマる。 今度こそメモっておく。 音源を取得する const xhr = new XMLHttpRequest(); xhr.open('GET', '/path/to/audio', true); xhr.responseType = 'arraybuffer'; xhr.onload = () => { // ここで処理 // xhr.response; }; xhr.send(); バイナリを取得するのでそれ用の`responseType`が重要。 `blob`か`arraybuffer`かどっちかになるはずで、あとの処理でどういうことするかによる。 2017年やけど、jQueryの`ajax()`は、このへんの設定が上手くできないっぽいので注意。 ここで取得できない場合は、音源が見つけられてない。 パスにスペースがある時はちゃんとエ
Subvisual | Tutorial: HTML Audio Capture streaming to Node.js (no browser extensions)
Tutorial: HTML Audio Capture streaming to Node.js (no browser extensions) I'm taking the time to write the tutorial I wish I had some months ago. My task was to set up some user voice recording mechanism in the browser. It should record for about one hour, non-stop, saving to a server. The idea was to use the getUserMedia() API. No browser extensions should be used. The getUserMedia() API allows w
Media Capture and Streams と Web Audio API で実現する録画・録音・ WAVファイルの生成 | CYOKODOG
前回のエントリではマイク経由の音声認識を行う Speech Recognition API を試しましたが、今回はカメラ・マイクからの動画・音声キャプチャを行う Media Capture and Streams を試してみます。 また、キャプチャした音声の録音については MediaStream Recording を使用することで可能ですが、現時点（2015年4月）では Firefox にしか実装されていません。 そこで Web Audio API を使用することで他のブラウザでも音声録音を可能にし、それらの音声データを wav 形式で保存する方法についても試してみました。 はじめに ベンダープレフィックス対策として以下処理を行います。 code demo script navigator.getUserMedia = navigator.getUserMedia || navigato

Free Online Guitar Tuner by Tom Hoddes
Welcome to the future of online tuners Unlike most other online tuners, this is built on new WebRTC technology. What does that mean for you? Previously tuner's have required the use of flash, which is becoming an outdated technology and requires plugins for your browser. Need a guitar tuner for iOS? WebRTC is not yet supported on any of the iOS browsers. Until that time I recommend any of the free

Audio Sprites (and fixes for iOS)
I recently had to work on a project for iOS that required that sound play on particular actions being performed. The problem is that iOS and HTML5 has been seriously oversold by Apple and the devices are pretty poor in comparison to the desktop. Audio and video are particularly poor, so to solve my problem I used an audio sprite, a technique that was similar to CSS sprites, just for audio. READER
Audio5js - The HTML Audio Compatibility Layer
Audio5js is a Javascript library that provides a seamless compatibility layer to the HTML5 Audio playback API, with multiple codec support and a Flash-based MP3 playback fallback for older or unsupported browsers. The motivation for creating Audio5js is to provide a light-weight, library-agnostic, Javascript-only interface for audio playback in the browser.
