问题 I need to implement a voice activity detection algorithm in Java so that I can know when to start and/or stop recording audio. I am looking for an algorithm that can take either a byte[], a target-data-line, or an audio file as input. Also, a solution would preferably not use external dependencies. 回答1: Give a look at TarsosDSP as source of inspiration: It is so far the best open source Java library to deal with Audio Detection. It is purely written in Java and briefly provides:

问题 Android 9 limits the ability for background apps to access user input. If your app is running in the background on a device running Android 9, the system applies the following restrictions to your app: Your app cannot access the microphone or camera. Is there any way to access microphone in android 9 while the app is in the background. 回答1: One more change was added in Android 9: only apps running in the foreground (or a foreground service) could capture the audio input.

问题 I understand there are various flags/parameters you can pass using desired caps to enable access to camera, microphone, etc. For instance on Chrome you can use ChromeOption and pass ' profile.default_content_setting_values.media_stream_mi ' under ' prefs '. I wish to enable the microphone access on Edge browser. I am not able to find any related information. Can somebody assist me here? For Chrome you can enable the same like mentioned here- How to allow or deny notification geo-location

问题 I want to make a soundboard program for my friends and myself with a few meme sounds we find funny. I already have a working base with one button, that plays the desired sound. Now I just need to figure out a way how to make the audio play through my microphone (simulate microphone input). I already searched the internet and didn't find the exact solution I was looking for. Here is the code I already have: import tkinter as tk import pygame root = tk.Tk() root.title("Soundboard"); root

问题 I'm trying to implement speech recognition into the electron application. The solution works in chrome browser, but does not work in electron. The application stops listening immediately - it probably has no microphone permission. How to grant permissions? index.js const electron = require('electron'); const url = require('url'); const path = require('path'); const { app, BrowserWindow, ipcMain } = electron; let mainWindow; ipcMain.on('close-me', (evt, arg) => { app.quit() }) app.on('ready',

问题 Is there a way using python (and not any external software) to play a mp3 file like a microphone input? For example, I have a mp3 file and with a python script it would play it through my mic so other in a voice room would hear it. As I say it is just an example. Of course, I have done some research. I found out that I can use a software to create a virtual device and do few things to have the result. But my point is if it is possible without installing software but with some kind of python

问题 I'm part of a team developing applications for flight simulation. One of these applications is running also on MacOS and needs access to the microphone to communicate with online virtual air traffic control. Starting with MacOS 10.14 microphone access is no longer working. It used to work perfectly in any previous version of MacOS. I've read that starting with 10.14, MacOS will ask the user for permission, but this dialog never appears. Using portaudio as the audio library, audio input stream

Please give me a suggestion to solve this problem to increasing microphone Volume level in Android or
