audio

问题 I'm trying to play an audio file. In my IDE (intellij) that works completely fine, but when running in a JAR, I get the error java.io.FileNotFoundException: D:\soni801\Documents\Redsea Productions\The Great X Wars\alpha-0.0.7.1.jar\audio\click.au (The system cannot find the path specified) The file's location inside the JAR is audio/click.au , and the JAR is located at D:\soni801\Documents\Redsea Productions\The Great X Wars\alpha-0.0.7.1.jar which afaik should make the absolute path D:

问题 i will record the sound from my programs. I use Ubuntu 14.04 and PulseAudio. Now i try to record from pulseaudio but currently i'm only recording from my microphone. How can i record the sound from pulseaudio instead of my microphone? public static void captureAudio() { try { final AudioFormat format = getFormat(); DataLine.Info info = new DataLine.Info(TargetDataLine.class, format); final TargetDataLine line = (TargetDataLine) AudioSystem.getLine(info); line.open(format); line.start();

问题 I have a script at present that results in several audio-only and video-only files. My goal is to take these and then concat each video clip whilst merging in the audio-clips. I thought this would be easy but I have not been able to find a good example to work from. FFMPEG.org suggests that the movie/amovie input syntax could be the best option.. but am craving more doco. FFMPEG's information on the topic is @ https://www.ffmpeg.org/ffmpeg-filters.html#Examples-124. It suggests that to "..

问题 I would like to use the Phone Speakers while a Headset is plugged-in, instead of the Headset-Speakers. Is it possible to do that? if yes, how can I achieve it? I'm developing an App in Java for Android 9 .

问题 I have a short (~1 second) arbitrary sound file and two devices. At some unknown time, device 1 will play the sound file out of its speaker. Device 2 should then be able to detect that sound. There may be background noise. It's unknown how loud the sound will be played. This feels like it should be a common solved problem, but searching for answers has left me with nothing. If anyone has good a solution or could just point me in the right direction I'd be very grateful. 回答1: In most distance

问题 I am creating a voip app for iOS in objective-c. Currently i am trying to create the audio part: recording the audio data from microphone, encoding with Opus, decoding, and then playing.

问题 I'm new to soundio. I'm wondering how to play more than one audio source at once. I'm looking to understand if I'm supposed to create several streams (seems wrong) and let the operating system do the mixing, or am I supposed to implement software mixing? Software mixing seems tough too if my input sources are operating at different frequencies. Am I basically asking "how to mix audio"? I need a little direction. Here's my use-case: I have 5 different MP3 files. One is background music and the
