问题 I need to bring the mp3 file information like Artist, Album, Who sung the song, Title etc on Jplayer .How can i bring this. Please give me link if there is any tutorial on this. 回答1: This is not possible with Javascript, you will need a server side language or client side plugin to determine the ID3 information of your MP3 file. However, another option is to store these along in a database when you upload your music which removes the need for reading the ID3 tags... 回答2: This might help. (It

问题 How do I play an audio file(.mp3) in C# with very little delay? What I mean is, the file should start playing the right after user input is provided and later than that. Also, how can I play two audio files in parallel at the same time? 回答1: Take a look at the NAudio library. For playing multiple files at the same time, see this post. 回答2: To get minimally possible delay you need audio playback running with with no/silence data and on the event of interest you will supply real playback data

问题 I was in the process of making a program that simply repeats any text you enter, and seemed to be working when I first tested it. The problem is that the second time I attempt to type anything, it crashes and says that permission was denied to the sound file I was recording it to. I believe it is because the file was already opened, but none the less I do not know how to fix it. I am using the gTTS and Pygame modules. from gtts import gTTS from tempfile import TemporaryFile from pygame import

问题 Read MP3 Tags with Silverlight got me started with reading id3 tags, but i realize that taglib# online deals with local file paths ? Is there a way of reading this info from a remote file ? 回答1: I recently answered the same question for Ruby (see below) - I'm pretty sure you can do something similar. The idea is: use HTTP 1.1 protocol or higher, and a Range HTTP-request. download the beginning section (100 bytes) of the ID3v2-tag from the first few bytes downloaded, you can determine the

问题 Has anybody experienced this? I use notification.sound to set a custom sound and a phone still uses the default sound. I copied a sound from audio-resources.zip/audio/alarms/Instance.mp3 . (You can download audio-resources.zip here). I copied it and moved/renamed it to res/raw/notification.mp3 . I am using this code to make the sound. //Old way: notification.defaults |= Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE; notification.defaults |= Notification.DEFAULT_VIBRATE;

问题 I currently have a simple flash Mp3 player on my site which works lovely. The issue is, most cell phones do not support flash and a large portion of my visitors come through via a mobile device. The alternative to this is to replace the flash player with a javascript player. I found a JQuery one but it only works on HTML5 compatible browsers. Does anyone know of a good alternative that would work on mobile devices as well as most desktop web browsers? 回答1: You can check if the browser

问题 I want to mix 2 audio files together - one file has a length of 2 mins and the other is a 10 second sound. I want both files to mix so both sounds can still be heard. I want this 10 second clip to come in exactly at 30 seconds for the 10 seconds so it will end at 40 seconds. I know how to mix 2 audio files together using ffmpeg ffmpeg -i input.mp3 -i input2.mp3 -filter_complex amerge -c:a libmp3lame -q:a 4 output.mp3 However, I do not know how to start this 10 second sound at a specific time.

问题 I'm trying to write a mp3 player using mci functions.(win 7 64bit,vs2010,c++) when i try to play a mp3 file with the flag "wait" i can hear the file but everything else is stuck until the file ends playing, if i remove the flag "wait" i can continue working but can't hear a thing. here is a sample of the code: unsigned long __stdcall PlayThread(void *myParam) { char* nameOfMp3 = (char*)myParam; char* cmd = new char[MAX_PATH]; sprintf(cmd,"open \"%s\" type MPEGvideo alias myFile",nameOfMp3);

问题 How can I parse an MP3 file to get its all attributes? Also how to edit and the attributes of the MP3 file? Is there any class available in .NET v4.0? 回答1: Those attributes are called ID3 tags. I do not think it is the scope of the .NET framework to provide reading them. Here is some code from SourceForge. http://sourceforge.net/projects/csid3lib/ 回答2: You might have a look at the taglib library for .NET. It can do both reading and writing of id3 tags among other things. 来源： https:/

问题 I need to convert a continuous stream of PCM, or encoded audio (ADPCM, uLaw, Opus), into MP3/OGG format so that it can be streamed to a browser (using html's audio tag). I have the "stream-mp3/ogg-using-audio-tag" part working, now I need to develop the conversion layer. I have two questions: How can I convert PCM into MP3/OGG using NAudio and/or some other C# library/framework? I assume there is a code snippet or two in the NAudio demo app that may be doing this, but I haven't been able to
