mp3

问题 I work on text-to-speech trasforming text, in audio mp3 files, using python 2.5. I use pyTSS as a python Text-To-Speech module, to transform text in audio .wav files (in pyTTS is not possible to encode in mp3 format directly). So after that, I code these wav files, in mp3 format, using lame command line encoder. Now, the problem is that, I would like to insert (in particular point of an audio mp3 file, between two words) a particular external sound file (like a sound warning) or (if possible

问题 I've tried to resolve this by looking at the user guide for jPlayer and via answers to a similar question on Stackoverflow, but unfortunately my ability with javascript is such that I can't implement the suggested answer. I've successfully placed jplayer on my site, styled it and implemented a playlist no sweat. Here's the javascript (snippet - removed extraneous extra songs): $(document).ready(function(){ new jPlayerPlaylist({ jPlayer: "#jquery_jplayer_1", cssSelectorAncestor: "#jp_container

问题 I am using ID3Lib example project to edit Title, Album and Artist ID3 tags on mp3 files and all is good until I come to adding an image (cover Art) if any one has any ideas how to finish off the below code that would be great: - (void)demo { nImage = [UIImage imageNamed:@"amazing-grace.jpg"];//unused NSString *imagePath = [[NSBundle mainBundle] pathForResource:@"amazing-grace" ofType:@"jpg"]; NSString *path = [[NSBundle mainBundle] pathForResource:@"amazing-grace-10s" ofType:@"mp3"]; NSArray

问题 I have been trying to get audio stream of mp3 as array of floating points. I have got the array with the below sample code. I am not sure whether I can use this array for applying FFT. Because this array is not matching[or similar] to the one which I got from C++'s code which uses LAME. import java.io.File; import java.io.IOException; import java.io.PrintStream; import javax.sound.sampled.AudioFormat; import javax.sound.sampled.AudioInputStream; import javax.sound.sampled.AudioSystem; import

问题 I have a problem with getting the metadata of an audio/mpeg (mp3). For example, I'm using JS to get the duration of the audio file and when the cache is empty the duration value returns "Infinity" (NaN). I have tried with the events/attributes preload and onloadedmetadata and always when the cache is empty I can't get the duration and other properties of an audio. Note: The problem is only when I clean the cache (or when the visitors comes first time to the page). audioElement = new Audio(

问题 I am trying to write a Python script to extract metadata tags from some mp3 files. Specifically, I am looking to extract "Album" and "Encoded by", which are available if I right-click on the files and look under details: I am using currently using the eyeD3 library to parse metadata. I am using this library because I thought it would easily accomplish my task, but I am not married to it. I am able to extract the "Album" easily enough, but not the "Encoded by" field. If I print out all the

问题 I am using TagLib (UltraID3Lib couldn't read every MP3 file). Maybe TagLib will do. And I couldn't find properties like Subtitle or Duration or Time? How do I find this kind of tags? Example: "Ondertitel" means Subtitle The second question is: And how can I find the tag Subtitle by using TagLib? 回答1: This way, you can get the duration: var file = TagLib.File.Create(@"xyz.mp3"); Console.WriteLine(file.Properties.Duration); 来源： https://stackoverflow.com/questions/13089205/how-to-read-audio-mp3

问题 I know I can start jPlayer at a given point in time or by percent by doing: $("#jquery_jplayer").jPlayer("playHead", 30); This is when issuing the play command (works fine), but how can I constrain the play time between two fixed points, either by absolute time or percent is fine? Ie I want it to start at 30% and end at 50%, etc. Basically just a good snippet of a song. Any ideas or pointers? http://www.happyworm.com/jquery/jplayer/latest/developer-guide.htm#jPlayer-playHead 回答1: Well in

问题 test1.mp3 and test2.mp3 have the same bitrate and sample rate, and I'm trying to merge them in an HTTP response. The resulting file is test.mp3. test.mp3 plays fine in WMP12 and VLC. In WMP11, I hear only the audio which came from test1.mp3. At the moment you expect to hear the beginning of test2.mp3's audio, the player stops playing. WMP11 reports no errors... it just stops playing. What needs to change such that test.mp3 will play correctly in WMP11? protected void Page_Load(object sender,

问题 I'm working on a Radio Streming application for Android. The music is well recieved and played by the MediaPlayer class, but the problem is when I try to retrieve the Metadata, the App blocks and returns errors.
