mp3

问题 When I try to play .mp3 file by using AudioClip with JavaFX 8u40 it says: com.sun.media.jfxmedia.MediaException: Could not create player! which means Java installation do not see my mp3 codec - but all other OS programs see it, even programs on Qt can play mp3. This error happened after upgrading to Ubuntu 14.10 (On 14.04 all was fine, the same programs play all the media formats) libav... all packages are all installed. 来源： https://stackoverflow.com/questions/27195853/javafx-mp3-playback

问题 I'm getting a base64 string from android side. I have to convert it into an audio file and have to save it into a folder. I thought I have to convert it first into byte array. Then after it, I have to convert it into a mp3 file. But don't know how. I have done work in base64 to image. If anyone know answer then please explain with an example. Thank You. 回答1: If the base64 encoded data already represents an MP3 file, it should be as easy as decoding the base64 data and storing it in a file:

问题 I'm looking for the ID3v2 documentation/norm. The official site id3.org seems to be unreachable. Is this specification still used ? (I'm wondering this because of the "downness" of the official website) 回答1: The availability of any website is unbound to the use of any specification, because even if one or both of it become outdated all files that used it until that date won't disappear magically at that date - software still needs to expect old files that have been crafted when "old"

问题 I am trying to play mp3 file in java program using javafx. I installed dependencies libavcodec53 and libavformat53 mentioned here. I used following code public void play(String path_to_song){ JFXPanel fxPanel = new JFXPanel(); String song = new File(path_to_song).toURI().toString(); Media audio =null; audio = new Media(song); MediaPlayer mediaPlayer = new MediaPlayer(audio); mediaPlayer.play(); } But I still got error "Error media audio format unsupported" Exception in thread "main"

问题 I want to be able to read ID3v2 tags from mp3 files. I have found multiple frameworks which allow me to get the basic tags. But I would like to be able those in this list. I don't care about backwards compatibility with IDv1. I already had a look at Jaudiotagger and mp3agic. I didn't find out how to use them for custom tags. Is this possible? 回答1: You've to use the string identifier "TXXX", that's the main difference between "normal" and custom fields. I think the following code should be

问题 This is something I have been trying to do for a while, and is more of an open ended question. If anyone has any knowledge that can help me shed some light on this, it would be very much appreciated. I want to decode the audio stream in an mp3 and use that to drive animation, all using python. As I understand it, the audio data in an mp3 is stored in frames of 32 frequency subbands (or frequency bins), which is ideal for me - if I could take an mp3 and extract an amplitude for each subband on

问题 I have an application written using c# on the top of Asp.Net MVC 5 framework. My objective is to make a call to 3rd party service to download a wave file. Then I want to convert this file into mp3. Finally, I want to return the mp3 file as (byte[]) to allow the user to download it directly from memory. Here is how my code will end up which allow the user to download the converted file from the memory public ActionResult Download(int? id) { // Download and convert the file // the variable
