mp3

问题 I'm trying to write my own media player (like Foobar), and I'm having trouble tracking down a Python library that'll play MP3s. I know Pymedia does mp3s, but it looks outdated - the latest installer is for Python version 2.4, and I'm using 2.6. I've never had much success with Pygame, and Pyglet doesn't look like it has too much in the way of documentation. Are there any other alternatives? 回答1: There is http://pyglet.org/ and also have you tried http://code.google.com/p/mp3play/? It's also

问题 I've looked at pymedia (discontinued), pyglet(great but no converter in there) and audiotools(command line cd ripping), and none seem suitable. In Python 2.7 , how do you do convert(wavFileLocation, 'mp3') If there is no python way, how would you do it in a manner which python can invoke? (e.g. Call a Cross platform command line tool... if exists return (name, pythonCodeForInvocation) ) 回答1: using lame (command line), you can encode wav to mp3 like this: $ lame --preset insane /path/to/file

问题 FFMPEG is really a great tool. I know it can edit ID3 tags and even remove all tags in a row : ffmpeg -i tagged.mp3 -map_metadata -1 untagged.mp3 But even after that, there's still the cover image. I don't know how to remove it using ffmpeg. I know there's other soft out there that can do the job - like eyed3 - but what's the point to install it if ffmpeg can do it too, in one line, while encoding the audio ? 回答1: The cover image/album art is treated as a video stream by ffmpeg. To omit it

问题 The answers provided in How do I get a sound file’s total time in Java? work well for wav files, but not for mp3 files. They are (given a file): AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(file); AudioFormat format = audioInputStream.getFormat(); long frames = audioInputStream.getFrameLength(); double durationInSeconds = (frames+0.0) / format.getFrameRate(); and: AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(file); AudioFormat format =

Basically, I have a lot of audio files representing the same song. However, some of them are worse quality than the original, and some are edited to where they do not match the original song anymore.
