由 喜你入骨 提交于 2019-12-08 01:34:16
问题 What options do I have for converting MP3's to OGG on the fly using PHP? I assume the only way to do this is via the command line with an execute statement. Is this true? If so, what converters (and associated commands) would I be best off using? I have tried: oggenc2.exe but was told by the program that the MP3 I passed was not a valid filetype ffmpeg.exe but was unable to figure out how to go from mp3 to ogg (found how to go from ogg to mp3 though) Convert mp3 to ogg via php 回答1: You didn't

问题 I am very stuck in knowing what to do to integrate my JFXPanel (which is an mp3 player) into an existing Swing app that - which is a JFrame with several different JPanels added to it.

Is it possible to read music file metadata using R?

由 半腔热情 提交于 2019-12-07 22:53:30
问题 I've got a bunch of audio files (let's say ogg or mp3), with metadata. I wish to read their metadata into R so to create a data.frame with: file name file location file artist file album etc Any way you know of for doing that ? 回答1: You take an existing mp3 or ogg client, look at what library it uses and then write a binding for said library to R, using the existing client as guide for that side -- and something like Rcpp as a guide on the other side to show you how to connect C/C++ libraries

Java library for extracting audio information from MP3 files

由 馋奶兔 提交于 2019-12-07 21:46:45
问题 Is there any freely available library (other than java media framework) that I can use to extract the bit rate (eg. 128 kbps, VBR) and the audio quality (eg 44.1KHz, Stereo) from a MP3 file? I would like a standalone library that I can incorporate into my application jar, to be deployed on older Macs too that have only Java 1.5 available and I can't get them upgraded or add any big Java library to. Just to clarify: I will not play, transcode or do anything of the sort with the audio stream

Phonegap Media record mp3 file corrupt

由 折月煮酒 提交于 2019-12-07 19:14:25
I am using phonegap media to record audio as mp3. After recording, it plays fine on my Android and plays fine on Windows Media Player.

由 微笑、不失礼 提交于 2019-12-07 18:41:33
问题 Is it possible to convert an audio mp3 file to a string file, or read the mp3 file and write in a text file and vice versa? If possible then how?

If you're asking if you can convert an audio file to a string then that is an incorrect question as binary data is only

由 怎甘沉沦 提交于 2019-12-07 17:33:40
问题 I have a byte array containing an MP3 stream. Is it correct to assume that this stream would have to be further decoded if I want to be able convert to a WAV?

问题 I have MP3s and other file formats that I want to provide through my website to iPhone and iPad users.
