问题 I am trying to get the BPM property from an MP3 file: I can see how to do this in a Windows Store App as per this question: How to read Beats-per-minute tag of mp3 file in windows store apps C#? but can't see how to use Windows.Storage in a Windows Forms app. (If I understand it correctly it's because Windows.Storage is specific to UWP.) How can I read this in a Forms app? Happy to use a (hopefully free) library if there is nothing native. 回答1: You can use Windows' Scriptable Shell Objects

由 元气小坏坏 提交于 2019-12-22 04:15:10
问题 There's something very weird on my server- chrome won't play mp3 files on it. for example, when chrome is pointed to an mp3 file on first server: http://tinyurl.com/czqfw5a - it won't play. When I place the same file on my second server: http://tinyurl.com/cju4yg4 - it works fine. I checked http response headers, on both servers it looks fine- mime type is set correctly. The problem happens only with chrome. ff / ie work fine. Anyone have an idea? 回答1: Short story , it's this bug: http://code

由 冷暖自知 提交于 2019-12-22 01:02:04
问题 What is the best way to trim a mp3 file programmatically. For example, say I want to get rid of the first 2 minutes or last 2 minutes or both. Is there a good way to do this from .NET? Or .NET calling out to a command line tool? 回答1: There are two approaches to trimming MP3 files: First, convert to WAV, trim off the samples you don't want, and then convert back to MP3. The disadvantage is that there will be a very slight loss of quality in the process. The advantage is that you will find

Get metadata of local mp3 file using html5 filesystem api

由 我的梦境 提交于 2019-12-21 20:52:32
问题 I was trying to get the title and artist (and other metadata eventually) of each mp3 file in a directory. Currently the code I have appends the div "thelist" with the file name of the mp3 file. How could I go about getting the title and artist properties/tags of the file instead of the entire file name? Here is my code: <!DOCTYPE html> <html> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Get Directory</title> <script type="text/javascript" src="jquery.min

由 纵饮孤独 提交于 2019-12-21 20:35:14
问题 I can successfully get the mp3 ID3 tags out of my mp3 app, using php. I am left with a huge BLOB. I'm sure this is pretty straightforward, but I just need a little help in the right direction.

The first two lines work fine

Is it possible, using TagLibSharp, to remove a Lyrics3v2 tag from a MP3 file?

由 本秂侑毒 提交于 2019-12-21 20:29:22
问题 I wonder if it's possible to remove a Lyrics3v2 tag type from a MP3 file using TagLibSharp library. This documentation says that the block entry starts with word " LYRICSBEGIN " and ends with " LYRICS200 ", also it says that the ID3 tag should be present to let exists the Lyrics3v2 tag ...but it doesn't specifies if reffers to ID3v1 or ID3v2 tag, or any of them, anyways I don't understand that part, because Lyrics3v2 tag is a single tag type, is not part of an ID3v1/ID3v2 tag type, it has its
