mp3

问题 I'm trying to send my mp3 files through a PHP script in order to hide the path to the file in the HTML. Everything works perfectly fine except half way into the mp3 chrome gives me a GET [URL] error. And the rest of the mp3 is just blank. The audio tag thinks it's still reading the file, but there is no sound. This is how I'm sending the mp3 file from php: if (file_exists($filename)) { header("Content-Transfer-Encoding: binary"); header("Content-Type: audio/mpeg"); header('Content-length: ' .

问题 I am using id3.net tagging library for reading and modifying tags,although with the help of this api i can read all id3 tags but i am facing problem in modifying tags.http://id3.codeplex.com/ Id3.Mp3File fs = new Id3.Mp3File(@"test.mp3",Id3.Mp3Permissions.ReadWrite); Id3.Id3Tag[] tags= fs.GetAllTags(); tags[0].Album.Value = "test"; fs.WriteTag(tags[0],Id3.WriteConflictAction.Replace); fs.Dispose(); please guide me if i am doing something wrong .if use this overload fs.WriteTag(tags[0],Id3

问题 I've searched related questions but wasn't able to find any relevant info. I'm trying to get the Web Audio API to play an mp3 file which is encoded in another file container, so what I'm doing so far is parsing said container, and feeding the result binary data (arraybuffer) to the audioContext.decodeAudioData method, which supposedly accepts any kind of arraybuffer containing audio data. However, it always throws the error callback. I only have a faint grasp of what I'm doing so probably the

问题 I am in an ASP.NET project using C#. The users can upload their MP3 (I have no control over the encoding) and specify a sample size and a sample starting point. On save, the system needs to create a sample of this MP3 based on the information provided. So the question is: How can Icrop a mp3 in ASP.NET + C#?? 回答1: While you could possibly use a .NET audio library to do this, I think the easiest way to do this would be to run a command like FFMpeg or MPlayer to do the cropping for you, then

问题 I have a heap of audio files on a CDN. Those are mp3's and ogg vorbises, in parallel. Those files are each worth about one hour of playback. I need to extract arbitrary parts from those files: I am given a filename (I can choose if I use the mp3 or ogg version) and two timestamps and I need the audio exactly between the given time positions. I don't want to download the whole file, so I think of using the Range http header. I have complete control over the audio files, so I encoded them in

问题 I am new in ios developement.I am encoding a LinearPCM to MP3 in iOS.I'm trying to encode the raw PCM data from microphone to MP3 using AudioToolbox framework and Lame.And although everything seems to run fine if i record .caf format . i am getting only noise and distortions present in the encoded stream. I'm not sure that I setup AudioQueue correctly and also that I process the encoded buffer in the right wat... My code to setup audio recording: sample project https://github.com/vecter/Audio

问题 I am not the first to have this type of issue, however, I have no been able to solve it. I am encoding a LinearPCM to MP3 in iOS. It is working though I am experiencing clicks between each buffer. memset(&mEncodedBuffer, 0, sizeof(mEncodedBuffer)); int encodedBytes = lame_encode_buffer(gfp, (short*)inBuffer->mAudioData, NULL, inNumberPacketDescriptions, mEncodedBuffer, MP3_BUFFER_SIZE); NSData* data = [NSData dataWithBytes:mEncodedBuffer length:encodedBytes]; Then, I do the following with the

问题 If I know the URL of an MP3 file, what is the easiest/fastest way to get its length, bitrate, size, etc? How can I download just the ID3 tag part of the MP3 to get these details? 回答1: You will need to look at the ID3 tags in the mp3 file. Unless you keep track of the metadata you want somewhere else. To specifically get the Track length of the file you will need to look into the ID3 metadata tag for sure, specifically the 'TRCK' frame of the tag. To only download the ID3 Tag part, you must

问题 I'm trying to write a Python script for searching out duplicate mp3/4 files using the song's data as the base for comparison. My situation involves many mp3/4 files with similar file names, but different ID3 tags. At first I tried looping through and using md5 to find duplicate files (ignoring file names). This, of course, didn't work when the ID3 tags didn't match. As a result, I'm looking for a way to extract only the music data from an mp3/4 in order to run it through md5 and find any
