After each call to the LAME encoder the number of bytes in and out are sent to whatever event handler you've attached. Using (var reader = new (var writer = new reader.WaveFormat, 128, tag))Īs of v1.0.4 there is now an event ( MP3FileWriter.OnProgress)that you can use to get progress information during the encoding process. Probably a good idea to keep the size reasonable. The solution to the limit is to write the ID3 tags directly if they are too large for LAME to handle. LAME can't directly support ID3v2 tags greater than 32KB in size due to internal buffer size constraints, it does allow you to write your own ID3 tags. There are a lot of other bits of information that can potentially be stored in the ID3 tag, with all sorts of interesting ways of encoding the data.Īnd yes, you can add a cover image, in JPG, PNG or GIF format. The ID3TagData class is pretty simple right now, with only basic information support. The LameMP3FileWriter class now accepts an ID3TagData parameter, allowing you to supply some information that will be set as the ID3 tag on the MP3 file. On ASP.NET (Framework or Core) it is important to load the native DLL The method is called during LameDLLWrap assembly loading the first time a method that uses the Return true without attempting to load the DLL again. When the native DLL is loaded this way the handle is preserved and repeated calls to the method will LameDLL.LoadNativeDLL(hostEnvironment.ContentRootPath) Public IndexModel(IWebHostEnvironment hostEnvironment) Useful in ASP.NET and ASP.NET Core to resolve the native DLL in paths outside of the current directory The new (.) method in v1.1.3 allows you to specify a set of rootįolders to search for the native DLLs and load the correct version for the current architecture. Using (var writer = new WaveFileWriter(waveFileName, reader.WaveFormat)) Using (var reader = new Mp3FileReader(mp3FileName)) Public static void MP3ToWave(string mp3FileName, string waveFileName) Convert MP3 file to WAV using NAudio classes only Using (var writer = new LameMP3FileWriter(mp3FileName, reader.WaveFormat, bitRate)) Using (var reader = new AudioFileReader(waveFileName)) Public static void WaveToMP3(string waveFileName, string mp3FileName, int bitRate = 128) Convert WAV to MP3 using libmp3lame library Here is a very simple codec class to convert a WAV file to and from MP3: The LameMP3FileWriter class implements a Stream that encodes data written to it, writing the encoded MP3 data to either a file or a stream you provide. This will happen for example in ASP.NET projects. Please note that native library loading will fail if for any reason the application's binary path is not in the current search path. The LameDLLWrap project is the interface to both 32-bit and 64-bit version of the native DLLs, and is compiled for both targets.īoth versions are compiled into resources in .Īt runtime the version for the current process bit width is loaded from resources, which then references the appropriate native library. If you are compiling for a specific CPU target - x86 or 圆4 - then you only need to distribute the appropriate version. Includes both 32-bit and 64-bit versions of Windows native libmp3lame.dll (named libmp3lame.32.dll and libmp3lame.64.dll respectively), both of which will be copied to the output folder on build. It may function with Windows emulation layers but I have never tested this. IMPORTANT: Because this wraps Windows native DLLs it will not work on any other operating system. ![]() If you still can't find the file you need, you can leave a "message" on the webpage.Wrapper for libmp3lame.dll to add MP3 encoding support to NAudio 2.0 on Windows.If yes, please check the properties of these files, and you will know if the file you need is 32-bit or 64-bit. If you encounter this situation, check the file path to see whether there are any other files located in. There is a special case that, the operating system is a 64-bit system, but you are not sure whether the program is 32-bit or 64-bit. If your operating system is 32-bit, you must download 32-bit files, because 64-bit programs are unable to run in the 32-bit operating system. ![]() (Method: Click your original file, and then click on the right key to select "Properties" from the pop-up menu, you can see the version number of the files) If your original file is just corrupted but not lost, then please check the version number of your files. If you know MD5 value of the required files, it is the best approach to make choice Tip: How to correctly select the file you need
