问题 I learned how to encode wav into an mp3 using lame_encode_buffer_interleaved from this question: Is there any LAME c++ wraper\simplifier (working on Linux Mac and Win from pure code)? Now I want to decode the mp3 back into wav. I know there's lame_decode but I don't know how to use it since it requires two pcm buffers ( pcm_l and pcm_r ). I don't understand how to put them together into a well-formed wav file, because I don't really know how they works. Now can someone provide a simple

问题 Specifically, I need to automate the encoding of audio files into mp3 with LAME. You don't need to know LAME to answer this, I could be talking about svn or some other program.. I know how to use LAME on the command line to do this, for one file at a time. I would like to do this via a php script however, so I can convert a bunch at once (for instance, all the files in a directory) So what I am confused about, is how I should invoke the program, LAME. I could definitely use shell_exec() http:

Google Chrome no longer plays certain audio files

问题 Since the update to v45, Chrome seems to no longer play select MP3 files. This is not across the board, and some other MP3 files still play. Chrome v44 displayed no issues and played all the files. This issue is common across many computers running various editions of Windows (in both 32 and 64 bit), and rolling back will allow the files to play. This however is not a viable solution for the client PCs, nor suitable going forwards. Upon inspecting the files themselves, I am unable to note any

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

Clicks while using LAME to encode from PCM to MP3 in iOS

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 I'm trying to follow the tutorial located at the following location http://developer.samsung.com/android/technical-docs/Porting-and-using-LAME-MP3-on-Android-with-JNI The gist of this is that it allows one to use the LAME MP3 encoder with JNI. I followed each of the steps mentioned in the tutorial. My project is located at C:\workspace\ and is called 'LAME_Test'. Per the section labeled Compilation with NDK in the tutorial, I went ahead and made a makefile called 'Android.mk' as is enclosed

How do can I use LAME to encode an wav to an mp3 c#

问题 I am currently using NAudio to capture the sound and it only creates a wav file. I am looking for a way to encode it to an mp3 before saving the file. I found LAME but when ever i try to add the lame_enc.dll file it says "A reference could not be added. Please make sure the file is accessible, and that is a valid assembly or COM component". Any help would be appreciated. 回答1: Easiest way in .Net 4.0: Use the visual studio Nuget Package manager console: Install-Package NAudio.Lame Code Snip:
