I want to find a way to create a new MP4 container and add an MP3 file into it. Whether the MP3 file is to be encoded or not does not matter to me. Is there any easy way to do this without using ffmpeg? I have found the following example for muxing:
android - How to mux audio file and video file?
Though, it has issues and also it is supposed to mux the audio file into an existing video.
Can someone point me to a guide or at least in the right direction to accomplish what I need?
U can do this using MediaCodec and MediaMuxer but right now i think mp3 is not supported u should first decode mp3 to wav and encode to supported format like aac using MediaExtractor and MediaCodec and then u can add to mp4 container using Muxer.

I have created an application but it is only support .wav files to convert audio to text. It is not showing any answers when giving .mp3 files .. I am using sphinx for to convert audio files to text. My question is that why it is not converting to text from .MP3?
As it is specified in the CMU Sphinx documents, only the linear PCM WAV audio format is accept by its speech recognizer. Therefore, any MP3 audio file will be decoded to obtain the linear PCM format, of 16khz sampling rate, 16bit/frame, little-endian and one channel (mono).
This decoding is achieved by the Tarsos Transcoder 1.2. This library uses many Apache utilities, therefore beside the TarsosTranscoder.jar, mp3plugin.jar also has to be included in the project building path.
Is there a way to convert a mp3 audio file into a wav audio file in java without using external libraries?
If you want to tell java "hey, convert an mp3 file", it won't do that, because it isn't made for mp3.
If, however, you are comfortable with using a purely java library, then check out JLayer. I have used it myself and it worked wonderfully.
I have a java program that plays .wav files by putting them into Clips. I wanted to know if there was a way (without JLayer or any external libraries) to convert an mp3 file into a wav file that I could put into a Clip? Thanks
Which audio format would provide the least lossy conversion into mp3 and ogg through ffmpeg.
I am tending towards wav, but I would like to make sure.
Also, I am using the SDK java audio applet to allow users to upload. Does anyone know if there are any issues with this applet, or if there is a better option out there?
Obviously, uploading files already in MP3 and OGG format would provide the least lossy conversion since you don't need to convert at all.
About the SDK java audio applet: Is this really needed? You can also upload a file using just a HTML form and PHP.
FLAC is lossless, and so is WAV. FLAC is smaller than WAV. If you need something that you will be converting into multiple formats, opt for a lossless format.
