问题 I need to convert a flac file to a wav file without changing sample rate and bit depth. As far as I know changing these properties may distort the audio, so how do i specify them not to be changed? Also, is there any way to prevent metadata to be written to the output file? 回答1: As rogerdpack commented, the command line: ffmpeg -i inputfile.flac output.wav should do exactly what you want. Addressing your concerns about keeping the resulting audio intact, FLAC is a lossless format and decoding

Detect if a file is an MP3 file?

问题 I'm writing a C++ library for decoding and encoding audio between different formats/codecs. I have a routine for quickly detecting the format before loading the required codec library. For WAV files one can simple look for the ASCII values "RIFF" and "WAVE" at the start of the file. The same applies to FLAC, we can simply read in the first 4 bytes, which will be "fLaC". But how can I quickly detect if a file is MP3? I can't rely on the file extension. I also can't try to decode the first MP3

EDIT: Incorporated the changed uv001 's answer. I can only find that ICS 4.0 support decoding of FLAC, but encode. I need some encoder to convert wav to flac, but currenty I can't find it. I find there is a jFlac avaible , but I don't know how to use this library, just simply convert the files. Could anyone give me a hand on it? Today, I just some idea by myself, with using the JavaFlacEncoder. and it works for certain bitrates of WAV. I changed the value into a hard coding value in which it is working now. /* * Copyright (C) 2010 Preston Lacey http://javaflacencoder.sourceforge.net/ * All
