While it does not use ffmpeg as you indicate in the title that you want to do, to convert a FLAC file to .wav you can simply pass it through flac using the --decode ( -d) switch. flac --decode input.flac will produce input.wav as output, containing the same audio data.

NOTE: Depending on the type of CPU in your Asterisk server, if you hear a high-pitched screech instead of your audio file, you may need to use the --endian big switch like this: sox input.wav --rate 8000 --channels 1 --type raw --endian big output.sln lowpass 3400 highpass 300. ulaw did not produce results that sounded as good as sln. Launch the tool, add your video files, choose output format, and click convert. The program will use as many cores as possible to speed up the conversion if you have huge number of files to process. For KDE users, there’s SoundKonverter (install it from Ubuntu Software) with more features including rapping CD to mp3. First, convert the MP3 to WAV file. Then, For u-law: sox -V output.wav -r 8000 -c 1 -t ul result.ulaw. For GSM: sox output.wav -r 8000 -c 1 result.gsm resample -ql. Pre-converting your input sound files usually give much better results than using internal modules for transcoding.
