    audio manipulation software, looking for command line tools in

    i am looking for command line tools in audio manipulation software. i have an audio file (in lossless .flac format) with a sample rate of 44100 Hz. i would like to "play" it (and record it to a new file) at half speed, including the frequency reduction, and store the result also in the same format (.flac), but without the 22050 Hz stepping noise that will interfere with other manipulations. i managed to play it at a sample rate of 22050 Hz and that sounded like what i want. but i don't want a 22050 Hz file; i want a clean 44100 Hz file. so, i am looking for audio manipulation software that can do this ... without trying to keep the frequency the same. it's like recording it on an analog reel-to-reel tape at 7.5 IPS and calling it 3.75 IPS. does anyone know of command line tools that can do this?

    Sox often described as the Swiss-knife of audio is the one you want here apart from/or ffmpeg

    Code:
    sudo apt-get install sox libsox-fmt-all
