[linux-audio-user] AIFF files batch-slicing

Hi, I need to automate a process for slicing audio files in AIFF format on multiple files everytime perfect silences are met (zero-amplitude). This should be multiplatform (Linux/Mac/Win) and minimal (no GUI, only command-lines: one should just have to launch the script / program). The handling of standard UNIX commands like changing and listing directories, moving or renaming files... is requested. I've thought of Octave or Scilab but I couldn't find their Mac version and the AIFF file-handling wasn't that great. Alternatively, I could write a shell script, but I think I'd still need a piece of software to understand the audio files and determine whether it's silent or not. Sox? At last, I could write my own C software, bearing in mind it may need customizing along the OS where it is compiled... Any idea? Cheers, Christian Frisson
