This is the command audiotool that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
audiotool - manipulate audio data files.
audiotool -append [-offset=pos] target audiofiles...
audiotool -build [-encoding=codec] target audiofiles...
audiotool -chart [-silence=value] [-framing=msec] audiofiles...
audiotool -info audiofile
audiotool -notation audiofile [``new-string'']
audiotool -play audiofiles...
audiotool -soundcard [index]
audiotool -strip [-silence=value] [-framing=msec] audiofiles...
audiotool -trim [-silence=value] [-framing=msec] [-padding=frames] audiofiles...
Audiotool is used to copy, manipulate, and examine the contents of audio files. These
audio files may be raw headerless audio data or audio stored in common data files such as
.wav or .au files. In the near future audiotool will also support packetized audio files
such as .mp3 and .ogg.
appends the content of other audio files into an existing audio file. The offset
to save within the existing file may be specified. If nessisary the content of the
specified files will be re-encoded in the codec of the file being appended to.
-build Build a brand new audio file from scratch and then copy content from existing audio
files into it. The encoding of the new audio file will either be based on the file
extension, the audio file that is being copied into it, or by specifying the
encoding format directly.
-chart This is used to generate an energy chart profile of the audio file frame by frame.
A * indicates solid audio content, a ^ indicates what might be a lead or trailer
section of partial content, and a . indicates relative silence. Soon a autotrim
option will be added to audiotool to remove silent frames.
List all active codec objects. If you have plugins which are loaded that creates
codec objects which match a built-in codec, the plugin will be selected first.
-info The info command gives you basic information on the audio file, including what
format it is stored as, what codec the audio data is encoded in, how much data is
in the file, what the bit rate used is, etc.
Notation can be used to either set or display the annotation stored in audio files
which support annotations, such as .au and .wav files.
-play Plays the content of the audio file to the default system audio device (soundcard).
Play is supported on w32 and posix systems that support oss audio. Future work
will expand to additional platforms.
This simply returns the path to the plugins directory. All plugins are loaded with
Audio::init(). Plugins are not supported when building with static linkage.
-strip Strips out all silent frames from an audio file. Silent frames are those which
fall below a threashold and that have no peak impulse above the threashold.
-trim Removes leading and trailing "silence" from a file. The -padding option may be
used to add additional silent frames at the end of the file after it has been
trimed, as this may be needed for files that will later be used to join together
