Initialization
Flags:
-
-S integer = Start the extract at the given sample number.
-
-Z integer = End the extract at the given sample number.
-
- Q integer = Extract given number of samples.
-
-T fpnum = Start the extract at the given time in seconds.
-
-E fpnum = End the extract at the given time in seconds.
-
-D fpnum = Extract given time in seconds.
-
-v = Verbose mode.
-
-R = Continually rewrite the header while writing soundfile (WAV/AIFF).
-
-H integer = Show a "heart-beat" to indicate progress, in style 1, 2 or 3.
-
-N = Alert call (usually ringing the bell) when finished.
-
-v = Verbose mode.
-
-o fname = output file name (default: test.wav)
Examples
The default values are
extractor -S 0 -Z end-of-file -otest
For example
extractor -S 10234 -D 2.13 in.aiff -o out.wav
This creates a new sound file taken from sample 10234 and lasting 2.13 seconds.
Here is a complete example of the extractor utility. It uses the file extractor.csd.
