Reaper reference

`reaper` command line tool

The `reaper` command line tool extracts F0 measurements from an audio file. It was written by David Talkin and is a successor to the `get_f0` command from the ESPS tools. Users of the [Berkeley Phonetics Machine] can install it with `sudo bpm-update reaper` command.

The `reaper` tool is not very heavily documented. To see the available options, run the command with no arguments:

``` reaper ```

The available options will be listed. You can also consult | the source repository for more information or to inspect the code.
