ffmpeg creating broken 0 byte files

[Joe]

I am not super technical, but I will try and provide the best description of the issue below.

Summary of the bug:
How to reproduce: I am trying to reduce a large wav audio file (792MB). I use powershell to run the below command.

% ffmpeg -i input audiofile.wav -acodec libvorbis -b:a 320k output.ogg

ffmpeg version 4.4.1-full_build-www.gyan.dev Copyright (c) 2000-2021 the FFmpeg developers
  built with gcc 11.2.0 (Rev1, Built by MSYS2 project)

The Full output I get is this

Guessed Channel Layout for Input Stream #0.0 : stereo
Input #0, wav, from 'Forest.wav':
  Metadata:

Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Conversion failed!

The file it creates is a 0 byte file that can't be deleted except for cmd admin commands.

can't be deleted except for cmd admin commands.

What this has to do with anything?

The error message you are getting is accurate, you have provided an invalid combination of parameters which libvorbis does not support. Either use a sample rate less than 50000 or a non-fixed bitrate.
