add conda recipe for torchaudio

[faroit]

there are many issues with users having difficulties building torchaudio extension. Maybe it would be good to provide conda builds?

I could create a recipe if that would be helpful.

This is a good idea. @pjh5 is unfortunately away at the moment; I'm not sure what the most useful contribution we could make here is.

this seems reasonable to do. I have been doing some pre-work for this by adding lame support for sox in conda-forge: conda-forge/sox-feedstock#18

We need to setup torchaudio with Azure pipelines to auto-build and auto-upload torchaudio packages as well, and then we'll be golden.

cc: @kostmo @pjh5 if you guys have any instructions on how one can setup a new repo with the necessary azure build config / pipelines, that'd be helpful, we would also want to do this soon for torchvision

@soumith It's easy to use. Just write the yaml config file and it will work. Here is the document for this: https://docs.microsoft.com/zh-cn/azure/devops/pipelines/yaml-schema?view=azure-devops&tabs=schema. And here is our example: https://github.com/pytorch/builder/blob/master/windows/azure-pipelines.yml.

is there some progress on this? I think the number of issues related to users having problems to install sox are getting way too many ;-)
