dawnet-client 0.7.1

DAWNet client enables remote execution of python code triggered from a DAW.

DAWNet

DAWNet is a DAW (digit audio workstation) plugin that connects to a remote Google Colab or Script. A user can send audio files from the plugin for remote processing. Hence, perform computationally expensive tasks such as text-2-audio or stem separation without leaving the DAW.

dawnet-client

The DAWNet client (this repo) is a python3 pip package. It is used to create DAWNet remotes. The client is responsible for moving data and files backand forth from the plugin (and server). The client allows a user to register python functions with the DAWNet discovery server. After a function has been registered it can then be triggered remotely from `DAWNet plugin.

::: warning NOTE: The plugin is in an active, pre-alpha state. It has only been tested on Ableton 11 on MAC M1. :::

Installation

pip install dawnet-client --upgrade

Tests

from the root of the source code dir run:

pip uninstall dawnet-client -y && pip install -e . && pytest -s

Usage

This is a simple example of a DAWNet remote script created using the dawnet-client. The script defines an arbitrary function that takes two arguments, an integer and a DAWNetFilePath. The function is registered with the DAWNet discovery server. The script then connects to the DAWNet discovery server and waits for a remote trigger.

# The token is generated by the DAWNet plugin.  
# It is used by the discovery server to associate the remote with the plugin.
TOKEN="0715c132-0b31-406e-b562-9206c479a48a" 

# The registered method can be named anything. Note: the method must be `async`.  
# All parameters must be type hinted.  
# 4 parameter types are supported: int, float, str, DAWNetFilePath
# DAWNetFilePath is a special type. When the file is sent to the remote, it is intercepted by the system and 
# transported to a temp dir on the remote.  In this case the variable `b` is local path to the file.

# The `ui_param` is an optional decorator. It is used to define how the parameter input UI will be rendered in the plugin.  
# If the decorator is not used, the parameter will be rendered as a text input field.

CONFIGURATION:

Note: If the following environment variables are not set, the client will use the default values. The default values will point to the public DAWNet server. If you wish to host your own instance you will need to configure the following environment variables.

export DN_CLIENT_API_BASE_URL='http://localhost:8081'
export DN_CLIENT_SOCKET_IP='0.0.0.0'
export DN_CLIENT_SOCKET_PORT='8765'
export DN_CLIENT_SENTRY_API_KEY='XXX'
