WaveLinkToAsio

This utility significantly reduces latency in the Elgato WaveLink software, making it more effective for use with StreamDeck +

API Reference

Start Script

  python main.py

The script default is to connect the Elgato WaveLink software to a SSL 2 interface. To use a different ASIO device, When it doesnt find the SSL it will then list out other ASIO devices copy it over in to the main.py and you should be good. Output

D:\GitLocal\wavelinkToASIO>python main.py
ERROR:root:Could not find the specified devices. Available ASIO devices are:
INFO:root:Device Index: 34, Device Name: Solid State Logic ASIO Driver

D:\GitLocal\wavelinkToASIO>

then for the main.py you would set...

  default_output_device_name = "Solid State Logic ASIO Driver"

• Elgato, Hopefully, this script will become obsolete as the software improves.

PyAudio ASIO Installation Guide

Standard PyAudio lacks ASIO support. For wavelinkToAsio to function, you must either compile PyAudio with ASIO support yourself or download the appropriate .whl file.

Prerequisites

• Python (matching the version of the PyAudio wheel file)
• pip (latest version)

Installation

1. Download the appropriate PyAudio .whl file from Christoph Gohlke's Pythonlibs repository. Select the file that matches your Python version and system architecture.

2. Launch your command-line interface of choice.

3. Use pip to install the downloaded file with the following command, replacing PyAudio‑0.2.11‑cp311‑cp311‑win_amd64.whl with the name of your downloaded file:

   python -m pip install PyAudio-0.2.11-cp311-cp311-win_amd64.whl

Roadmap and Performance Updates

Kernel Streaming Support

• Current: Limited to Windows WASAPI (fairly fast).
• Goal: Add Kernel Streaming (KS) support for improved latency.
• Note: Experiencing underflow problems at lower sample sizes (16). Hoping KS implementation will resolve this.

Frame Timing Information (Measured at 120fps externally)

• Wavelink: 21 frames, ~175 ms
• 512 off: 17 frames, ~141.67 ms
• 512 on: 13 frames, ~108.33 ms
• 32 off: 13 frames, ~108.33 ms
• 32 on: 7 frames, ~58.33 ms
• Control: 5 frames, ~41.67 ms
• Enabling 'Safe Mode' unexpectedly boosts performance and reduces latency?
• Measured on Win11 with I7 13700k an interface SSL2 with v5.58.05 drivers
