In version 1.2b1, Qt has been upgraded to 6.7.0, which added a new window style windows11 that is not stable enough and has been set to default on Windows by Qt developers. In 1.2b2, the default style on Windows has been set back to windowsvista, but this will only take effect if you are using Demucs-GUI the first on this computer.

The original pre-release file Demucs-GUI_1.3a1_cuda_mkl.7z has a bug that all output audio would be full of NaN. I've updated the file at 2024-10-23 14:29 GMT and the old one has been renamed to Demucs-GUI_1.3a1_cuda_mkl_ALL_NAN.7z

About the files:

• Demucs-GUI_1.3a1_cpu.7z: For Windows users without accelerators (e.g. GPU).
• Demucs-GUI_1.3a1_cuda_mkl.7z: For Windows users with NVIDIA GPU (whose compute capability is greater than 3.5) or Intel GPU (Intel Arc & Intel Xe).
• Demucs-GUI_1.3a1_macOS_x86_64_Rosetta2.dmg: For macOS users (Both Intel Mac and Apple Silicon Mac). You may need to install Rosetta 2 on Apple Silicon Mac. MPS acceleration is available on Apple Silicon Mac.
• Demucs-GUI_1.3a1_macOS_ARM64.dmg: For macOS users with Apple Silicon CPU. MPS acceleration is available.

Updates

1. Allow adding URL(s) as input, which will uses FFMpeg to read the audio
2. Automatically fill in the clipboard if you've copied a URL
3. Will use SoXR VHQ resampler as default when using FFMpeg to read audio
4. Added {host} and {0}, {1}, ... to the output file name variables (refer to usage for more details)
5. Allow enabling debug using environment variable
6. Added a simple debug console
7. Added support for Intel Extension for PyTorch 2.1.40+xpu
8. Allow changing options and retry when failed to save output audio

Fixes

1. Will open AOT documentation on the main branch instead of develop branch
2. No longer relies on wmic to get GPU information as Windows 11 24H2 has removed it. Used PowerShell to call Get-CimInstance instead

Known issues

1. CPU usage will stuck at 100% when separating, even running on GPU

Fixes

2. Added diffq as a requirement so quantized models can be used
3. Fix segment length may greater than max available length which will cause an error
4. Will only warn the user once if output file name and FFMpeg command may illegal

1.1a1

1.1a1

For Apple Silicon users: please use Demucs-GUI_1.1a1_macOS_x86_64_Rosetta2.dmg due to a bug mentioned in README. It can reach 25% performance compared with native ARM64 software if you separate an audio with CPU, but MPS acceleration is available and will not affect the accelerated speed.

Updates

1. Use the new tabbed UI
2. Add new option: separate once added to the queue
3. Save settings history for separate-once-added, file format, save location and clip mode

Fixes

1. Will show download progress if a remote model is not downloaded

In previous versions, Demucs-GUI will not change the default torch hub cache dir. However, from this version, all new models will be downloaded to Demucs-GUI.config.dir/pretrained/checkpoints, without copying the old ones there. So you need to copy it manually if you still need those models.

2. Fix auto check updates doesn't work
3. Fix model info can't be shown completely sometimes
