Real-time convolution reverb using impulse response audio files. See settings.txt for configuration
This repo is using git-lfs for the storage of binary files(wav impulse responses). The following should automatically download the files during cloning.
apt install git-lfs
git lfs install
git clone [email protected]:limitz/cuda-audio
- CUDA, tested on 10.2 (JetPack 4.6) and 11.something
- CUFFT, should be included with CUDA
- JACK, Jack daemon and development files.
- External Audio Interface (I have a focusrite scarlett)
- USB Midi controller
I've had some issues with jack install and I believe I have jack2 running on the Jetson, and jack1 on my laptop. Don't get discouraged if you find yourself rebooting your system a few times and tweaking parameters while dodging error messages.
On Jetson nano I set Sample Rate: 44100 Frames/Period: 256 Periods/Buffer: 2. system still under test
In order to properly run jack on the Jetson, you may want to modify and rebuild the L4T kernel. I've done this using the scripts found here: https://github.com/JetsonHacksNano/buildKernelAndModules
After downloading the sources, use editConfig to go into the config menu and enable ALSA SEQ support (under sound drivers somewhere).
There are some convenience scripts in the jetson folder. floorit is a MUST before running the application.
- scripts/jfloorit - enable maximum performance
- scripts/chillout - disable maximum performance
- scripts/ghostme - enable X/OpenGL applications without display attached
