Hi - I have been keeping Inguz DSP going for the last couple of years,
and in doing so learnt a lot about the LMS plugin architecture. I am
thinking of writing a new plugin based off CamillaDSP, but want to gauge
the appetite before I get in too deep.
Inguz
Features
- 32 bit audio processing engine
- 2 to 31 frequency Equaliser using ISO standard curves
- Retains stream frequency rate through the pipeline and will match
bit depth to player (16 bit / 24 bit)
- Channel Delay; Matrix Impulses (Think specialisation); Balance;
Filter Limits; and Loudness (perversely called quietness)
- FIR Convolution Engine
- Cross platform using .net Core 6
Downside
- binary size approx 30 MB
- relatively processor intensive e.g. spikes every 10 seconds @ 2 -
25% CPU depending on processor.
- designed to process 2 channel audio only
- Feature locked - I consider it feature locked as I am not
considering writing enhancements to the core engine.
I can add usability features to the UI, but the capability of the
processing engine are not going to change.
In contrast Camilla DSP
- 64 bit audio processing engine
- Configurable parametric EQ, which could also be setup as 2 to 31
frequency Equaliser using ISO standard curves
- Almost every conceivable filter type and processing is possible
- FIR Convolution Engine
- Cross platform using pre-compiled Rust
- binary size approx 3 MB
- processing is as fast (low cpu usage) as you are going to get
- Has it's own python and web based UI
- multi-channel
Downside
- Would need to be at fixed sample rate across the pipeline
- Almost every conceivable filter type and processing is possible,
which may be unmanageable and I haven't checked everything!
- multi-channel
The plugin will
Setup the audio pipeline
install the binaries appropriately
create folders for saving configuration files
For the User Interface
I had considered writing a wrapper for CamillaDSP's own UI for now and
then enabling presets based off saved YAML files, but I think the
install and maintenance will be a nightmare.
So I will enable the convolution engine initially off saved wav files
Enable equaliser/parametric eq.
Simple features like delay; balance etc
2 channel only
frequency rate to be set on a per player basis.
My thinking is that this will cover 80 to 90 percent of use cases, and
for anything more complex the user could import a pregenerated YAML file
and use that as a preset.
Any thoughts on the above. Any burning ideas for features?
