HLC is designed to run on any platform and work with any audio source. For Mac, there is a standalone app plus VST3 and AU plugins. On Windows there is a standalone app and VST3 plugin. Shortly will be available on popular distros of Linux, with standalone app and VST3 plugin followed by iOS and Android apps. That's 9 convolvers running on the majority of platforms for a one time perpetual license of $129 with with free upgrades.
HLC is a fully fledged DSP engine. Getting easy to use convolution on the majority of platforms is phase 1 of this release, in addition to it's specialized capability. There will be other "DSP" features moving forward that I am not ready to disclose yet.
Dear
@mitchco , I greatly value your numerous contributions to the DSP scene.
I want to take this opportunity to consult you about something I have been wanting to do for years, and maybe it will be of interest to other members. Besides enjoying the correct and accurate reproduction of music, I also love movies and think that at certain times the soundtrack far exceeds 50% of the experience. It takes some work to implement DSP the right way on 2.0, 2.1, 2.2 systems, but this becomes exponentially tougher for multichannel systems.
Since the birth of Blu-Ray we have the masters of these lossless soundtracks, either in Dolby Digital True HD, or DTS HD MA. It is therefore natural that we want to apply correction to all channels of the system and take advantage of these tracks.
The strategy I plan to follow is as follows:
- Have physical Blu Ray and UHD discs, movies in Mkv, h265, or BD Folders.
- Use an HTPC for video playback and DSP application (must have Intel processor compatible with SGX, and be of sixth to tenth generation to play UHD)
- Have an external UHD reader of these disks connected to the HTPC.
- Connect HTPC via USB-C to a MOTU UltraLite-mk5, to be used as a transparent multichannel DAC (it has 10 fully-routable line outs with 112dB SINAD)
- Connect MOTU outputs to multichannel inputs of SOTA AVR to be used purely as an amplifier.
The playback of UHD Blu-Ray discs with menu included can be performed with JRiver (from version 24, the current version is 27 and 28 in development), and also with PowerDVD 21.
The difference is that JRiver integrates a Convolver and DSP functions, while PowerDVD 21 does not.
My DSP experience is summarized to PEQ filters generated with REW.
I am new in the world of convolution.
So I would like to know if HLC would be useful or not for my applications and sound chain. What I have clear for the moment is that I will have to take measurements with my UMIK and create the filters with one of these: Acourate, Audiolense, Focus Fidelity.
The functionality of being able to switch between different filters in real-time is great and very useful, but it is not my main motivation, since I have very well-defined target curves. I find it very interesting in its specifications and your comments, that it is supposed to be
system-wide, so it would apply to the sound output of any program (although I imagine that maybe in Windows it needs some routing configuration).
So this would mean that when playing UHD discs, using HLC I would not be limited to having to use JRiver convolver, since HLC itself is a convolution engine? And above all, if we talk about system-wide, this would also solve any other application of the HTPC either YouTube audio, any streaming app like Netflix, Prime Video, Disney+, and any player like saying VLC or Foobar ?
In short, my intrigue is to know and understand if after designing the corrections for each channel,
HLC would be the host and engine of the convolution filters and therefore the fixes would be applied to any output generated by any program within Windows OS. So I would avoid having to configure such programs individually (if they allow convolution) or having to resort to plug-ins.
