More information please.


Huh?

I gather you are targeting low end CPUs


I don’t think there is a target. It should happily run on very fast machines as well.

@mitchco Very glad to see this coming up! Can't say enough good things about you. Your Computer Audiophile Acourate articles inspired me to go digitally active an into Acourate, which I still use. That opened the door into DIY speakers, and your ebook was essential to getting a better grasp on measurements and use of Acourate. And you have always been very helpful on email exchanges. Outstanding member of this community!

 

Where does HLC fit into my system? I have Roon Core in a PC convolving filters to send 4-way stereo to a headless AudioPC with Roon Bridge at the living room, and I operate Roon from the phone app. I listen to files in my library in Roon Core PC and also Tidal streaming into Roon in that PC. I guess HLC plugs into Roon, takes the feed from Roon that is actually Tidal stream or my music files, convolves it with the selected filter, and outputs into Roon again to be sent to Roon Bridge on the AudioPC?

 

Is there a phone app to manage this or should I be at the Roon Core machine (Teamviewer can solve that), or does it integrate with Roon app?

 

Looking forward to learn more! Congrats again!!

 

Best,

Horacio

 

Hi Horacio, good to hear from you! I hope all is well.

 

Currently, HLC standalone app uses either VB-Virtual Audio cable on Windows or BlackHole on the Mac to "loopback" the output of Roon into the input of HLC and the output of HLC to your DAC. This is a 32 bit float lossless connection. Unfortunately, Roon does not support the VST plugin standard, so this is the current method of connection. I am working on options. Also note HLC processes 2 channel at the moment, but will be MCH soon. 

 

Kind regards,

Mitch

Hi @cfishersorry no info yet, but working on it. Re: HLC, the advantage is to determine which filter you prefer as I will be releasing a "set" of filters. One will be "neutral" and others will have a little more or less bass. more or less treble relative to neutral. The design behind this will come later, but by switching through the filters, one will likely be preferred.

Thanks to Mitch for all his work at Audiophilestyle. This lead me to use Acourate for xover and correction. And I am not looking back! just wonderfull.

It looks like Mitch will make a multi channel version in the future.

So my question is: will it then with the HLC be possible to use say 4ch VST3 files in Audirvana and making the output routing here to get it to work with the Merging Anubis, as I am doing nowadays with Audirvana>AcourateConvolver>Anubis? if yes, cant wait!

Has VST3 as many taps as AcourateConvolver?

Hey Michael, yes available on Linux soon. I just need the Linux distro and supported C++ compiler to target a release on.

So If SGC (Small Green Computer) accepts, this SW could be implementere in the Sonictransporter ?

Hi @Jorgenthanks for the kind words. The answer to your question is yes and yes :-) HLC VST3 and standalone app will run as many taps as can be output from Acourate, Audiolense and Focus Fidelity DSP software programs. Typical output is 65,536 or 131,072 taps.

 

Kind regards, Mitch

wonderfull, please let me know when your Multichannel HLC is availble. These days I am playing with the new Audirvana Studio which to my ears is even more transparent than the previous 3.5. So right now in Audirvana I upscale the stereo signal and sent it to the AcourateConvolver. With your VST3 files the stereo signal goes through the VST3 for being processed and then upscaled right before going to DAC ? if it is an advantage the signal sent to the DAC could then be a DSD or DXD signal? Merging Technologies likes DSD and DXD. Never tried, but in another simple setup I use a RME ADI2 dac and here I prefer PCM to DSD.

Best  regards,

Jorgen

Hi Jorgen, yes HLC is plugged in before the resampler.

HLC can be compiled to run on any mainstream Linux distributions is all I can say.


@agillis

Hi Andrew.
I like to suggest you looking into the possibility to implement this SW in the SonicOrbiter OS. 
I think it will add a lot of value.

HLC looks like a GUI application that requires a desktop OS such as Windows. Does it run embedded with no screen? That would be required to run on an "headless" device like a sonicTransporter.

It can run on anything. I’m guessing a web interface would work.

Is it possible to import files from Multisub optimizer  or Minidsp?

Hi @dziemian I don't know the filter file format for Multisub optimizer or miniDSP. I know folks use REW or rePhase to import filters and convert to another file format... HLC takes stereo 32 bit float .wav files either standalone or bundled in a zip.

Hi @mitchco  I was wondering if it is possible to use your convolver instead of minidsp hardware to store biquads generated by REW, Multisub optimizer, speaker's eq etc. The biquads look like following example...

 

biquad1,
b0=0.999848250832693,
b1=-1.999425176367626,
b2=0.999595318179774,
a1=1.999425176367626,
a2=-0.999443569012467,
biquad2,
b0=0.999765951342055,
b1=-1.997806523979884,
b2=0.998060158745793,
a1=1.997806523979884,
a2=-0.997826110087849,
