New: Hang Loose DSP Processor

[mitchco]

Any specs for the analog output performance.

Please note HLP is not a DAC.

the filtering is done by the dsp so that the raspberry pis could be free to run VSTs?

The SHARC DSP can be used for low level signal processing as required and for additional flexibility. However, the CM5 powers the main DSP processing in software using HL-DSP-Suite which includes a host application to host VST3's.

2) when will the 16 channel with aes67 be out?
3) 32 channel?

This year But check the HLP product page for status updates.

I started to post this here

Raspberry Pi 5 and CM5 as players and convolvers with lotsa analog ports

I want to get into Raspberry Pi audio in a big way, but total noob here. I have no interest in AVR decoding or expensive closed-algorithm hardware DSP boxen. I'm excited by the power of Pi5 and now even more by the CM5's modular approach, after seeing that is the HLC platform! Please, those...

Any CM5-savvy members willing to help outline what's needed to get ready to get started, please advise?

> Did you see this piece where Archimago used Accurate Sound's Hang Loose Convolver Multichannel on low power Mini PC?

I will look at that.

But I am building an overkill large & powerful PC for testing purposes, measurements creating filters etc

That will end up as NAS out in the garage, too big hot & noisy for the listeing space.

At 12+ channels, the USB interfaces are too expensive for me, so will try old PCIe and Firewire ones that I can afford.

If I can get these to also work on RPI5 then I hope that can handle what I need, convolving full time, maybe in conjunctiin with DSPi units.

But I'd rather not set up another PC unless that proves truly necessary, doubtful a miniPC will run those host-card based interfaces, unless I do something like OCuLink to external boxen.

Maybe start your own thread. This one is about HL DSP Processor hardware - looking forward to seeing it!

@mitchco:

Will the HLP have any CEC support on the HDMI input?

Also, I saw that the convolver has an API, does/will Hang Loose Host also have one?

@kifeep

CEC control - power and volume

HLHost will adopt HLC’s expanded audio settings and routing API, adding unified support for UPnP I/O, managed ALSA output, multichannel configuration, and new DSD output path.

More technical details will follow closer to release next month.

Wow those are tremendous developments for what is already a stellar product family, I sincerely hope you and yours prosper from these ongoing contributions to our community!

That’s awesome. Looking forward to seeing those.

@mitchco I'm seriously considering purchasing one of these when they're available. I'd just like to explicitly confirm something implied in the specs:

HDMI Audio​

• Up to 8-channel 192kHz/24bit PCM and 6-channel DSD64 audio extraction

USB Audio​

• Up to 8-channel IN and OUT configuration

Features​

• Any input can be routed to any output (e.g. TOSLINK in -> DSP -> USB out)

So if input is HDMI (LPCM) and output is USB to an 8-channel DAC, then full 8-in / 8-out processing is possible, correct?

If confirmed, you might consider changing the "stereo" model designation. I expect some folks stop reading when they see that, and it confuses me just enough to ask this question.

I don't think you can play 4k Blu-rays on PC any more, either.
If my fuzzy memory serves me correctly, your CPU needs something called SGX (software guard extension) that was ditched some time ago. Plus an old version of Windows.
Unfortunately you need a recent CPU with TPM2 and UEFI secure boot in order to run Win 11.

Whatever software that I have set up for many years now, works with Blue Ray. I do not know about 4K on the laptop.
Not being computer literate (I can build one but not program one), I am not sure of the programs that make it work, as they were installed, modded if needed, by people that I no longer have access to.
Not going to Windows 11. Their requirements kicked my out of that, anyway. I'll find another way.

I have found that I have a laser out, so that has to be taken care of, no matter the software!
