HP-UX audio
Yesterday I installed the audio option for my C8000 and it took me only 5 minutes to figure it out.
Good old times when things were properly documented.

At work, it gets me so mad that the vendors of basic infrastructure services publish new versions every 2nd week, the documentation is awful or inexistent and sometimes the behaviour of an existing feature changes. AAAAA

A quick visit to SAM help, then a quick visit to the Audio Mixer help, adding the driver to the kernel and rebooting and I was good to go.

The quality is awful, though. The card (or the wiring of the jacks) is so poorly grounded that you hear the whining on the headphones every time the network card sends data or the hard drive reads anything.

Someone on stackexchange had proposed getting QuakeGL to run under HP-UX - I will try to find the person out and see how the effort is going.

RE: HP-UX audio
That always seems to be the sticking point with vintage *nix audio - even if it works, what is there to use it with...?

S'pose it's probably possible to build PureData for it, maybe...?

RE: HP-UX audio
I have no idea if there's software or not. I guess you can listen to MP3s while you CAD or code. =)

I got it to work under Linux, although my MP3 player is crashing. The repository I used to get "stable" Debian 10 packages went offline a month ago and now I'm on sid - it's completely broken.

Although - I remember reading somewhere that the Octane has really low latency with optical audio, so I will hook up my 8-channel DAT thingy to it eventually.
Just can't imagine anyone using such a loud computer as audio workstation.

RE: HP-UX audio
Not to change the subject but under the question of UNIX audio work, I have an Indigo2 that was claimed to be used by FOX studios to mix the audio for the Simpsons TV Show back in the mid/late 90’s (at least that was what they previous owner told me and the FOX asset sticker is still on it).

I seems under most (all?) SGI hardware running Irix there is a bit of an audio capture interval guarantee of like 3ms? I cannot find the info I read a few years ago but it turned out that yes, mixing many audio streams on SGI was a thing because you could be certain that your audio capture rate (per recording to the hardware) was no longer than 3ms under normal usage.

I guess Windows-based audio did (somewhat still does) have an issue where a busy CPU or system task can defer a driver from properly triggering in time for a recording and can get issues.

So while SGIs do not have a special programmable DSP chip like NeXT, they somehow did make it reliable enough for sound capture and music production tasks back in the day.

Something you don’t here about on SGIs.

RE: HP-UX audio
3ms is extremely excellent.

I have some old FireWire interfaces (I own the whole Focusrite Saffire range) and yes, Macs used to be best because in Windows the latency was always higher and USB interfaces make matters worse. I have an old Mac Pro in a garage and I record there with my friends. No reason to throw away perfectly functional interfaces because the manufacturer won't upgrade the drivers. With a 1,1 Mac Pro, I get much better latencies under OS X compared to WinXP or 7, especially if you are doing live monitoring with effects applied.

Also, if I recall correctly, when Microsoft changed the audio model from XP to Vista/7, it broke a lot of things. I remember spending days troubleshooting Avaya IP Softphones back in the day. And yes, the early Win7 drives sucked and were extremely laggy.

Do you have any suggestions of audio recording apps I could try in my Octane?
