If you think it's C states and Turbo Boost, there are kernel options to turn those off. There was a thread where someone tried this on a laptop and it led to overheating. If you're using a desktop with adequate cooling it should be OK. intel_idle.max_cstate=0 intel_pstate=disable processor.max_cstat...

No, it's controlling the DSP mixer built into the Scarlett. It's really for setting up monitor mixes, so it's a nice extra, but not essential.

Check the hardware Do all the lights come on? Are all the knobs good? Are all the sockets good? Check it's recognised $ lsusb Check ALSA sees it $ aplay -l Check it makes sound $ speaker-test -D plughw:<device name> A first generation Scarlett seems quite good for Linux as there are a lot of contro...

Actually, thinking about it the clue is in the name -- 404. Four ins, four outs. The reason there is also a main out is that the main out can be used to monitor the input -- zero latency monitoring, so called. There is a mix control on the front of the 404 that blends the input with the playback fro...

We're maybe getting a bit confused here. Jack has a Focusrite 18i8 gen 1. Yes, it only has one stereo pair as an output called 'monitor out'. https://i.postimg.cc/PxYxw9hM/18i8back.webp The Behringer 404HD does have more than two outputs. Yes, the main out is available on XLR or TRS jack, but it wou...

... Now about those balanced in- and outputs on an audio device... Behringer is not gonna cut it for you I think, but I always thought that Focusrite was a bit more "professional". ... The Behringer UMC404HD does have balanced inputs and outputs. https://i.postimg.cc/fW9PNkPS/UMC404-HDspe...

arecord tells you the cards that are available. To see the inputs and outputs use alsamixer from a command line or I think in Ubuntu Studio there is an app qasmixer which is a gui for alsamixer. I'm pretty sure ALSA will see all the inputs and outputs, including S/PDIF.

EBU R 128 is about loudness. It might look like some digital interconnect format, like AES3, but it's not. Basically LUFS -23, dBTP -1. Fortunately x42 wrote us an EBU R 128 meter. https://i.postimg.cc/yYRsXnYr/x42-EBU128.png Whatever the standard is in the US, it will simply be different values of ...

... Two instances of Stereo Tool ( https://www.thimeo.com/stereo-tool/ are running on the PC I'm trying to configure: one provides the aggressively-processed FM signal, the other provides the less-aggressive one.

... At least two independent digital-to-analog converters, so each instance of Stereo Tool has its own output (not so easy?) A common clock running the adc and the two dacs so the two output devices don't drift out of sync with each other and we run into buffer issues (not so easy?) ... An audio in...

To load threadirqs edit etc/default/grub and add threadirqs to the line

GRUB_CMDLINE_LINUX_DEFAULT=

Then update grub with

Code: Select all

$ sudo grub-mkconfig -o /boot/grub/grub.cfg

Sadly not. There is a fuss at the moment around ChatGPT, and similar technologies. I would think on these as 'neural networks', or 'machine learning'. AI is a bit of a strong term, as they are only as good as the training data, which for ChatGPT was ... the entire internet, or 45TB of it at least. C...

G for gain is used in engineering. G is the name of the parameter, not a unit. Gain is defined as

Gain = V_out (Volts)/V_in (Volts)

The Volts cancel out, and gain is a number. I think "pure logarithmic units" are similarly a number and not a unit.

... Threading IRQ's may have an effect. Just try it with and without. Only has effect on generic kernels though. If you already run a low-latency kernel this option is useless, or so I've read. ...
