…and it was nice while it lasted. The 2025 series from LG (C5/G5) dropped support for DTS passthrough over ARC… sigh… This is incredibly frustrating when you realize there can be no technical reason for this: passthrough does not require any processing, it's literally just copying bits!

CAudioLimiter is, as the name implies, a soft limiter. It will turn 0 dBFS hard clipping into soft clipping. So yes, in that sense, it can "get rid of clipping". That's precisely what it's designed to do (although it's normally supposed to handle mixing- or APO-induced clipping, not clipping in...

It does. WASAPI Exclusive bypasses the entire Windows Audio Engine (behind the scenes it goes straight to WDM-KS directly from the app), and therefore bypasses all APOs including CAudioLimiter. It is bit-perfect all the way to the hardware driver. This is easy to prove using various methods like...

Assuming Windows audio settings are set to 24-bit output or more (Windows will dither if outputting 16-bit), and assuming you don't have any APOs running, then yes.

Exclusive mode is always bit-perfect as far as Windows is concerned, regardless of how volume control is done. If you are operating with hardware volume control (if it works in exclusive mode then you are), then changing the system volume will not change the bits that are sent to the DAC. The...

Does GLM support what is sometimes called "Sound Field Management" (SFM) with multiple subwoofers, i.e. EQ'ing each subwoofer separately in order to achieve flat response at multiple listening positions at the same time? Basically the equivalent of MSO. If not, can individual subwoofers be EQ'd...

I am worried about the audio latency that would be induced by having a general-purpose computer in the middle of the chain, which is not normally designed for reliable real-time low-latency DSP. That product page is grossly misleading - it mentions "eARC" and "PCM 5.1" which is impossible as...

…but not below 100 Hz (I was wrong earlier - it's 100 Hz, not 125 Hz), which is the limit of measurement. Approved Document E: BS EN ISO 717-1:2013: So, in other words, there are no requirements for subwoofer frequencies, sadly. The walls could be acoustically transparent at 50 Hz and...

That is only true in free field conditions, not in a reverberant room. Especially at low frequencies where rooms tend to be more reflective and speakers tend to be omnidirectional. In practice it'd be more like 3 dB or so.

Careful, building sound isolation standards like these often specify a frequency range that stops short of subwoofer frequencies. For example the regulations for the UK only cover >125 Hz. I've heard that some builders exploit this and design walls whose resonance frequency sits somewhere below...

In my experience, using a subwoofer near-field comes with its own problems: small differences in listener position results in wild variations in bass level, and it can be awkward as the parts of your body closer to the sub "feel" more bass than the parts further away. I've tried it once and...

I think it would be interesting if @amirm measured the DAC performance of the SW42DA, given that as far as I know it's the cheapest way to convert multichannel Dolby/DTS HDMI directly to balanced analog (the only alternative I know of, the Marantz AV10, is 5 times more expensive). I do plan on...

I'm considering using the SW42DA purely for its balanced analog audio outs, ignoring the AES67 output. Does anyone know the easiest way to get XLR/TRS out of these weird-looking analog audio terminal blocks at the back of the SW42DA? According to the specs it's a Phoenix 5-pin terminal block...

For your mental sanity's sake, I would strongly recommend not having anything between the source and the TV if you can avoid it. Especially if you're going to put high demands on that link like 4K120, HDR, VRR, low latency, PC (RGB) etc. It will drive you nuts. You want that link to be as direct...
