How can I make it so that all groups have equal separation between all of them?

Attempt 1 - minimum row height: $add(%el_item_count%,6). Singles displays fine, but album separation is too big. https://i.imgur.com/PGLyoPB.png
Attempt 2 - minimum row height: $add(%el_item_count%,2). Album separation is fine, but singles get cut. https://i.imgur.com/NDildMO.png

I know it must be some simple math but I'm really bad at it.

Opus / Re: Opus 1.3-beta is here

To me 128 Kbps opus is Transparent for 5.1 tracks and 64 Kbps is transparent for 2.0 tracks

Opus is certainly doing a great job at these bitrates, but not universally transparent at such low bitrates IMO. It depends a lot on the content. I attached an example that should certainly be ABX-able at 64 kbps and show very obvious differences at even lower bitrates, just in case you want to find out what sort of artifacts to listen for.

At what bitrate would you consider Opus universally transparent?

I went for 160 kbps on my whole library for that reason, didn't want to have to encode twice.

Difficult question. It's "easy" to prove that something is not transparent with a given sample using ABX, but it may be impossible to say "at this bitrate things will always be transparent, for any sample, for every ear".

Having said that, at 160 kbps I'd feel pretty confident that quality should be "universally really good", with no nastyness to be expected. If you find a real-life example that exhibits audible artifacting at 160 kbps, I'd guess jmvalin may be interested to investigate.

Sounds to me like you have a short forming somewhere between the output and ground, which disconnects at times. If you have a multimeter that can do this - and all of them should I think -  set it to short circuit detection and check for that.

Im very new to electronics and I built this guitar amp circuit on a breadboard:



and it was working really nicely. Now Ive decided to put the circuit on a universal pcb which i'll use in the actual amp. I soldered all the components on but no sound comes out when i play. Because of the different layout of the universal pcb the circuit's grounds are connected differently than they were on the breadboard, so maybe thats the potential problem, since its the only difference i think there is. Sadly I dont remember what it looked like on the breadboard and I didnt take any pics. Heres the layout of the circuit on the universal pcb:



Heres something I dont understand, when I measure the potential between the output and the ground with a voltmeter, it corresponds nicely to the signal from the guitar, it seems like it should work. But when I measure the potential between the wires going into the speaker (which are connected to the output and the ground) i get zero volts between them always. Why is that and how can it be fixed?

Also sometimes when I poke around with the voltmeter at different spots on the ground and output it will randomly start working and sound will come out. I cant really notice any pattern when doing so though.

Heres the pin layout for the LM386 operational amplifier:



And this is LM386 datasheet: http://www.kynix.com/uploadfiles/pdf2286/LM386M-1.pdf

Once again Im very new so Im sure Im making a ton of embarrassing mistakes and that my soldering is terrible lol

Denon D7000, by far. Not only are they detailed and reveal differences between, say 320 kbps MP3 and FLAC, quite easily, they are extremely musical and pleasing to the ear. When used with proper equipment (not a phone or integrated sound card), the sound is big, warm, engaging and cohesive. I use them with a Abrahamsen DAC and Vincent hybrid vacuum tube amplifier.

For listening on the go, I use Sennheiser Momentum 2. For this purpose, they are excellent phones, as they can be driven quite easily by an iPhone and the sound is still full and cohesive.

I also have Sennheiser HD650 and Beyerdynamic DT770 (80 ohm). They sound muddy and closed in comparison. As for Sennheiser HD800, they are extremely detailed and have a huge sound stage, but they sound thin, analytical and less engaging to my ears. To get any bass at all you have to play ridiculous high volume levels. They do not play music the way it's meant to be heard. They are however very useful as a tool to reveal differences in formats and bitrates.

You'll never be able to do it in raw javascript which is what JScript/WSHPanel uses. There might be a method without powershell, but I don't know what it is.

Ever since Sony introduced their Street Style/behind-the-neck headphones (I think this was 2000), I've only used those. They're cheap (MDR‑G45LP around $15), light and you can wear them with a bicycle helmet. I just wish the cord was on the right side. I cannot speak for quality because that's all I've used.

Seems like a similar bug. Same optimizer in a newer form in VS2017 after all. In a typical Mozilla fashion their solution seemed to be to fuck everyone who doesn't have a new machine and just require SSE. Peter's solution is to compile the problematic code with /d2SSAOptimizer- parameters to get working code until MS releases a fixed version.

HD800 for home, AKG K7XX at work.  Various IEMs for mobile but CustomArts CIEM mostly.
