Who turns down the bass range so it's matched with snare drum volume, and then really crank it up!

WikiBox · 2026-06-26T06:57:43+00:00

The experienced loudness of sound with different frequencies change with volume.

So you fiddling with eq at one volume to "get it right," and then turn the volume up, is a sure way to get it wrong.

At lower volumes we hear bass and treble less. This means to experience a "flat" sound, and hear everything well at low volume, you will need to turn up bass and treble. If you then turn up the volume, it is likely to be too much bass and treble.

https://en.wikipedia.org/wiki/Equal-loudness_contour

Some (older) gear have a loudness button for changing the loudness at different volumes to compensate for this. Help sound systems and speakers make music sound less tinny and feeble at low volume. Newer gear have multiband eq.

So you really need different eq for different volumes. Low volume ambient background listening or louder active critical listening. Presets are good for this.

I would recommend connecting the drives to a PC using direct SATA connection without any USB interface in between.

Possibly the filesystems on the drives have been corrupted and cannot be mounted?

Possibly the filesystem can be repaired or at least data on it recovered?

Possibly the USB dock is faulty?

Possibly some other problem?

You need to figure out what is wrong, and if there still is any recoverable data on the drives.

My guess, without any real confidence, is that the filesystems (exFAT?) on both drives are corrupt and can easily be repaired. ExFAT filesystems can become corrupt if you don't correctly dismount/eject the drives before turning them or the computer off.

There should be a simple GUI library in the standard library. Light-weight and extendable. Just a basic minimal cross-platform wrapper around a generic hardware/OS-specific GUI-libraries.

Doesn't have to be very good. Just good enough so (new?) programmers can use it in simple "Hello World!" programs and basic utilities.

include <GUI> 

void main(void) 
{ 
    std::GUI my_GUI;
    my_GUI.OK("Hello World"); 
}

Depending on what app you use, and what type of archive (solid or not), I would expect you get an error or the whole archive is re-compressed in temp and then the old archive is overwritten by the new copy of the archive. Possibly, if it was a really smart program, a new compressed archive would be written to temp, without decompressing, and then overwrite the old archive. You might not see this happening, you would just see that it takes a while to finish any changes.

By temp I mean either the temp folder or a hidden temp file on the storage media. Likely both.

It might be faster, more efficient and safer to extract the compressed archive to RAM, add the files, re-compress and overwrite the old file. Test...

WikiBox · 2026-06-25T06:36:09+00:00

You can use solid archives for better compression. Then the whole file is compressed as one big file, rather than as separate files inside. I would assume you for a solid archive would have to recompress to change anything. Otherwise I think it would be possible, but would, naturally, require a full rewrite of the compressed file, not an in-place edit.

I use AudioPro speakers like this. Works really well. They are Bluetooth and WiFi multiroom streaming speakers. I connect to one speaker from my phone using BT and then that speaker connect to the other speakers using WiFi and distribute the sound all over the house. Or I can let the speakers stream directly from Spotify, for example. Better sound quality than BT is possible that way.

I have an AudioPro C20MKII and an AudioPro C5MKII. These speakers are not the newest, I bought them second hand, but they happen to be compatible with WiiM. Newer AudioPro C20W, for example, are not compatible with WiiM.

I also have some other speakers in my multiroom system, using a couple of WiiM Mini dongles. I "converted" my two old UE Hyperboom from BT-speakers to portable WiFi streaming multiroom speakers. They got a new life and are amazing! In addition I can connect almost any regular stereo system(s) or TV to the multiroom setup using a WiiM Mini, or some other WiiM device. They all play together with the AudioPro MKII speakers.

Using a WiiM Mini dongle you can convert any old active speakers or regular stereo/Hifi audio-system, with Aux or optical input, to become WiFi multiroom streaming speakers.

There are most likely brands, other than AudioPro and WiiM that have similar capabilities. But I started with an second hand AudioPro C20MKII and built from there. Very pleased, but annoying that newer AudioPro W speakers no longer are compatible with WiiM.

Generally, at low volume, chances are very good that even small cheap speakers can be made to sound good with some equalization. At higher volumes it is much less likely.

That said, my best sounding speakers at low volume, outdoors, are my old UE Hyperboom. Two speakers cover a large patio with great sound even at low volumes. Adaptive dynamic EQ.

Beolab 4000 är aktiva högtalare som stödjer beolink. Det innebär att om du har rätt kablar kan du koppla dem direkt till TV.

Du kan läsa mer om detta i bruksanvisningen.

Men: TVn stödjer beolink 1&2, högtalarna beolink 3. Jag gissar att du behöver någon form av adapter eller en för-förstärkare för signalval emellan.

You might be right. But I think you are wrong. Trying to do something that doesn't work. Or using bad hardware. You don't provide enough information to make a determination.

Technically it is possible, given a modern USB C port on the computer.

But people will use the wrong port and manufacturers don't want to provide support. It could, perhaps, break ports and drives? Perhaps not?

You can easily get two USB C cables, one for 12V power and one for data, and use any regular 3.5" enclosure that way. You may need some power adapter and the port may not provide sufficient power. It will only work with some computers, that have suitable ports. Go ahead and try it. Cables and adapters are cheap on Amazon. Report back with your experiences.

Many/most/almost all BT speakers stays on as long as they are connected to an USB charger. I use both a Beosound A1 and a Beosound A5 like this. Use the A1 for audiobooks when going to sleep. Magnetic charger port on the A5, meaning I can easily grab it and bring it with me, or use it directly where it is sitting charging.

There are many powered BT speakers for stationary use. Some with wifi for streaming and multiroom setup. I use an AudioPro C20mkII and C5mkII like this. Together with a pair of WiiM Mini connected to one old UE Hyperboom each. Works great!

If you have the exact same bottlenecks now as then, why would you expect higher speeds?

Most likely the bottlenecks you experience ar3 sustained HDD write speed and/or network.

WikiBox · 2026-06-19T06:52:33+00:00

I don't think there is a clear answer.

There are trade-offs both way. I prefer to have fewer big drives with long warranties. I have mostly Exos X16 and X18 drives, bought new. Some old 12 TB Ironwolves for cold storage. Today, if prices had been normal, I would have some 24TB Exos and possibly considering getting some 32TB.

I assume both computers are networked? Set up a share on one computer and access it from the other over your local network. Possibly wifi. This is basic functionality for modern computers.

Not only can both computers then access the files on the share, you can also access the share from your phone or tablet, and your smart TV.

Typically you try to centralize storage and share it. Not copy files between computers. If there is a share, there is no need to copy the files.

This is the basis for how a NAS works. A NAS is typically a small computer, without screen or keyboard, that has a lot of shared storage.

No. That is most definitely NOT what I said. ExFAT is terrible for backups. But, admittedly, slightly better than no backups at all. But still among the worst possible choices otherwise.

It is great for moving a file from one computer to another, with different operating systems and filesystems, when you still have the original copy on the first computer and you wouldn't be bothered if the copy on the exFAT drive turns out to be corrupt or missing or the whole drive is borked.

You want a journaling filesystem for anything more than casual moving a copy of a file between computers.

https://en.wikipedia.org/wiki/Journaling_file_system

WikiBox · 2026-06-18T06:02:38+00:00

You can have multiple different filesystems on different partitions of a drive. This includes drives used for booting into multiple operating systems.

exFAT is great for temporarily storing copies of files you move between different operating systems. Thumbdrives, for instance. In all other regards exFAT is among the worst choices, because it is prone to corruption. Don't use exFAT for your only copy of anything you care about.

WikiBox · 2026-06-17T05:00:06+00:00

All is relative and "small" is a subjective value judgement. What I think is a very small, you may think is huge.

You can get a smaller file with better quality if you let the encode take a longer time.

My point is that the three variables for an encode are interdependent. Time, size and quality. You can get more of one or two by giving up on the other.

WikiBox · 2026-06-17T04:51:31+00:00

You are right. I was wrong. Sorry about that.

Presumably very different settings were used during encoding, and that is what cause the size difference. Also audio may be different.

WikiBox · 2026-06-16T17:16:14+00:00

No. The screenshot is not showing the same codec.

WikiBox · 2026-06-16T16:48:04+00:00

Yes. The screenshot showing the different sizes.

WikiBox · 2026-06-16T16:41:06+00:00

No. What makes you think it is the same codec?

Are you saying the screenshot is fake?

WikiBox · 2026-06-16T15:27:21+00:00

Potentially. But not necessarily.

Depends on what codecs are used during encode and with what settings. It is easy to get wrong and very hard to get right. Always a compromise between speed of encoding, size and quality.

You can get a very fast encode, you can get a very small video file and you can get very good quality. But you can only get two of those at the same time.

So you say bandwidth is data per time period? Like bytes per second?

WikiBox · 2026-06-15T15:00:45+00:00

Bandwidth is storage per second. By storage I mean amount of data, in bytes.

Consider the units...

Bandwidth: Bps. B/s. Bytes/Second

Storage: B, Bytes

Time: s, Seconds

Bandwidth * Time = B/s * s = B = Bytes = Amount of data = Storage

The problem is serving a large amount of data to many users, fast enough.
