I voted Opus 160 because I've ABXed some problem tracks and came to that value. I also like Vorbis at -q 6, which targets 192kbps. I try not to use MP3 because I can just barely make out artifact on "clapton_44k" sample from this listening test, at LAME -V0. The first guitar note has a buzz (a chain of short attacks) that gets smeared by mp3.

All of that being said, the artifacts are "noticeable, but not annoying" at bitrates much lower than that, even for mp3.

I can't believe people refuse to put up with imperceptible artifacts from Apple AAC/256, when in comparison, dust on vinyl makes such a loud racket.

My archive library is in flac for peace of mind reasons, but I'm happy to listen to transparent lossy codecs.

I wish more audio people would adopt subjective ratings like lossy encodings: 5 for indistinguishable, 4 for distinguishable but not annoying, 3 for distinguishable and slightly annoying, and so forth.

For me, CD has always been 5. Vinyl is between 3 and 4 (obviously). Since between CD and HiRes is a 5, I have no use for HiRes.

Hi,

The poll aims to collect data on which file format and bitrate combination is preferred by most individuals (or sounds acoustically transparent to them when compared to lossless).
Ain't Flac already a lossless format?
Anyway I choose others because this survey doesn't have 192kb MP3.
 
Are you sure that the 1TB disk was a rotating hard disk and not a SSD?
Well of course, the technology has changed, but the price per Mb... this is my experience:
ca. 2006 1tb exrernal hdd: 110eur still working!
2021 1tb external ssd: 120eur
And still 2021 1tb external hdd: around 60eur
Not much of a change in 15 years for computer related electronics

speed, weight, availability and size has changed.

15 years ago a relatively slow 32MB CF memory card costed way more than a 32 GB micro SD
The computing power of a 15 year old PC is less than your average phone a.t.m.
 
ALAC (FLAC)

You didn't add 160kbps AAC which I mainly use, With Lame MP3/FHG AAC to cover edge cases.

Sorry, wanted to say "for being computer related electronics". What i mean is that one expects anything related to computers decreases price per given metric or increases metric for a given price at least one order of magnitude in such a time frame, in your example even 3 orders of magnitude. Hence my surprise when i needed to buy a new external drive... prices were basically the same! Yeah, smaller, more silent, but for my use case, same result.
In any case 1 tb of rock and roll is a lot of rock and roll even in FLAC, so why not
 
WAV 16/44.1 just so I could tell myself it's the same as CD. I could have used 320 kbs and it would have sounded fine.
 
Is Apple still being hairshirted about FLAC support on iOS etc ? If not then to my mind 16/44.1 across all streaming services in a FLAC container should be the norm.

For ripping or purchasing for local file storage, same.

For anything at a greater bit depth or sample rate, just use the most efficient FLAC compression but as an optional streaming layer.

If bandwidth/ data costs are a concern for some, aac/mp3 above 256 as a lower tier setting.
 
FLAC - although that is for consistency these days. I used to be able to tell the difference, before my hearing started to drop off, between MP3 320 and FLAC, but I don't how much of that was down to the psychoacoustic modelling that is built into MP3 and the additional processing overhead.

I just saw a Western Digital external HD for $39.99 at Best Buy. Storage is dirt cheap nowadays.
 
I voted FLAC as all my ripped files are FLAC and I buy FLAC downloads. Given that memory is cheap I figure why not. But I would be perfectly happy with 320k MP3, I'm playing a psycho-acoustic trick on myself.

This is because both prices are for disks far out of the main stream. If you look at disks using the same technology then the models with the smallest and the largest storage size share similar bad price/byte relations - caused by low production numbers I'd say. Look at disks with medium storage size (let's say half of the biggest ones) and then compare generations and you'll see that price/byte drops significantly. Beware though that short fluctations of the market price can be very high!

In March 2021 I bought an external 18 TB disk (Western Digital 18TB Elements Desktop with a single 18TB hard disk) for €379. This is much cheaper in price/byte than the 1 TB disk. It was acually cheaper than buying a OEM disk without external housing - don't know how they can do this ...

Actually, i was quite surprised when i recently found out that 1TB HDD costs today still the same than in 2010.
Seagate Cheetah ST3300007LW (SCSI@320Mbps w/10K.7rpm) @300GB was around $400 in 2009. Heck, a single SCSI cable from the AdaptecController (@$300+) to a single HDD was $99 on a good find. Of course, if you had a SCSI chain as a part of your computer, you had a have a bunches of HDDs strung together bcuz the capacity just was not there for the $$ but the performance was unbeatable, the 15k rpm versions were passed the 'knee-of-the-curve (re: Performance/$$).
 
For myself, i keep it as wav as in uncompressed. I dont see the need to compress it since we have ample storage space (1TB HDD can store over 1000 CDs). for redundancy, i use a 2 HDD NAS in RAID 1.

But fortunately as my salary is a bit better than in 2010, i use flac (why not?)

This is because the manufacturing cost of HDDs have hit bottom. A 2TB drive barely cost more than 1TB to manufacture (mostly is just an additional head).

Yeah!! Before SSDs, 15k rpm scsi were the fastest drives and they cost a bomb!! Still remember those Megaraid controllers using Intel chips.
