1080p is a placebo for most anime, but 1/8th of the shows this season are Full HD, and over half the shows this season are produced above 720p.
FLAC isn't a placebo. There are people who can reliably tell the difference between a lossless source and a lossy encoding, even at high bitrates. I'm one of them (I'm regularly 19 for 20 in ABX testing). If the bitrate is high enough (~256 kb/s), I won't notice the difference unless I'm concentrating on the sound, and it is more noticeable on some soundtracks than others.
That said, Herkz is right about them being placebos for this.
>FLAC isn’t a placebo
I'm using qaac with -V 73 (which is ~144kbps) for all of my music and I can't hear a difference to lossless.
The only difference I see is having ~5MB instead of 30MB or more. :^)
>maybe during the songs at most.
Not even there. With a decent AAC encoder (qaac/FDK AAC) and bitrates between 128kbps and 160kbps it is pretty much impossible to hear a difference.
>maybe during the songs at most.
That is where it is obvious, but scenes with background music, especially classical music, will give it away too.
qaac -V 127 will produce audio I can't differentiate with FLAC on casual listening, and it is what I use to save space.
About 40 GB of my music collection is in 256kbps VBR AAC, but another 40 GB is in ALAC because I can still hear the difference.
It's annoying, I'd like to save that space.
>With a decent AAC encoder (qaac/FDK AAC) and bitrates between 128kbps and 160kbps it is pretty much impossible to hear a difference.
If you mean 128-160kbps per channel, I agree. On most dialogue, 128 kbps will be transparent to source. But with music, anything with complexity, 128 kbps is nowhere near transparent.
For example, by the second episode of Saekano Flat, two seconds after the opening song began, I would know whether I had forgotten to change the audio track from 128 kbps AAC to 224 kbps EAC3 because of the hollowness of the sound (the 128 kbps AAC lacked the reverb of the 224 kbps EAC3).
Most people can't hear the difference. But if you want difficult, let alone impossible, you have to go much higher than 160 kbps.

Just with the difference that
1) Amazon's AAC audio is CBR and not VBR/TVBR and has a 16 kHz cut
3) Probably uses the default ffmpeg AAC encoder (which is worse than qaac or fdk aac)
The difference you hear is probably the low cut (the eac3 audio has a 20 kHz cut) or the way the aac encoder works.
It's not the low cut. It is AAC itself, and how it works that is the issue. AAC can be bad at reproducing percussion faithfully.
I can't hear much above 16 kHz anymore. And I'm noticing it playing it through the speakers on a flat panel TV.
I just grabbed the audio from the opening theme, using the 224 kbps EAC3 as baseline, then re-encoded it as AAC using Apple's AAC encoder.
I did a true VBR (317 kb/s), and a constant bit rate at 128, 192, 256, and 320 kbps.
I could tell the difference in all of them, but only bit rates below 256 kbps were obvious without concentrating on the sound.
The opening is really percussion heavy, and there is a cymbal that starts it off. In the EAC3, there's a brightness to the cymbol as it carries through the opening bars.
In every AAC version below 192 kbps, it cuts off the trailing edge of the cymbol. All the AAC versions lose some of the higher pitched resonance of the cymbal.
You can even hear what the AAC encoder is leaving out. Using Audacity, add an original track and a converted track, then invert the converted track. What will play is the audio that's not in the converted track. (Note: the Apple AAC encoder adds priming frames which have to be removed manually to resync the tracks).
EAC3 is worse than decent AAC. EAC3 is transparent at ~160kbps while AAC is transparent at ~128kbps (both depends on the encoder though).
Also, lossy -> lossy is always a dumb idea. A comparison based on that makes no sense... Ofc AAC sounds worse than EAC3 then.
