Listening Tests / Re: A Session In The Abyss: xHE-AAC vs OPUS at 12, 24 and 32 kbps (voice & music)
Last post by guruboolez -
FhG xHE-AAC did 3.41 on 32kbps? That's amazing!
3.41 but on merged results. For music samples score is "only" 3.21 (voice is easier to handle).
As xHE-AAC 32 kbps was the very best encoder of a group of six I would say that the score is *maybe* slightly overestimated. In different testing condition (eg a listening test with 32 - 64 - 96 kbps competitors) I expect a lower score. Same if I put xHE-AAC 32 kbps as low anchor in a 128 kbps test.

But if I spend one hour at home at home on listening music at 32 kbps xHE-AAC I can give a rough estimation of the score at ~3.0 (which literally means "slightly annoying" on the ABC/HR scale). It's listenable with audible but limited annoyance.
Again, also, it's a matter of taste and tolerance.

No, I have not reported my issue anywhere officially yet.
I send crash report every time.

^ I believe this is what Peter is referring to - you sent crash reports to the tracker.

Try SRC or SOX resampler...

Does optical cable properly support 192000Hz? - could that be related to crashes? (Not sure, just asking)

Correct. To retain intra-album track differences, use ALBUM RG.   But when scanning all your albums to add RG tags, I suggest you go ahead and add both TRACK and ALBUM RG tags.  It's just tags and not used unless you tell your player to use it.  And there may be sometime down the road when you want to make some playlists from different albums and then when playing you would want the player to use TRACK RG tag value.  You can use foobar2000 to add these tags, by album, in a batch manner. A couple of mouse clicks and let it run to analyze and add RG tags to 1000s of albums.

p.s. In my own case, all my players support some sort of "Smart" ReplayGain tag use.  That is, if I am playing songs from the same album, Album GAIN is used.  But if I'm playing a mixture of songs from different albums, TRACK GAIN is used.  This is all automatic.  In foobar2000 this is called "by playback order".  In LMS it is called "Smart Gain".

Excellent work!
This is very interesting test to see the ultimate performance in this extremely low bitrate range. Fraunhofer xHE AAC is definitely very impressive.
From storage affordability point, I personally can't see the reason to go this low in 2021. for local music listening, even for Netflix or other streaming video service it cannot bring too much size reduction because video bitrate is still high.
However, performance and results are still very interesting to see on such low bitrate.

I presume 'Ryzen 7 3700X' foo_dsp_std+12CD0h crashes on the tracker are yours.

No, I have not reported my issue anywhere officially yet. However, I also have Ryzen R7 3700X and my sampling rate is also set to 192000Hz.

Unfortunately nobody else has similar crashes; everybody runs the same code, so it might be somehow tied to your machine.

Well I have and that other person with R7 3700X & 192000Hz who raised it on the tracker seems to be experiencing the same issue. Perhaps a very rare bug?

Edit: I've found the crash log: https://pastebin.com/NQnGwCCy

Judging from the dates on crash files in my profile, crashing started in February this year. That is also when I changed my DAC from NwAvGuy ODAC that I had for 5 years, to Topping DX3 (connected via optical cable). I've had had R7 3700X since its release date and haven't had this issue before.

Technically speaking, it's SSRC resampler implicitly used to upsample audio, to 192000Hz as requested by your audio device.
Unfortunately nobody else has similar crashes; everybody runs the same code, so it might be somehow tied to your machine.

I recommend putting another resampler (anything else than SSRC) at the end of your DSP chain, configured to output sample rate of 192000Hz, this will suppress the code that crashes for you.

Thanks for your help and advice @garym  and @Apesbrain

It does seem I was looking at this the wrong way round. It is not that my SACD rips are quieter, (@garym indicates the example is near the RG target), rather that the CD rips are louder (loudness wars era?).

I have now written tags to the rip I made 8 years ago from the CD layer of the exact same media disc shown in my original post. It used to play back much louder that the recent SACD layer rip. Now that I have added RG tags they both play back at the same level. Below is a screenshot of the CD layer RG values.

I will over time add RG tags to my whole library starting with a subset of folders to check I am getting what I expect. I do want to preserve any relative changes in level from track to track within an album which may be present for artistic reasons. So I assume I need "Album gain" scanning to achieve this.
