Ogg Vorbis - Tech / Re: Vorbis 1.3.7 aoTuV and Lancer patches
Last post by Kraeved -
There is something wrong about Lancer mod 2021-05-11 hosted on RareWares.
It is unable to correctly encode WAV when its sampling rate is less or equal to 11025 Hz:
SSE2 version outputs silence, SSE3 outputs heavily distorted sound.
All other Vorbis encoders (original, Aotuv, Venc aka Aotuv 2021-03-20, FFMPEG's libvorbis) do the job as expected

P.S. Also, Lancer mod section on the website is missing its own anchor, <a name="oggenc-aotuv"> is used instead.

Code: [Select]
$ oggenc2 in.wav -q 1 out.ogg

46 825 = out.original.generic.ogg
51 187 = out.original.x64.ogg
51 301 = out.ffmpeg7.x64.ogg
51 301 = out.ffmpeg7.x86.ogg
52 409 = out.aotuv.generic.ogg
55 291 = out.lancer.sse3.ogg
56 562 = out.aotuv.x64.ogg
56 655 = out.lancer.sse2.ogg
56 670 = out.venc.x64.ogg
56 674 = out.venc.x86.ogg

Ok, now the problem is clear. There is no row having he value "composers (67)" in BadFieldTable. With the following query and batch it should work:

Query:
Code: [Select]
SELECT
  Node1
FROM BadFieldTable
ORDER BY Node1, album, discnumber, tracknumber COLLATE NaturalNoCase

Batch:
Code: [Select]
DROP TABLE IF EXISTS BadFieldTable;
CREATE TABLE BadFieldTable AS
WITH BadFields AS (
  SELECT
     composers,
     composersort,
     composersortorder,
     conductor,
     album,
     discnumber,
     tracknumber,
     path,
     subsong
 FROM MediaLibrary
 WHERE coalesce(composers, composersort, composersortorder, conductor) IS NOT NULL
)
SELECT
  fieldname || ' (' || count(fieldname) OVER(PARTITION BY fieldname) || ')' Node1,
  *
FROM (
  SELECT
    'composers' fieldname,
    *
  FROM BadFields
  WHERE composers IS NOT NULL
  UNION ALL
  SELECT
    'composersort',
    *
  FROM BadFields
  WHERE composersort IS NOT NULL
  UNION ALL
  SELECT 'composersortorder',
    *
  FROM BadFields
  WHERE composersortorder IS NOT NULL
  UNION ALL
  SELECT 'conductor',
    *
  FROM BadFields
  WHERE conductor IS NOT NULL
);

No, but as there are no real tags then you need to define the provided information as TFExpression columns in foo_sqlite.

Feature request for Peakmeter part (and to the extent, spectrum/spectrogram visualization): A feature to display Mid/Side representations of all stereo/surround pairs like this

This can be useful for letting me know if the particular song have phase-related/mono-compatibility issues, even though foobar2000 is not a DAW obviously

General Audio / Re: Test files needed

I have most of the "test" CDs after about 1990,  including the Stereophile's, Chesky, both Sheffield/XLO,  etc.
I don't have CD-CHECK (tm).
But, honestly, most of the ones that came out after ~1988 are worthless for techs.
For example, that Philips Audio Signals Disc 1 – SBC 429 , has a whopping 99 tracks. This and other Philips test CDs were put out by one of the formats' developers. It comes right out of the R&D dept. Not sure Sony put out their own suite other than YEDS (which is on Archive). Denon may have, as one you noted above:

http://www.technofileonline.com/texts/testcd89.html

One critical, must-have track, as was often reported on in Measurements section of reviews,  of Stereo Review, Audio and even Stereophile (for a while), was/is/remains the SQUARE WAVE test.
It's importance (in audio) is controversial, to say the least. But it is very weird and interesting how folks go out of their way to discredit it -- especially when it comes to is application in digital audio:

In my filter I have low frequencies displayed in high resolution just fine,  it have nothing to do with links you provided above.
Do you mean showcwt or something else? And as I said before, you can't have precise time resolution while having higher resolution on lower frequencies at the same time

Irrelevant, showcwt have high resolution of low frequencies.

Yeah, saw the Pierre Varney on eBay, It is not that uncommon on eBay or the used mkt for high $.
The Philips disc is the one I really want as it is all signals, dedicated to CDP diagnostics.
Audio Signals Disc 1 – SBC 429

Also, having an original stamped version of any test signal CD -- as opposed to burned CD-R -- is often preferable by techs as the purported signal level and integrity (visible on amplitude of eye pattern) are higher and more stable/accurate.

I have created a new component...

Is it possible to add the old, good RMS meter (according to IEC 61606:1997 / AES17-1998 standard - so called RMS+3) on the upper bar next to Peak and TruePeak readout?
It would be great to have an option to display ONLY the upper bar and hide all the graphs.
Yeah, but I would like to see Peak/RMS bars as in foo_vis_spectrum_analyzer new peakmeter mode that display all channel levels, expand the already existing bar visualization to show all momentary, short-term, and integrated LUFS bars and also add the Mid/Side representations (which I think it could be useful to let me know there are phase issues that make these mixes not mono compatible)

Of course, displaying graphs should be optional as you said and new bars visualization should able to co-exist with the amplitude vs. time graph like the old Peakmeter Spectrum component
