General A/V / Re: High resolution audio - lowest audio setup?
Last post by magicgoose -
Being able to really distinguish 16bit an 24bits music it only happened to me two times in a blind comparison, more correctly with only two songs of classical music that where direct recordings and also where specially dynamic and I'm not sure if it was due to the bit depth differences or the conversion... both song where level matched and in one I sensed if like the 24 bit version had more punch and in the other a near silent pasage in the 24bit version was totally silent in the 16bit version, and in the one that had more punch I guess the bit depth correctly because I knew that it was a direct recording.

But any other time that 16bit and 24bit sounded different was due to the audio path and the DAC, because in this situation while the 16bit and 24bit sound different a 16bit to 24bit converted file sound identical to the native 24bit audio version.
Your comparison was either not blind, or totally incorrect.
Bit depth conversion can't alter the amount of punch[es] at all, even in theory, even if done in worst possible way.
I'd suggest testing 24 bit record against itself converted to 16 bits. Not against some other record which could be made from something else entirely — that would make the test incorrect.

The ability to hear pure tones does not tramslate to being able to hear those frequencies in music.  Blame that pesky masking.

FWIW, 34 was chosen so that there would still be plenty of margin for filtering.
For some music/genres, there could be very loud tones in that area.
Off the top of my head, very loud HF tones (perhaps above 16kHz but I don't remember exactly) can be heard in "Perdition City" album by Ulver. (a musically good album by the way if you ask me).
I guess some other extreme/experimental/electronic music could have something like that too sometimes.
Sure, in most of the regular music the content above 16kHz would be extremely hard to hear if at all possible, but music is a broad term and it seems that signals with whatever characteristics may comprise music nowadays.

General - (fb2k) / Looking for resampling feature
Last post by xerces8 -
Hi!

I want to play a 96ksps file, but my hardware supports only .... well it does not support 96k. I guess it supports 44,1 and 48.

So I need a (live) resampler.
Is there such a thing already by default in foobar2k?
Or must I install a plugin/component?

Note my output plugin is foo_out_upnp (output streamed to a DLNA DMR/DMP).

Versions:
Windows 8.1 64 bit
foobar2k 1.3.17
foo_out_upnp 1.0 beta 18

Ogg Vorbis - General / Vorbis Comments and Sort Order
Last post by cliveb -
Is there any "official" Vorbis comment that can be used to control the order that albums are presented?

For example, consider the two Beatles albums "Rubber Soul" and "Revolver". The Vorbis comment ALBUM will cause them to be presented in the wrong chronological order. In my Squeezebox system, the LMS server accepts another comment "ALBUMSORT", and I can set these as, say, "1965 Rubber Soul" and "1966 Revolver", which results in them being displayed in the correct order.

But I've noticed that other Vorbis players (eg. the radio in my car) don't seem to take any notice of this (presumably non-standard) ALBUMSORT comment.

So is there some other Vorbis comment that all players are expected to recognise that would do the  same trick?

Audio Hardware / Re: Searching for a tube amp / compressor
Last post by Atmasphere -
A tube amp isn't going to make it more dynamic.

However, if you use a single-ended triode amp that does not use feedback, they can sound 'dynamic' on account of the distortion they make.  But such an amplifier will be challenged to drive the speakers you have in mind, especially with your budget.

Pioneer made an expander unit back in the 1970s. You might look for one of those- they turn up on ebay on occasion.

General Audio / Re: Source for objective headphone review
Last post by 16Bit Audiophile -
Measurements:

If you want a very objective approach, Inner Fidelity has great raw headphone measurements (IEM not so much). But it demands a very good understanding of how to read them because his current compensation is bollocks. Also his axes are very clinched which makes reading the peaks very difficult sometimes. Headphone.com is the old website for which Tyll Hertens worked for. I think he did a good job catching up on Inner Fidelity.

Rtings has some good raw measurements, but do keep in mind that they use a different measurement setup (head and coupler) so the raw frequencies might deviate from Tyll and thus would need a different compensation. I also don't agree with their target if you want studio linearity but they are currently working on a refined target curve. Again, be very careful when trying to read the frequency response because I know people discussing headphones for 10 years who still misinterpret them.

IMO, GoldenEars is not too useful. Their curves are heavily smoothed and their selection of head- and earphones is quite different to what is available on the European market. YMMV.

If you want subjective opinion and prefer to read articles, more often than not I would agree with Tyll from Inner Fidelity. I do think he prefers warm sounding headphones (ironically his compensation shows the opposite) but overall I think he is without bias.
I write a tiny fraction of articles on Headfonics but Marcus is the main guy. His tuning description is usually spot on and I personally rarely disagree.
