I have two completely separate viewpoints on this, one from a sound design aspect and one from a listening aspect.
Pros record at 24/96, so if you're doing music/sound production you might want to go with that.   (Of course, most music is distributed on CD or MP3/AAC.    24/96 is overkill for almost everything (maybe absolutely everything), but pros also often record at -12 to -18dB, so they are loosing a few bits of theoretical resolution, no matter what the bit-depth.

...   = 144dB which is roughly the range of human hearing from what I remember.
That's really not relevant to musical dynamic range...   If someone shoots a gun next to your ear, your ears start ringing and it may be a few minutes before you can hear a whisper.   You loose some of that theoretical range after hearing loud sounds, and music with that kind of dynamic would be totally unpleasant.   

...and I think by around -110 dB, there's hardly anything at all to be heard.
I suggested an experiment to someone recently, and you might find it enlightening too...   Load a song into Audacity* (or your favorite audio editor).  Somewhere around the 30-second mark, drop the volume by -90dB for a few seconds, then bring the volume to back to normal.     (-90dB is near the lower-limit for 16-bits.)   Play back and listen as loud as you like, but "no fair" boosting the volume during -90dB part.    I suspect you'll be surprised how far-down -90dB is.    Then you might also want to try something more "realistic" like -60 or -70dB.

The other thing I've been thinking about lately is, the whole analog vs digital debate.
There's no "debate" among people rational/scientific people.   Does anyone debate that analog VHS is better than DVD or Blu-Ray?  The situation is similar in audio and video, and digital "wins" in every way.**   (Except with "audiophiles" who enjoy the "warm" crackle and distortion from vinyl records.) 

you can pitch those recordings down by an octave or more and the sounds won't audibly degrade in quality because inaudible frequencies, if they exist, are being transposed into the audible range.
There nothing intentional in the ultrasonic range.   Any ultrasonic artifacts may "enhance" or degrade the sound if pitch-shifted down into the audible range.   Or more likely, they are attenuated to the point where they are totally masked, except possibly for any high-frequency noise that's present when there is no signal.   And, any pitch-shifting THAT extreme is going to sound completely unnatural anyway.

* In Audacity, use the Amplify effect to attenuate the level, and since the maximum attenuation in Audacity is -50dB, you'll have to do it in two steps if you want to go to -90.

** I'm speaking of at-least CD quality or high-quality MP3, etc.   Of course we can have "telephone quality" digital audio that's worse than some analog formats.

Hi, great script! There's a way to automatically save artist art inside the track directory? With %artist%.* name? Like album art... or the foo_uie_biography...
Fine. They're always in memory in foo_osd. I have no idea what those "biggest software vendors in the world" are doing, as I haven't written their software.
All presets are always "loaded", you are only choosing to display and modify one of them.
In memory. 
Not going by two of the biggest software developers in the world, it's not. That's the point of the combo box auto-loading like the concrete examples I've shown. Not how you think it should behave by just displaying it to edit it. 
It behaviour should be to automatically load the selected preset to then have the option to either execute it, edit it, delete it or saveas/save over it in any of those combinations. 
Why would you edit first, select the preset and then save when the logical way would be, select the preset first, make your changes, click save or new to make a copy. Just like most software does it. Or click new and use the previous preset as an example to create a new one. 
I'd love to see any other software which shows FB2Ks behaviour. I've yet to come across any.
Please enlighten me.

Right, so now you have your counter examples. Great. Now wait for Peter to do something about it. Or not.
Scientific Discussion / Hybrid IEM
Last post by lélé -

There is an increasing number of 'hybrid' IEM, which utilize a dynamic driver for bass and Balanced Armatures (BA) for mids and highs.
Such 'hybrid' IEM are praised by audiophile websites.

As for me, I gave a try to Oriveti New Primacy 'hybrid' IEM and I was quite impressed with the bass.
I tried to match the bass with BA IEM and EQ, with no success.

But we all know that impression can be very misleading, so here come the questions:
  • Apart from pure placebo effect, is there any chance that a dynamic driver would offer different bass presentation? (I was wondering if temporal aspects (ex. : decay) could explain such difference...)
  • Is there any real world advantage to combine a dynamic driver to BA? (Leading to more complex design, with crossover and so on...)

Many thanks for your feedback!

Sorry, I'm still a noob, could you please suggest a code line to try?

I have a pair of Westone UM Pro 30, I do like them, so far happy with the standard foam but previously had silicone custom molds done for my UM-2s and they were excellent....but I lost one, doh!! I'll get another pair when I can afford it. Don't go for vinyl, it's hard and it hurts your ears after a while.

You're referring to custom ear-tips while I am hesitating between Universal IEM and Custom IEM, the latter having a completely custom shell (including the concha).
I don't know how comfort issues with 'vinyl' (acrylic?) ear-tips that your recommandation may suggest translate (or not) with 'fully custom IEM'.

Maybe Etymotic ( )
They isolate pretty good, at least good enough for me to listen to chamber music on the train and occasional plane.
Comfort, let say I got used to them :)


I used to have Etymotic ER-6i many, many, years ago.

ER-6i were supposed to be ER-6 with an higher sensitivity and a slight bass boost (just like ER-4PT for ER-4S).
While ER-6 themselves were supposed to be a cheaper alternative to ER-4S, with the same target frequency response (diffuse field target). I guess Etymotic was using the same 'trick' as for ER-4S for ER-6 (adding a resistor to the cable to 'tune' the frequency response and use the BA underdamped).

As far as I remember, ER-6i lacked bass and sounded 'bright' (and fatiguing!) with my music player. I also had some 'background hiss'. Cable noise was horrible (until I had something to block the cable in the chin). However:
  • Memory is a dangerous thing!
  • I could not find ER-6i impedance curve, but I suspect impedance to be very frequency-dependent. Combined with my player output impedance and small linking capacitor, this may have affected frequency response.
  • I like a bass boost when listening to music with IEMs (compared to listening with speakers) and at that moment my music player did not offer a decent EQ, nor it could not be 'rockboxed.'
Nowadays, these issues could be corrected easily today by using a simple resistor network (for impedance related issues and 'background hiss') and proper EQ (or going for the XR variant).

Nevertheless, I not convinced by Etymotic approach regarding comfort.
Sometimes I use my IEMs in the bed and since I am lying on the side Ety's are not suitable at all.
Plus it seems that they still have a very noisy cable (to be clear) I'm referring to mechanical noise) that will need to be replaced.

So not my first choice.

If track numbers are tagged 1, 2, 3, [...], as opposed to 01, 02, 03, [...], there can be a problem once track 10 is encountered, depending on whether the tags and/or files are sorted as numbers or as text. If text, Track 10 will usually play after Track 1, with tracks 2 though 9 following for a ten-track album.

Your tagging/file naming can be correct to the eye, yet still fail if the software reading it doesn't sort as you expect.
