Re: [slim] Logitech - please work with Pandora for 192kbps streaming!

2010-02-10 Thread Fleury

Rather than wait for Pandora or Logitech to blink, try this work around
- Use the Pandora One desktop applet (a very nice impovement over Open
Pandora). Because it's coming off your PC and not SqueezeCenter your
Pandora stream should be 192. Pipe it to the SB via your wave input
entry in "Favorites", using the WaveInput plugin (a pain to configure,
but worth the effort):

http://wiki.slimdevices.com/index.php/WaveInput_plugin

This should take the Pandora stream right off your sound card, with
whatever quality level you have set for wav in your SC/SB Settings -
enjoy.

Actually, what I want, as a paid subscriber, is the ability to use
their "Music DNS" with my own music, the way I use MusicIP.
I realize that this could be a big development job for them - but then
they have a product that produces income without having to pay licensing
fees - and there'd be less bandwidth required so it might pay for
itself.
It'd also be something they could provide into all markets, even when
they hadn't yet negotiated licensing agreements so they could start
marketing pre licensing.

I'm guessing that track identification is where the bulk of the work
would be. I -think- there are already some music fingerprinting
algorithms out there - but they could start out just assuming tag info
is correct and go from there. Maybe they could work a deal with
MusicBrainz or the current owner of MusicIP.

Once they had something like this, I'd hope to also be able to say "I'm
looking for new music like this track/artist/album - don't play anything
already in my library".
And I'd love to be able to switch between a MusicIP mix and a Pandora
mix.

Sometimes ignorance is bliss :-).  It's for this reason that I've never
done serious ABX testing.

On my home setup, I used 190 kbs VBR LAME files initially.  When I
upgraded it to FLAC, I noticed a subtle yet very real difference with my
headphones.  The music sounded fuller with more presence.  

On my iPod, I use LAME mp3 files.  I use this mostly in my car.  Yes, I
could train my ear to hear the difference in my car, but I don't want to
:-).  Given the noisy environment of a car, it would be difficult to
train my ear there anyway.

I agree with your second statement, that indeed would affect revenues. 
However trying to sort their international side might provide
significantly greater opportunities.  i believe licensing is now
slightly better.

On a more positive note looks like AndyG has been on Twitter with their

Happier customers. A higher guarantee of renewed subscriptions.
Offering a better, more consistent service (what else are they going to
do, offer FLAC streams but only to browser based clients?). :-)

I think it compelling enough: customers ask for it, plus more music
with very good quality (which 192 represents, 128 is a tad bland for
good jazz and classical recordings) to more clients... sounds like a
common sense bet for them.

Please get off the pedestal.  I know all about hydrogen audio and have
been using the LAME encoder and the Fraunhofer encoder before that. 
I've been encoding my music for over twelve years and have participated
in numerous ABX tests that demonstrate that I usually can pick the
higher quality sample.

It also might interest you to know that while I don't purport to be an
audiophile, I used to sell extremely high end stereo gear.  Listening to
some top of the line Martin Logan speakers powered by Krell amps and
high end DACs will go a ways towards getting you comfortable with what
is possible in audio and you can set your expectations from that.

2009-11-22 Thread pablolie

For the sake of the OP, let me say that I fully agree and would love to
get the 192k version of Pandora on my multiple SB equipment.

On the subject of increased quality, any well recorded jazz or
classical album will truly allow one to hear the difference between 128k
MP3 and the original. The difference between 256k/320k and the original
will be much harder to detect unless you are very familiar with the
original and know your MP3 artifacts (typically a hissy nature in the
highs, sometimes even pre-echo and similar), but it can be detected.
But, again, it takes a good recording and familiarity with it. 

>From listening to Pandora 128k and 192k streams, I can attest to the
fact the 192k stream seems less tiring. Mind you, the 128k channel
sounds great for an Internet radio channel - but if we can get more, why
not? It is in the nature of the digital consumer to demand a lot for
free, and the impossible if we pay a subscription - add that to the
cluetrain manifesto. :-D

Re: [slim] Logitech - please work with Pandora for 192kbps streaming!

2009-11-22 Thread toby10

As has been suggested, how well the file has been encoded matters as
much as the bitrate.  I hear many 128k stations that do not sound as
good as some 96k stations, and I'm guessing the encoding method is
likely the main difference.  As a general rule (and as I do) searching
for the higher bitrate streams will usually render better overall SQ,
but it is not true 100% of the time, unfortunately.:)

Oh No ! It sounds like we are in complete agreement...Oh
wait.this isn't the audiophile section so it's OK if we agree
:-)

For me it becomes very difficult to hear diffs at 256VBR which is what
I use for my Itouch.
My 160GB Ipod classic has all lossless but with 160gb it's no prob.

agree on all your points (in particular the "ear training"...with some

I have done quite a few blind tests that I have distinguished between
128 and 192 or higher listening to well recorded classical and jazz.
Most commercial pop recordings are so bad that it doesn't seem to make
much diff.

It takes an experienced listener with a well trained ear to hear the
difference.

At 128 the soundstage is flatter, less 3 dimensional. There is less
hall ambience which is so helpful in creating spacial cues. There is
less air around instruments etc.

192VBR seems to be the starting point for adequate hi-fi. It is much
harder to hear differences above that rate, although I have been able to
do that on some recordings.

At 128 it is actually very easy to hear the diffs blind on well
recorded music especially if you are very familiar with the recording.

One should remember that any listening test is testing the listeners
"ear training" as well as the bit rate.
Not everyone will hear the diffs. However the majority of people can be
trained to hear those diffs, as proven through years of musicians
improving their aural skills in ear training classes.

Agree! And this affects the average listener (who could care less as
long as they can download the song and it plays on their nano) as well
as the "audiophile" that pays $3,000 for a single 3 foot audio cable
because it adds more "air" to the music.

Of course they might. Imagine a consumer who knows nothing about sound
quality and is listening on $5 computer speakers. If they are thinking
of signing up for a music service and they have a choice of one service
that advertises the number 192 whereas another one uses the number 128,
which one do you think they are most likely to choose ?

It doesn't matter if they don't know anything about bitrates or the

I agree with you that for the 'average joe' who thinks that an AM radio
sounds "great" there is no need to go higher than 128kbps.

However

It doesn't take amazing hearing to be able to tell the difference
between 128 CBR MP3 and VBR MP3 that are both LAME encoded.  All it
takes is some musical knowledge and decent equipment.

Most of the listening test I've seen that show that users can't pick
apart 128kbps vs 192kbps mp3 are usually performed using $5 computer
speakers.  Color me shocked on those numbers.

You might be mixing things up here and imply that 128 AAC (which is
pretty much superior to LAME at the same bitrate) is "good enough" for
most users.

All I can tell you is that to me it's pretty evident which I am
listening to, at least with the Pandora service (and who knows how the
music is encoded).  They obviously offer the 192 kbps streaming for
their paying customers for some reason, I doubt they would spend the
money on placebo affect.

Agreed.  I thought the Squeezebox guys and the Pandora guys were tight,

There's plenty of discussion of this on the web by very informed folks
(in this forum and other places), so I don't want to turn this thread
into a repeat of all that info. You may have amazing hearing, but there
is lots of scientific evidence that clearly indicates that it is fairly
rare for any individual to be able to ABX in a blind test the difference
between a properly encoded 128 mp3 with the original CD. If you were
posting over at Hydrogenaudio.org the folks would demand that you post
your blind ABX test results to back up your statement about detecting
differences (one of their terms of service). Of course, we're not over
there and things are much looser here. 

I can't speak to streams from pandora as there are so many more
variables in the mix other than just the actual source file (and not
sure how to easily do an ABX test with pandora stream since you don't
have the source file in another format).  Keep in mind that even
extremely small differences in volume can make one source sound better
than another (again, lots of hard evidence on this).

Bottom line, Pandora may very well not sound as good as your local
files, but in general, 128 (created with a modern, quality encoder) is
typically transparent for most users on most music. Your statement that
the reverse is true flies in the face of lots of controlled experiments.
I'm not trying to pick a fight by the way, I just hate to see myths
about lossy encoding quality be perpetuated. That said, there are lots
of reason to rip music to FLAC (or other lossless format), and I do so
with all my own CDs.

I have consistently been able to pick up on the differences between
even my --alt preset extreme LAME rips and the original CDs.

I have a modest sound system  in my workout room that consists of an
old (but very robust) Yamaha AVR and a pair of Polk budget speakers.

Numerous times when listening to Pandora (and busting my butt) I've
noticed how flat, lifeless, distorted and dull the audio is.  I will
frequently then play this same track, from the same Squeezebox from my
own library and the difference is extremely noticeable.

In fact I would say that it would be hard for someone NOT to be able to
tell the difference.

Not to put too fine a point on it, but 128kbs is not exactly lo-quality
garbage compared with 192. There is lots of evidence that most normal
human beings can't ABX mp3 128 compared back to original CD in a blind
test (visit hydrogenaudio forums for lots of info). That said, I'd love
192 simply because if it exists, I want it (same reason I listen to all
my own files in lossless FLACbut it is not because I think I can
actually HEAR the difference between lossless FLAC and mp3--because I
can'tin fact, I can't ABX lame mp3 at -V5 from original source on
high-end equipment or good headphones except for a few known, rare
samples.)

It's only going to come at the insistence of higher ups at Logitech. 
Not from one developer emailing another and asking "Dude, where's the
new API?" and getting a response, "Dude, I'm swamped."  My guess would
be that the revenue being generated for Pandora from owners of Logitech
products is pretty small, so 192k support is a pretty low priority.

Thanks Andy.

Maybe if more people complained to Pandora we could get this sooner
rather than later.

The ball is in Pandora's court, we're waiting for an updated API.

[slim] Logitech - please work with Pandora for 192kbps streaming!

2009-11-19 Thread jmpage2

I am a paying Pandora One account holder, which means that when I'm
listening to Pandora on my computer I am treated to 192kbps audio that
sounds notably better than 128kbps garbage.

Unfortunately this enhanced audio quality does not work on the
Squeezebox platform.

I contacted Pandora support about this and they said that they have
considered adding 192kbps audio streams to other devices but that it
would also take work on the part of the device maker to support this as
well.

So, if Logitech has any pull with Pandora whatsoever please try to get
us 192kbps audio for the Squeeze products.  I have three players and am
considering a fourth but since Pandora is what I use most it's a real
drag to listen to low quality garbage on my mid-fi and hi-fi setups.
