Audio Hardware / Re: Headphone fit
Last post by saratoga -
I am looking for a portable version, of the above,  for use on the road; slightly lower sound quality acceptable but not as low as the phones audio out, using the phones internal DAC, when running wired headphones from the phone.

Most mobile phones now have nearly 16 bit limited output into a line in.  You didn't mention listening to a lot of 24 bit audio, so unless you have an exceptionally poor phone, you may not need anything at all.

Why does my install not want to run musical spec even though I have pasted it into both components and the main folder. anyone have any ideas..

The author of playptmod, st3play, and ft2play, kind of pissed me off. And the BASS removal was just coincidence.

Thanks for all that...  You've done a lot of work!

Some people say all amps sound the same, so this goes to show that they don't.
I'm not THAT surprised that there was a difference in phono preamps.    There is a LOT of gain in a phono (or microphone) preamp and high gain means noise can be an issue.     And, with phono preamps, you've got the RIAA curve to deal with, and the input capacitance can vary and cause (slightly) different frequency response with different phono cartridges.

Of course "all amps sound the same" isn't always true, but I'd say it applies more to power amps and "preamps" used as "control-centers" with line-level inputs with little gain or often with attenuation.

Sadly then, here's my result of mp3 320 vs. uncompressed wave, not that I really expected a different result:
Don't be sad! :)   It's not that your hearing is bad, it's that MP3 can be better than you thought.    (And, maybe MP3 would do worse with different, harder-to-compress, program material.)

Automatically saving artist art inside the track directory is not recommended because:

1) Won't work with all music types, e.g. radio streams and YouTube tracks, since there won't be a valid folder location
2) May duplicate artist images in several locations, e.g. if you have more than one album by the same artist

However, you can set the save location to what you like, e.g.
Code: [Select]
Image [Artist] Folder Location=$directory_path(%path%)\%BIO_ARTIST%
Set using right click > menu > sources > server settings > edit biography.ini > save > restart foobar2000. The example, or something similar, may achieve what you asked. But it involves using %path%, which along with other path related functions, is not recommended because of the save incompatibility with radio streams etc. But if you know you never going to play such sources or similar... Choose a folder location that doesn't contain any other images, since all images are loaded from the set folder. Accordingly, to maintain specificity the script won't save to folders where other images pre-exist. The save filenames for the images are automatically generated and cannot be changed.

General Audio / Re: Parametric EQ and Crossfeed for Android?
Last post by lélé -
I gave a try to Neutralizer and I'd like to thank you because it proposes a very interesting approach.

As far as I understood Neutralizer relies on Android EQ.
It seems to work fine with all my streaming applications: very good point!
I just regret it is limited to 12 bands which does not allow 'fine tuning' in the highs, where my (current) IEM frequency response curve is quite 'bumpy' and where my audition suffered more of abuse and time.

I am still looking for a solution for cross feed that can be used with my streaming application by the way...
Any suggestion?

Thank you Arnold. Very interesting.

Are there any modern power amps that you are fond of?

Lots of them.  You later on mention value. Generally the two best ways to get watts for good prices, and the two best ways to do that are would be AVRs and amplifiers for professionsl audio.  AVRs give you a lot of watts per dollar, but their maximum power output for channel might be on the low side. Amps for pro audio like Crowns, QSCs, and the like come in various power ranges that vary from a lot to totally humungeous.   Used within their ratings, they can both sound great.

Bob Carver's Phase Linear amps and TFM series amps are still very highly regarded and sought after on ebay. Good value (power) per dollar. I always respected his 'outside the box' approach in his engineering.

Carver does a lot of things these days that make me suspect of his sales efforts. For example, for years he went around suing speaker companies based on a patent that he had for a subwoofer. The patent was eventually found to be invalid for a number of reasons including the fact that there was prior art, some of which Carver had previously used in his own commercial products. That automatically invalidates the patent, but Carver picked mostly on small companies that would settle rather than go through an expensive court fight. Eventually, he picked on somebody with deep pockets who cleaned his clock in court. It was fraudulent bullying all along.

I have recently renovated my media and computer room. After that, I noticed that my speakers produced very much bass suddenly, which I attributed to their new placement.

Good call. The performance of a speaker is highly dependent on the room it is used in, and its location within that room can be as much or more important.

Quote
I couldn't figure out what exactly caused this

The sound quality of a speaker, especially at low frequencies is strongly influenced by the size of the room, its dimensions, how the surfaces are covered with reflective or absorptive materials, and the distance from the speaker to the various walls and corners.

Quote
I also didn't want to reposition all furniture and put them in their old positions, so I decided to look for cheap and easy ways to reduce bass.

The cheapest and easiest way to control bass is equalization. But, there are natural limitations to this because bass is influenced by the effects I just mentioned which are in 3 dimensions, but an equalizer can only control 1 dimension. So, you might get the bass right in one part of a room, but move around and thebass you hear might get worse.

Quote
I found many threads on coupling-decoupling techniques and decided to try that

Bad call.  Speakers are almost entirely coupled to the room by the sound coming out of the speakers (usually cones) and ports.

Things like pads and spikes are at best 10% solutions and are generally even less influential than that.

Bass is one of those things that is fairly easy to measure, and if you strengthen it or weaken it or make it deeper or shallower, the measurements change.  Ever see an article that shows how bass measurements change with things like spikes and pads?  I never have, and one reason is that there is not a lot of change to report.  Instead most such reports are based on colorful prose and poetry.  

There are strong effects on the human mind some call expectation effects, and others call placebo effects. The alleged benefits are almost always discerned and reported by means that are well quantified, even though changes in bass response are relatively easy to measure.


How about them apples? ;-)

Hi, what's the reason that you dumped playptmod, st3play, ft2play and bass.lib all of a sudden after all these years?

Why are always 4 spikes used instead of 3?
I dunno... Why does a chair have 4-legs?    Probably for stability...  It's easier to tip-over with 3-feet/legs.

...I'd always assumed those spikes were for carpet...

Quote
What can I say? The difference is unbelievable (for a sub-20€ mod, that is) - much cleaner bass response and less rumbling.
Please re-read TOS #8 and be careful about making such claims here.     I don't doubt that moving your speakers made a difference, but I'm skeptical about what problem was solved with the spikes.   But, what I think  doesn't matter...   The moderators are very strict about the rules and it greatly reduces the nonsense you get on "audiophile" sites.   You can talk about spikes, or moving your speakers, etc., but if you are going to make claims about sound quality you have to do the blind listening tests.
