CD Hardware/Software / Re: Decode ogg with XLD
Last post by sxxin -
Reviving this old discussion since the situation remains the same as of August 2017..

This would be a very useful feature since I'm transcoding ogg -> mp3 for my car and phone every now and then and I haven't found a proper tool for it. XLD would be excellent, since it's already the best tool for transcoding wav/flac to ogg/mp3. Any other recommendations for mac?

General Audio / Re: Diagnosing Preamp Turn-on Thump

I would guess it's just a design weakness, not a failure, so there's probably nothing to "diagnose" or "repair".

General Audio / Diagnosing Preamp Turn-on Thump
Last post by Bronco Leonard -
My system has a noticeable turn on thump and I have always powered things up (and down) manually and in order.  I now want to be able to power everything up at once and so I examined my system component by component.  I found that the preamp is causing the turn on and off thump.  (Without the preamp, there is a very small thump that I can live with.)  The culprit is my Sumo Athena preamp, which sounds great and seems to be working well except for this problem.  So, I would like some help in diagnosing and repairing  this problem.  Can anyone direct me to posts or articles on this subject?

BTW, I don't have schematics for this piece.  Apparently, Sumo never released them and they are very hard to come by.

General Audio / Re: Powering Up Audio System
Last post by Bronco Leonard -
OP here.  To reiterate my original questions, I want to be able to start up my entire system with one switch, but I was afraid of the large current inrush.  (Each power amp alone causes the lights on the same circuit to blink momentarily).  To get around these problems, I took a well made industrial (metal, not plastic) eight slot power strip and installed an inrush current limiter inside.  Coupled with the ones already in the power amps, this works well: I can now power up everything without any current load problems, and I don't need to buy a power sequencer to do it.

The second issue was the turn on thump, which was one of the reasons I always powered things up manually and in order.  I examined my system component by component and found that the preamp is causing the turn on and off thump (as I mentioned earlier, there is a very small thump without it, and I can live with that).  The culprit is my Sumo Athena preamp and it seems to be working well except for this problem.  So, my remaining question is about how to diagnose and repair this problem.  I am going to start a separate thread for that question.  Thanks for the help and advice so far.

BTW, my system consists of:

Harmon Kardon  HD7600 II CD player
Sumo Athena preamp
Adcom GFA555 II mains power amplifier
Mirage M-3 speakers
Sumo Delilah active crossover
Leach DBA monoblock subwoofer power amplifier
JBL B380 subwoofer (aka Sumo Sampson)

Like I said, mid-fi at best, but I like how it sounds.  The Leach base amp does indeed use a very heavy duty "naively" designed linear power supply that uses isolation - not step down - transformers to power the two rails.  The filter caps are massive.  This simple design gives me a very loose power supply that is more than capable of driving that little 15 inch woofer driver.  The low end is plentiful and very, very tight.  As a result of biamping, the GFA555II also has more power than I could ever use to drive the Mirages.

Thank you guys so much! This line worked perfectly for me:

Code: [Select]
$if($stricmp($left(%path%,1),C),Laptop Music,External Music)|%<artist>%|%album%|[[%discnumber%.]%tracknumber%. ][%track artist% - ]%title%

Now, what do I need to add to make it ignore articles in the list (e.g. list The Beatles under B instead of T)?
I read about using $stripprefix, but I'm not sure where to insert it to make it work.

Thanks for the update @knik

I didn't assume my claims on the sound difference were the center point here, but while I do appreciate that sentiment, I must say that was a little intimidating to read regarding my initial post.

I have not produced any listening tests and this happened a few weeks back already, so I did not have the objective of conducting anything like that. However, I don't really see much sense in doing that.

You seem to have vastly underestimated how much myth and legend backs up spikes and isolation pads. I've investigated them  in detail and for the most part they are expensive placeboes at any price.

Any individual person could simply alter the sound files to prove their point.

The technology behind the ability of equalization to address problems like these is so solid and widely accepeted that the point is pre-approved today.

OTOH I can't see how one could gather much relevant evidence without out comparing a system with spikes and pads to one that lacked them or used a different configuration of them.

Quote
What I wrote about was definitely subjective experience and I am not a spike-salesperson, so there's no reason for me to trick anybody into saving a little money and energy when trying to test this setup themselves. However, the placebo-effect may definitely be a viable explanation.

I'm not worried about you tricking me or my friends. I'm worried about you tricking yourself which seems to be already accomplished.

Anyhow, maybe I haven't described the problem and the outcome detailed enough:

So, I was moving the furniture in this room, including my computer and the speakers. After everything was located at its new destination and I listened to music, I started to notice a stronger bass than I was used to. I have had this setup and the same speakers for a couple of years now, so that is definitely something that you can pick up right away. Nothing else had changed, not the height of the speakers, the distance from the back wall, the angle towards myself, just the location within the same room. (Before: in a corner, now: in the middle of a flat wall.) I wasn't aware that the placement in a room could have such a huge impact on the sound, so I started looking for solutions in different directions.

As the saying goes: Been There, Done That, many times, have the T-shirt, named my first son after it...  ;-)

What you have described is how audio works, and frankly I'm surprised that you're surprized.

Quote
The cheapest and easiest way to control bass is equalization.

That's kind of true,

Wrong. It is absolutely true in almost every case. Again, I'm surprised that you're surprised.

Quote
however I have not used any software equalizer before

It is very clear that you are very unfamiliar with the concepts of equalization and frequency response. Frequency response is a very strong influence, detectable in what may seem like vanishing amounts, and often overbearing before the numbers describing it become impressive.

Quote
and I don't have a hardware equalizer anywhere in my chain

Read my lips: You don't need a hardware equalizer in almost every case because software equalization is already so pervasive. If you are following this forum you must have noticed that there have been multiple posts describing how equalization is simply a standard part of most popular computer operating systems.   There have been specific mentions of Linux, Android and Windows, and that covers billions of computers - most of the computers that exist and are running today.

Quote
(and haven't felt the need for one previously), so it wasn't either going to be cheap or easy for me to find, install and test global software EQs or buy a hardware EQ + cables.

The points of resistance are most mental and typically based on fear. Download a file. Install the software. Run the software. Less than a minute and a handful of keystrokes. You are now the owner and operator of an equalizer.

Quote
Additionally, the annoying bass sound was not present in all frequencies across the board. They were rather multiple specific bass frequencies that would produce that irritating rumbling sound, figuratively swallowing other frequencies that I haven't experienced before like that.

Read my lips: Removing or reducing musical sounds at just the frequencies they have become annoying is what equalizers do.

General Audio / Re: Parametric EQ and Crossfeed for Android?
Last post by Arnold B. Krueger -
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.

Equalizing every bump and null, and/or within a fraction of a dB does not necessarily contribute significantly to listening pleasure.

Our ability to even detect a frequency response discontinuity goes down as it gets narrower. 

Freedom from detection is a far more sensitive to what is required for the perception of natural balance, or listening pleasure.


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

Fix the tracks.  Many audio editors have channel mixing features. Ideally, you'd access the .wav versions, add a little cross feed, and then re-apply any compression that you might have chosen.

IME there are not a large number of tracks that don't have any crossfeed at all or are objectionable because they have way too much separation.  For example, there are all those old Beetles tracks that are essentially two channel mono, with all of the instruments and voices slammed to one channel extreme to the exclusion of the other.  Those represent a short term phase, and for a variety of reasons including mono compatibility and compatibility with cheap LP players, that phase mostly went away pretty quickly.

Some recordings with extreme channel assignment and mixing or un-mixing are still made, but it seems like they were intentional, and part of the artistic experience of listening to them.

3rd Party Plugins - (fb2k) / Re: R128Norm
Last post by kode54 -
I don't even see how that would work. Maybe it would be more constructive to ask the author of VB-Audio Voicemeeter Banana to add such a thing to their software.

Tracks are not being played in the proper order, so in that sense sorting is the issue. I put forth a possibility and the reason for it.
