post #106 of 746

As for the icon status - green for ON and red for OFF would be nice.

post #107 of 746
How about color for Active and b/w as it is right now for inactive?
post #108 of 746

Red for off would confuse me, as AstoundSound is red for on. How about red for on and grayed-out for off?

New version (0.21) available here.

 

Changes include:

  • Prep for app store (copyrights and such... nothing interesting)
  • Make SoundCheck function smarter (don't rely on file extensions)
  • Add option to configure iTunes polling frequency
  • Device Info for all devices
  • Add very experimental support for non-trivial DACs
  • Fix track position update in iTunes
  • Fix pause does not resume, it stops and seeks
  • Fix track position in iTunes wrong after switching buffer
  • Fix brief blip of sound from iTunes
  • Fix volume slider enabled but no effect
  • Fix crash after disabling/enabling BetterSound when switching track
  • Fix intermittent issue where BetterSound keeps playing the same part of the file in a loop
  • Fix intermittent issue where BetterSound hiccups when user performs "Get Info" in iTunes

 

Most of the changes are for mostly rare bugs, but there are also some very significant changes. The most important being the addition of very experimental support for certain DACs. The experimental device support is mainly for levi4312 and other users whose DACs were not listed in the device drop down. This change should not effect people for whom BetterSound was working before, but just in case, test the new version at low volume! smily_headphones1.gif

 

There is also a new preferences tab where all the iTunes related configuration has been put. A new option controls how quickly BetterSound will pick up changes from iTunes. Drag the slider towards "Slow" if you've been experiencing "blips" in the sound from BetterSound while interacting with iTunes, or if iTunes generally seems to be slow when BetterSound is running.

 

Let me know what you think!

Again, thank you so much!  Still working for me  (Hegel HD2)  ;)

 

Quick question:  are you using Core Audio for upsampling?  Or some other software (SRC)?  And do you think there is any benefit to it?  I'm thinking just stick with the native bitrate, but some folks really swear by upsampling - what's your opinion?

 

post #111 of 746

My tentative conclusion is that today's release fixed the weird problem I was having with BetterSound not properly playing the last 3rd of the track. It was either jumping back to the beginning of the current track (though the iTunes display would still look right) or it would jump to the beginning of the next track (though the itunes window wouldn't reflect this either. Hasn't done it to me yet since the switch to today's version.

 

Thanks!

I'm using Core Audio for upsampling. At some point in the future I'm planning to add a better upsampler, Core Audio (from OSX 10.5 and 10.6, it is possible that they changed it in 10.7, but I don't know) is decent, but not the best.

 

As for whether there is a benefit, that is a thorny question. IMHO this is entirely dependent on the quality of the upsampling done in your DAC. Almost all DACs will upsample the signal you send to them, even if you send at the maximum sample rate they support. Upsampling algorithms built into a DAC are working under more constraints than in software, so my guess is that they are generally not as good as the best software algorithms. Upsampling algorithms do a better job upsampling by powers of 2 (2x, 4x, 8x, etc...) than by arbitrary ratios like 44.1 to 96. So, if it is possible to do the "hard" 44.1 -> 96 style upsampling in the computer and have the DAC do only 2x/4x upsampling that is probably a good idea. But it isn't straightforward to do that, so my thoughts boil down to "fiddle with the options and choose what you like most".

Sorry, guys, but I'm going to have to veto colors. The standard practice is black for in-use, outline or grayed for disabled and color only for alerts. I should have time to get something to you tomorrow, Agentism. As I said, I still want to tweak the application icon a bit as well.

 

On that front I'm definitely open to some community feedback.

I like the app icon... it reminds me of the midrange unit on the B+W 802d, some really excellent speakers smily_headphones1.gif, but I'm open to some tweaking, as you can see from the Preferences screen, Doug's UI sense is vastly better than mine!

post #115 of 746

Here's a behavior I only notice on some tracks:  BetterSound trims the last several seconds of each track.  This is only noticeable when the track does not have "white" space at the end (i.e., as most tracks have several seconds of silence at the end, so most of the time you don't notice it).  But it can be very jarring on a live album (where the first track loses the last 5-6 seconds of the track and the second track starts immediately) or on tracks where the music runs right up to the end of the track (where you simply lose the end of the track).

 

Any ideas on how to fix this?

Yeah, I'd like to know how to do that.  My iTunes doesn't have a stop button.  How do I get it to "Stop"?  confused.gif

In BetterSound, the menu options has "Stop" which will accomplish this.  Not sure how you'd stop it in iTunes itself.

The "stop" option is BetterSound is a good way of doing this. You can also pause a track in iTunes and then switch to the next or previous track in your playlist, that will cause iTunes to go into stopped mode. It seems iTunes is quite silly when it comes to differentiating between stopped and paused.

Hmm, sounds like this would also screw up gapless albums. This certainly used work, I'll track down the problem and fix it for the next build.

Cool - let me know if I can help test - I can easily find examples in my collection  ;)
