BitPerfect (was: Audirvana Alternatives) - Page 38

post #556 of 774

Happy new customer here. Great app, just what I was looking for.

 

So far so good except having trouble with using my Flac files (w/ Fluke), but have not had too much time to really sort it out. May find alternative to using Fluke or just keep using Audirvana for my limited Flac library. However for my main library which is all Itunes compatible compressed high bit-rate files I am enjoying the bump in sound quality.

 

One question.... how many users are using BitPerfect on the go with just the onboard sound card and what improvements if any are there? I think I can hear a difference (definitely hear a dif. at home w/ better quality gear.) just plugged into the headphone out of my MBP. My only concern is when I'm in homework mode at the library or traveling and multi-tasking that I'm using unnecessary resources. Well, not really a concern but more just curiosity what the developer and other users think.

 

Thanks,

Dogwan

Then, at the end of "Track 5" you'll hear a little of "Track 3" before BitPerfect realizes iTunes' lie and starts on "Track 6".

 

There are some potential workarounds for this, check out the "fixedindexing" section of the manual.



Is the section?

 

iTunes Response Speed


Controls how often BitPerfect checks iTunes' status.  This determines how quickly or slowly BitPerfect responds to changes like pausing a track or dragging the volume control slider. Faster response speed increases CPU use, and may have an adverse affect on sound quality.

This option is disabled when "Minimize iTunes Interaction" is enabled.

Recommendation: The default setting of 1-tick left from "Fast".
Troubleshooting: 
If you are experiencing problems with tracks repeating certain parts in a loop, move this option towards "Slow".

Nope, that refers to a different problem, if you hear music repeating the same part in a loop. "Fixedindexing" is near the bottom of the manual.

Thanks for your BitPerfect agentism

 

I didn't have any issues with the betas that I couldn't work out.

 

There's a couple of new glitches with v1. I have some stutters from up sampling and some looping from iTunes interaction.

 

I'm sure they're specific to my combination of new Mac Mini, Lion, Arcam rDAC, USB. I'll try to sort them out one setting at a time

Found it, but it appears I would have to add it to all my library. Look forward to receiving the information on the undocumented option! Thanks.

A bug fix release, 1.0.1, has been released. It addresses two issues:

 

- Fix a problem with BitPerfect choosing the wrong bit depth or sample rate with certain DACs.
- Fix a problem with bit depth limiting on certain DACs.

post #562 of 774

I managed to sort out my issues with 1.0 by turning off '2x up-sampling to maximum'

Just did the 1.01 update. Will test further...

post #563 of 774

I'm not able to download the 1.01 update.  (Not a big deal, 1.0 is working fine; just thought I'd like to keep up with the latest version).  

 

When I go to the App Store, it shows all my apps updated; when that's happened in the past, I've been able to download the update to another mac on my network, and then install/update it on the correct mac.  

 

But now it just says "installed" on the mac it's on, and gives me the option to purchase it again on any other mac.  No update is shown to be available.

 

Any workarounds for this?  As I said, it's not critical.

Unfortunately that is out of my control. In general, making a backup then deleting the app often helps. Also try logging out and back into the Mac App Store.

post #565 of 774

Move the app out of your Applications folder, restart the App Store. See what happens.

Tim--

 

Version 1.0.1. fixed the inability to play 24 bits on my MacBook Pro. Now, however, I can't get iTunes to output 16 bits. Regardless of how I set the preferences, Bitperfect says 24/41.1. The sound, however, is magnificent. In head to head comparisons, Bitperect totally outshines Amarra 2.2, especially in vividness and tonal color. Congrats and thanks.

At the moment, BitPerfect will pad the bit depth, the idea being that any DSP effects may benefit from the extra bits. I'm thinking about how to add a "strictly bit perfect" option in a future version that would disable this behaviour.

I see you mention DSP effects.  Any plans to add VST/AU support?

Yep, I'm also looking at crossfeed algorithms. I'm hoping to do AU support for the next major version, I'm not sure about VST.

Awesome.  AU support would really be all I need but I know others would like VST support.  Crossfeed sounds interesting as well.

 

By the way, I was quite impressed with the overall improvement with v1.
