Please be aware that much of the software linked to or mentioned on this forum is niche and therefore infrequently downloaded. Lots of anti-virus scanners and so-called malware detectors like to flag infrequently downloaded software as bad until it is either downloaded enough times, or its developer actually bothers with getting each individual release allow listed by every single AV vendor. You can do many people a great favor when encountering such a "problem" example by submitting them to your AV vendor for examination. For almost everything on this forum, it is a false positive.

Yes, reassigning both and leaving a gap from other drive letters might be better (though the important thing is that they don't clash). You can delete metadata_cache.fpl from the root of both drives at the same time to wipe the component's own metadata cache as that uses relative paths (or running 'Rewrite database' again afterwards should have a similar effect).
Thanks, I'll that a try!
General Audio / Re: fix outcentered audio track

I must say that your answer is too complex for my present level of comprehension.

What I hear from this old speech, is that it's not loud enough.
Normally, what I would do is to normalize the track, or amplify portions by portions the track.
But in this case, I can't because it's overclipping.

Googling I found
it explains from 01:30
the question is how you fix this, without changing the sound, make it more symetrical without affecting the sound?
and indeed speaks about "phase rotation" solution.
but presently don't know what to put in, because I neither understand the "phase rotation" effect, nor what's the solution, the goal/target.

Use a plugin such as Audication Phase AP1 (free) and try different values around 90° and see how they affect the peaks. In Izotope RX there are modes (suggest and adaptive) that can determine the amount needed to minimize peak level. You could gain 1 or 2 dB of headroom, but there will probably be peaks reaching both positive and negative limits. I do not know what kind of filters are available in your software. All-pass filters in an equalizer could also be used. These all will subtly affect the sound.

This waveform is not "wrong". It's a characteristic of the sound source. In broadcast radio a phase shift is sometimes used on voice to maximize loudness.
General Audio / Re: fix outcentered audio track - asymmetric waveform

>It is likely an asymmetrical waveform, which is naturally produced by some brass and bowed instruments, and human voice.
It's pure human voice, not the single instrument

I presume sthg went wrong with the voice recording

Asymmetric, that's the word I think. If one looks at the track, the "zero of the wave" is put to "high"

>You could rotate the phase to center it.
What does it mean??

It is likely an asymmetrical waveform, which is naturally produced by some brass and bowed instruments, and human voice. Ocasionally happens with synthesizer patches too. You could rotate the phase to center it. There are tools in Reaper, Izotope RX channel operations and Stereo Tool for that. But you will need to squish it with a limiter afterwards as there will be some high peaks left over.

It could also be a low frequency vibration. I can't tell from the zoomed out screenshot. But unlikely. You can attenuate that with a highpass filter.
Support - (fb2k) / Re: ID3v2.3 multi-value compatibility
Last post by SimBun -
Upon further digging I've found that from a local media point of view, the Sonos app is really best avoided:
  • Patchy tag/codec support e.g. No display of album artwork on ID3v2.4; No seeking on Ogg Vorbis (and hit or miss with album artwork too)
  • No multi-value support on any format, it seems to take the first one it encounters
  • Need to share music using smb v1 (or a running Windows/Mac PC)
  • It merges albums with the same names unless you first filter by album artist, even though it separates them in the album view e.g. Greatest Hits
There are probably many more!

The one good thing they have going for them is that they're a UPnP compatiable renderer, which means I can use a much more feature-rich UPnP server/control point; it just means my girlfriend will have to use Spotify/Sonos for online music and BubbleUPnP for local music.

Anyway, thanks for all the help and the pointer to the '/' being part of the official v2.3 spec.
General Audio / fix outcentered audio track
Last post by livebe -
I didn't know how to title the question, as never experienced such a case.

I have a sound track see attached picture, which:
1/ obviously the first 2min have been added to the rest, so it is easy to split the audio in 2 files.
2/ the audio after 2min seems off balanced, non centered, in wave display.
As such it prevents from normalizing the track, see attached pic.
What can I do to correct that?

Other Lossy Codecs / Re: exhale - Open Source xHE-AAC encoder
Last post by andrew.46 -
There is one Linux player that already has native support, or at least two. Rhythmbox, assuming your copy of GStreamer was built with libfdkaac support. Or Gnome's generically named music player, I forget its name.

And now you have jogged my old memory I remember that FFpaly will also play these files back by specifying libfdk_aac as the audio codec on the command line...
