@ Der Internet

Just out of interest, how many tracks in your library?  Approx.

Also @ Daeron

I haven't been keeping up to date with foobar2000 changes recently. Are you aware of any issues running Yirkha's foo_dynfill component on the latest releases?  Slower or faster (any issues?).

Thanks,
C.

Does Izotope’s RX 7 Declip use FFT?
I do not believe so. The author has described the method as "bidirectional least-squares autoregressive" interpolation. Stereo Tool employs a type of fourier transform omitting clipped samples, compensates for lost level, and then performs an inverse. There is significant spread of pre/post-echo from the linear phase filter around each repaired interval, but in RX only samples above the threshold are changed. But the restoration quality in Stereo Tool is better overall.

Noise reduction and other manipulations in the frequency domain can often do more harm than good if there is too frequent interpolation happening or the noise/distortion is of comparable level with the signal. Plastic warbling.

Scientific Discussion / Re: SELA v2 - A lossless audio codec with focus on simplicity and code quality

Interesting project! Kind of the same goal as my project SLAC, except that SLAC is just pure C.

I also had trouble running your new version because of its dependencies, but I was able to run your previous version (0.1.2-alpha). Surprisingly the compression ratio was almost identical to SLAC on the 1-hour corpus file I use for comparison testing.

Unfortunately, in about 3 places the restoration was not bit-exact over several samples. Hopefully that's been fixed in your new version, which I'll definitely try once there's a version without dependencies.

Hi David, I have switched to MSVC and created a new release. Can you check now? I was aware of the issue you mentioned. That was one of the motivations for the rewrite. 
Okay, the new MSVC works for me now. Tried a 1-minute and a 5-minute file and they decoded bit-perfect, except that a tiny portion was missing from the end in both cases.

However, when I tried my 1-hour plus file the program gobbled up all available memory and most of the CPU and I could barely regain control of the system! Not sure what's going on there, but it prevented me from verifying the data (it had generated no output once I was finally able to kill it). I'm on Windows 7.

Another thing I noticed is that it crashes if the input file doesn't exist.  :)

3rd Party Plugins - (fb2k) / Re: External Tags
Last post by iridescentaudio -
Hi, I'm having some trouble with external tags not working correctly with a select few mp3s. (using External Tags version 1.5.9 - I only noticed this today, it may have been an issue for much longer.)
The mp3s in question all come from the same source. Here's just one short jingle uploaded as an example:

https://www.dropbox.com/s/fgnbhj95d9jt851/125_2_run_home_run_%28in_game%29.mp3?dl=0

What I am experiencing: if I generate an external tag for this or other related mp3s, upon playback the tag information disappears from foobar2000's playlist - as if the external tag isn't being read. On pressing stop, the tag information repopulates.

Things I have tried, but have not helped:
- Reducing the internal tags to only contain ID3v2
- Optimising the file layouts
- Fixing VBR MP3 headers
- Rebuilding MP3 streams
- Verifying integrity (all files concerned are reported as 'OK')

One thing I know will work is if I use foobar2000 to transcode to fresh mp3 files and bin the originals, though obviously not keen on doing that if there is another option. Any ideas/suggestions?
