I wouldn't worry too much about it...  I've never heard any difference when converting in either direction between 48kHz (for video) and 44.1kHz (for CD), no matter what resampling software I happen to be using.

...And I ONLY resample when I need 48kHz for video, or 44.1kHz for CD.  If I'm making audio files (MP3s, etc.) from video I leave them at 48kHz.  

I've seen graphs that show a difference, but I'm pretty sure any competent DSP programmer can write a resampler that's better than human hearing, as long as you are not downsampling down to the point where you loose high (audio/audible) frequencies.

WavPack / Re: How about multi-threaded wvunpack?

FFmpeg's wavpack decoder is multithreaded and is much faster than wvunpack even with 1 thread.

I just tested wavpack 5.1.0 and ffmpeg 3.3.1 and ffmpeg was noticeably slower in single-thread mode.

Hi, is there a reason not to use multiple threads in wvunpack to speed up the unpacking of lossless WavPack files to WAV? If not, could you make a multi-threaded unpacker?

I think most common programs already do this.  Foobar, dbpoweramp, etc.

Too few people use Wavpack to encode 10MHz data, I suppose...  ;)

720p H264 + AAC video has itag 22. It used to have 192kbps in the past. But in the spring of 2016, they began to use 128kbps AAC for it
New videos (2017) use 192kbps AAC on itag 22.

Hi all,

I don't know if I'm searching on the wrong places...

I have some 48kHz FLACs in my collection, but for compatibility reasons I want to convert them to 44,1kHz - I am thinking about making this conversion final and not keep the original 48kHz since I don't think I would hear any difference.

Still, I would like to know which resampler is theoretically the one with the best performance in foobar:

There is dbPoweramp/SSRC, and there is PPHS which can be selected in the converter setup. PPHS has an ultra mode, I guess this is something like "better accuracy while sacrificing encoding speed". Is that true?

I just want to get the most accurate result possible, I don't care about encoding speed since I don't use the resampler for live listening but only for a one time conversion of my few 48k files.

Which one would you recommend here?

While searching through the web, I can't find anything helpful that encourages my decision. Any tips from the community?

Thanks in advance.

In Acoustic Guitar I can see 125 kbit/s audio, which is the reduced rate. The bitrates are actually 192 and 125 abr, as reported by, for example, ffdshow, which shows the instantanenous and average readings. Some new videos do still use the higher rate, and there doesn't seem to be any clear reason why one should get the higher, and another the lower. For example, 125 kbit/s, 192 kbit/s, 192 kbit/s. I noticed that one video changed from 192 down to 125 today. Maybe there is a mixture of quality on the YouTube network, and it depends on where the video happens to be served from.

I'm pretty sure the compression comment was in regards to dynamics rather than data, BTW; not that the two don't get conflated.

Don't ask me why I'm even putting this silliness back on the table.
