Re: Can lossy high resolution outperform lossless at standard resolution?

The first world problem, huh? Okay, let's put this question into perspective, because snake oil is infinite, to paraphrase the quote attributed to Albert Einstein , and 192 kHz is no longer the limit of what you can encounter. Here is a modern music cover that informs the source comes with a sampling rate of 352.8 kHz. And below that we see a piece of not so über-expensive audio equipment that claims to handle even 768 kHz. Since Vorbis cannot climb that high, it's no longer an option. Raise the fist and draw some air: WavPack, WavPack, WavPack! Because it supports sampling rates up to 1 GHz, right? Let's take some 4 minutes 192 kHz 24-bit song, process it with SoX resampler DSP if necessary, and witness how WavPack 5.70 -b4x3 hybrid (without correction files) scales. Bytes BPS Filename ------------- ------ ----------------- 11 046 164 373 44100.lossy.wv 12 001 612 406 48000.lossy.wv 21 792 564 737 88200.lossy.wv 23 802 134 805 96000.lossy.wv 43 732 116 1479 176400.lossy.wv 47 616 420 1611 192000.lossy.wv 88 388 268 2990 352800.lossy.wv 204 902 192 6933 768000.lossy.wv The output grows, no surprise there. So it's just a matter of time before lossy files that preserve that Burj Khalifa sampling rate and Kola Borehole bit depth of the source force you to worry about free space again. That is, what you are experiencing now with bloated lossless files will happen later with bloated lossy files. As Karl Marx put it, “first as a tragedy, then as a farce”. The good news is you have a hunch on how to proceed.Downsizing 24/96 and 24/192 to 16/44 or maybe 16/48 seems to be the obvious choice. This. And you'll still be able to hear the owl flying by , if, of course, the microphone captured it in the first place.
