General Audio / Re: Can lossy high resolution outperform lossless at standard resolution?
Last post by .halverhahn -If I summarize:Slight misscalculation in your table: 54kHz Samplingrate = 27kHz bandwidth = +5000 Hz over RedBook
At the moment, the possible formats of choice are:
- FLAC: resampled to 48000 and 20 bit = 1000 kbps. Not bad. A few improvements over Red Book (+4000 Hz, +4bit) and decent bitrate. No fear of artifact or noise
- FLAC: resampled to 54000 and 19 bit = 1000 kbps. Not bad either (+10.000Hz and +3bit over RedBook).
- FLAC: resampled to 54000 and 18 bit = 900 kbps. (+10.000Hz and +2bit over RedBook).
I woulnd't use odd non standard samplingrates. There is a quite big chance that your sound-hardware isn't supporting it.
To test it for support, set foobar output to exclusive mode.
To playback odd rates additional resampling is required by the player or OS.

I tried then 60000 Hz, 58000 Hz, 56000 Hz, 52000 Hz => output file is always 192.000 Khz. Is it a bug or a feature? Probably a bug.Windows "Primary Sound Driver" is resampling it to the standard samplingrate you're set up in your sound settings.

As you paid a Premium for your 24/192 Files, I would go to 24/96 or 20/96 to save space and to be still in the area of peace of mind.
- Keeping 192.000 Hz is a total waste of space: no information but noise on all recordings I tried (and most of them are modern and state-of-the-art recordings from the last three years
- 96.000 Hz is from an perceptual point of view the same waste, but from a technical point of view the upper frequencies contains real information (but of course not audible)
