CAN we re-create the "vinyl sound"

Welcome to the beautiful world of real instruments.... I've played piano, started at the same age [span style='font-size:14pt;line-height:100%']Theory:[/span] 64 kHz is the maximum measured harmonic frequency coefficient generated by any instrument. (mostly brass) (I've read it in some old book... can't quite remember which was it, so don't quote me) High frequencies might interfere with lower frequencies... but do you have an equipment to generate 32 kHz tone? I guess not. Even most 'adiophilistic' equipment has a frequency range of maximum 24 kHz. So there is no perfect reproduction of instruments. Additionally, PCM method might not be the best for our ears to represent analog audio. All sound recordings (not only digital) use properties of our hearing to conserve space. [span style='font-size:14pt;line-height:100%']Practics:[/span] If 44,1 kHz is not enough, 48 kHz might be... 96 kHz is an overkill, as is 24bit audio. This only adds margin to avoid rounding errors in processing. 16bit might be too little, so record as 24 bit/48000Hz, then add dithering&downsample to 16bit to keep most of additional dynamics. Then you should be able to compress it well. If you can ABX between 24bit audio and dithered 16bit, then only choices left are WavPack lossy or any lossless codec. <edit> Slight modifications to interpunction. </edit>
I've changed only because of myself. Remember, when you quote me, you're quoting AstralStorm. (read: this account is dead)
