Size Comparison Chart of Various Formats DSD-WAV-FLAC-mp3

If you've ever wanted a rough guide as to the size of a DSD file compared to a WAV or mp3, here is a chart created by Romain Delbos and Quentin Brard, recording engineers from France.  The chart compares a 5 minute stereo sample in all the formats.  Interesting to note that CD quality (44.1k/16 bit) wav files are about 10 times larger than the 128kbps mp3 files sold on amazon and DSD64 is 40x bigger than an mp3 at 128kpbs.  

Of most interest to audiophiles would be that 192k/24 bit PCM wav files are larger than DSD64.  Meaning that delivery of the 192 PCM wav file would take longer than the DSD64 download.  This could be an interesting reason for DSD to be the 'container' for sending out large files of PCM, like DXD.

Note: we are updating our current Size Comparison Chart to give you more accuracy with FLAC file sizes. Sizes of FLAC files can vary depending on music dynamics, conversion tool used, format the file was converted from and level of compression (or uncompressed) used.
