Compression ratios
A compression ratio estimate:
- 7333 audio files, (in 429 folders), winamp: 14 days+14:25:43
- wav - 207 GB (223.171.483.886 Bytes)
- flac 1.1.2, 1.1.3 - ca. 89,0 GB (95.627.346.550 Bytes) ratio = 0.428492677
- flac 1.2.1b - 86,3 GB (92.729.301.460 Bytes) ratio = 0.415506945
- wav - 207 GB (223.171.483.886 Bytes)
# of files | GB | playing time |

File size
Average tango file per above sample is
- wav
- 223 171 483 886 / 7333 = 30 433 858.4 byte
- (223 171 483 886 / 7 333) * 8 = 243 470 867 bit
- flac
- 92 729 301 460 / 7333 = 12 645 479.5 byte
- (92 729 301 460 / 7 333) * 8 = 101 163 836 bit ~ 100 Mbit
Data security
2008-02-20 User:Chrisjjj : For me most important is security of data. I have seen programs such as MediaMonkey have only recently had fixes to bugs that corrupted FLAC files so, though not the fault of FLAC, sadly I think more time is needed before FLAC is as safe to use as older formats.
