CD's & Vinyls still a compressed format from the original "Master-Recording" Track (s). In the last days I have being playing with WAVe, FLAC & mp3 compressions out of the same CD. Using Audacity on Waveform (db)Mode: Analyzing the files, by overlay them & Zoom-In them all the way up. Bit by bit is not diff. between CD to WAV at 792MB & CD to FLAC at 579MB FIRST ORIGINAL TEST OUT OF 5: Main Source: CD-R: 2 channels: Stereo. File size: 792MB = 78:28:24 mins. (1 big file) Bit rate: 44,100Hz. Bit per sample: 16bit. PCM Note: One single big file (Mix). I also have the 24 tracks version (CD-R) as a "Master". No Edit or CD-RW for me anymore tho CD > WAV: (via MWM) 792MB = the same = 0% Compression. 44,100Hz. 16bit. Note: CD = WAV a 100% bit by bit. CD > FLAC: (via Music Bee) Compression level 5 (default) = 45% Rip speed: 4x + Volume adjustment. 578MB 44,100Hz. 16bit. Note: CD = WAV = FLAC a 100% bit by bit. CD > FLAC: (via Media Monkey) Compression level 8 = 64% 513MB 44,100Hz. 16bit. Note: CD & WAV diff. to FLAC by around 25%. CD > mp3: at 320kbps (via WMP) 179MB = 77.5% ? 44,100Hz. 16bit. Note: CD, WAV & FLAC; so diff. to mp3 by more that 75%. Is like leasing to a similar song, ...but for sure: NO the same song bit by bit. 77.5% ?: [No FLAC parameters as reference] if the CD is 792MB = 100% ..so 1% = 7.92MB 7.92 x 22.5 = 178.2MB = 77.5% Compression Right !? Any comments !?
