Hi all,

For the last few weeks I've been busy writing a new lossless audio codec comparison, after lots of talk about it here and here.

The full test report can be found here (PDF), the raw data and graphs can be found here (zip).

While the full report has lots of graphs it also has lots of text, so the 'main' graphs of the report are posted below.



The CDs used
  • 30 Seconds to Mars - This Is War (rock)
  • Confido Domino Minsk - Sacred choral music from White Russia (choral, religious)
  • Daft Punk - Alive 2007 (electronic, live)
  • Dan Brown - Angels and Demons (audiobook)
  • Enya - Amarantine (new age)
  • Fanfare Ciocarlia - Baro Biao: World Wide Wedding (world music, brass)
  • Gilberto Santa Rosa - Esencia (salsa)
  • Giuseppe Verdi - Messa da Requiem (Berliner Philharmoniker feat. conductor Claudio Abbado) (classical, romantic)
  • Howard Shore - The Hobbit: An Unexpected Journey (soundtrack, orchestral)
  • Iron Maiden - Brave New World (metal)
  • John Coltrane - Live at the half note, vol. 1 (jazz)
  • Joss Stone - Mind, Body & Soul (soul)
  • J.S. Bach - Magnificat (orchestral, baroque)
  • Koninklijke Militaire Kapel - [no name] (military brass, vinyl rip)
  • Kraftwerk - Autobahn (electronic)
  • Lana del Rey - Born to Die (pop)
  • Lil Wayne - Tha Carter III (hip hop)
  • Martin O'Donnell & Michael Salvatori - Halo: Reach O.S.T. (ambient-ish, soundtrack)
  • Michael Bublé; - meets madison square garden (pop, live)
  • Mike Oldfield - Tubular Bells (not classifiable)
  • Rosenberg Trio - Djangologists (jazz)
  • Rush - Grace under Pressure (1997 remaster) (rock)
  • System of a Down - Mezmerize (metal)
  • Szakcsi - Virágom, virágom (world music)
  • Tiësto - In Search of Sunrise 7: Asia (dance)
  • Various - Jeff Waynes Musical Version of The War of the Worlds (radio drama-ish, rock, orchestral)
  • Various - Latin Village, CD 1: Salsa (compilation of salsa)
  • Xzibit - At the Speed of Life (hip hop)
  • Yann Tiersen - Le Fabuleux Destin d'Amélie Poulain (minimalism, soundtrack)


For more information on why I chose these CDs, what strange things happened with the pure speech data (Dan Browns audiobook) and tests on 96kHz/24-bit or surround sound audio, check the full report.

Its labeled revision 1 because I intend to keep it updated. Any comment (on my grammar too, as I'm not a native speaker) is welcome.

I know lossless audio codec comparisons have lost interest with most of you, but only one reply? I hope that PDF wasn't too overwhelming. rolleyes.gif

Anyway, a short version of this comparison (and the PDF) is on the FLAC website now: http://flac.sourceforge.net/comparison.html
