SV8 beta speed testing

Besides confirming that this Musepack version encodes and decodes faster than ogg (ogg2.83-aoTuVb5), aac (Nero Digital™ Audio+ 1.1.34.2) and mp3 (lame3.98b5) by at least 20% (Intel Core2Duo at 3 GHz) I have compared mentioned encoders at bitrates around 130-135 kbps (q 0.4 and -V4 -V5) using 4 albums of pop and disco genre. My own tests:HARDWARE SETTINGS : • Intel Core2Duo E6300 • MSI-7318 motherboard • 2x512 MB DDR (533 Mhz?) • 320 GB HDD, partitioned and defragmentedSOFTWARE SETTINGS : • test file : 9:58.933 (26412960 samples) • encoding GUI & speed values: foobar2000 0.9.4.5b • encoders: see complete log files for informationNOTE : The test is restricted to the encoders I already have on my harddrive. Three different categories of settings: - portable bitrate (~130 kbps) - ultra-high lossy bitrate (~320 kbps) - lossless (only WavPack & FLAC) I performed three encodings for each setting and I kept the fastest one.Most important : these results applies for one single file encoding . One core is used (excepted for Vorbis LANCER, which is the only multithreaded audio encoder available).RESULTS : FRIENDLY BITRATE ENCODER SPEED BASIS¹ BITRATE ------------------------------------------- AAC Nero 21.97x 93 129 kbps MP3 Fraunhofer 43.75x 185 144 kbps MP3 LAME 20.03x 85 139 kbps MPC SV8 23.57x 100 160 kbps Vorbis Lancer MT 72.32x 307 138 kbps Vorbis Lancer 50.90x 216 138 kbps PARANOIAC BITRATE ENCODER SPEED BASIS¹ BITRATE ------------------------------------------- AAC Nero 17.77x 75 332 kbps MP3 Fraunhofer 109.83x 466 320 kbps MP3 LAME 17.34x 74 320 kbps MPC SV8 21.57x 92 385 kbps Vorbis Lancer MT 69.57x 295 312 kbps Vorbis Lancer 48.39x 205 312 kbps WavPack lossy 68.93x 292 343 kbps LOSSLESS ENCODER SPEED BASIS¹ BITRATE ------------------------------------------- FLAC -0 206.03x 874 760 kbps FLAC -5 99.82x 424 723 kbps FLAC -8 29.08x 123 719 kbps WavPack -f 126.09x 535 747 kbps WavPack 106.19x 451 726 kbps WavPack -h 80.87x 343 720 kbps WavPack -hh 65.30x 277 713 kbps ¹ MPC SV8 beta --quality 4 = 100 basis (example: AAC Nero (~130 kbps) is ~7% [0,93 or 100-93] slower than musepack (~130 kbps) but WavPack lossy is 2,92x faster. MPC is slightly faster (7...15%) than Nero AAC and LAME, but much more slower than Vorbis (up to 3 time faster), Fraunhofer MP3 (4.66x faster at high bitrate), WavPack lossy (~3x faster) - and abysmally slower than true audiophile (lossless) encoder (up to ~9x slower). In other words LAME, Nero Digital and MPC's are more comparable to turtles than rabbits. Musepack is in 2007 anything but a fast encoder¹ (unlike in 2001, golden age of the format) but is indeed less slow -consolation- than two big competitors Musepack is really THE speed king ...Yes, in the kingdom of turtles and snails Anyway, congrats to the MPC developers - though SV8 only adds some fundamental stuff (seeking, possible video muxing) other formats got for a decade.
