Would it be possible for you to recollect your statistics for modes 2 - 4 with the latest Git master version? If you're short on time, doing that only for mode 3 would also be fine. Hi, thank you for your reply. I have no problem with measuring the bitrate evolution. I add mode 1 and mode 6 in the table (with exhale 1.03, before change) :ENCODER PRESET | BITRATE | STEREO | FULL SET | MONO LOW BITRATE HIGH BITRATE | (91 CD) | (3 CD) (4 CD) (3 CD) ------------------------------------------------------------------------------------ FLAC CUEtools -8 | 580.2 kbps | 467.7 kbps 264.0 kbps 1028.7 kbps ------------------------------------------------------------------------------------ exhale 1.0.3 x64 mode 1 | 61.1 kbps | 61.7 kbps 38.3 kbps 72.0 kbps exhale 1.0.3 x64 mode 2 | 80.6 kbps | 85.7 kbps 54.3 kbps 96.0 kbps exhale 1.0.3 x64 mode 3 | 99.3 kbps | 100.7 kbps 62.8 kbps 115.0 kbps exhale 1.0.3 x64 mode 4 | 110.5 kbps | 110.0 kbps 67.5 kbps 126.7 kbps exhale 1.0.3 x64 mode 5 | 131.2 kbps | 123.7 kbps 77.3 kbps 145.3 kbps exhale 1.0.3 x64 mode 6 | 143.4 kbps | 130.7 kbps 82.5 kbps 157.3 kbps I'm currently running a batch encoding for mode 3. Twenty albums are already encoded. The trend is that stereo discs are now slightly smaller (-3 kbps on average for the first discs) and mono discs drop from 100.7 kbps to 81 kbps. It's still a bit higher than all competitor I tested but it's way better I'll continue the test
Wavpack Hybrid: one encoder, one encoding for all scenarios WavPack -c4.5hx6 (44100Hz & 48000Hz) ≈ 390 kbps + correction file WavPack -c4hx6 (96000Hz) ≈ 768 kbps + correction file WavPack -h (SACD & DSD) ≈ 2400 kbps at 2.8224 MHz
