minimp3 ========== Minimalistic MP3 decoder single header library. It's designed to be small, fast (with sse/neon support) and accurate (ISO conformant). Here is rough benchmark measured with perf (i7-6700K, IO included, no CPU heat to address speedstep): | Vector | Hz | Samples| Sec | Clockticks | Clockticks per second | PSNR | Max diff | | ----------- | ----- | ------ | ------ | --------- | ------ | ------ | - | |compl.bit | 48000 | 248832 | 5.184 | 252421*** | 4.869M | 124.22 | 1 | |he_32khz.bit | 32000 | 172800 | 5.4 | 16148873 | 2.990M | 139.67 | 1 | |he_44khz.bit | 44100 | 472320 | 10.710 | 41977782 | 3.919M | 144.04 | 1 | |he_48khz.bit | 48000 | 172800 | 3.6 | 16127***4 | 4.479M | 139.67 | 1 | |hecommon.bit | 44100 | 69120 | 1.567 | 6133060 | 3.913M | 133.93 | 1 | |he_free.bit | 44100 | 156672 | 3.552 | 12423560 | 3.496M | 137.48 | 1 | |he_mode.bit | 44100 | 262656 | 5.955 | 18489271 | 3.104M | 118.00 | 1 | |si.bit | 44100 | 135936 | 3.082 | 13070375 | 4.240M | 120.30 | 1 | |si_block.bit | 44100 | 73728 | 1.671 | 7148739 | 4.275M | 125.18 | 1 | |si_huff.bit | 44100 | 8***00 | 1.959 | 8595200 | 4.387M | 107.*** | 1 | |sin1k0db.bit | 44100 | 725760 | 1***57 | 55247025 | 3.357M | 111.03 | 1 | ## Compare with keyj's [minimp3](http://keyj.emphy.de/minimp3/) Feature compare: | Keyj minimp3 | Current | | ------------ | ------- | | Fixed point | Float point | | source: 84kb | 68kb | | no vector opts | sse/neon intrinsics | Keyj minimp3 benchmark/conformance test: | Vector | Hz | Samples| Sec | Clockticks | Clockticks per second | PSNR | Max diff | | ----------- | ----- | ------ | ------ | --------- | ------ | ----- | - | |compl.bit | 48000 | 248832 | 5.184 | 31849373 | 6.143M | 71.50 | 41 | |he_32khz.bit | 32000 | 172800 | 5.4 | 26302319 | 4.870M | 71.63 | 24 | |he_44khz.bit | 44100 | 472320 | 10.710 | 41628861 | 3.886M | 71.63 | 24 | |he_48khz.bit | 48000 | 172800 | 3.6 | 25899527 | 7.194M | 71.63 | 24 | |hecommon.bit | 44100 | 69120 | 1.567 | 20437779 | 13.039M | 71.58 | 25 | |he_free.bit | 44100 | 0 | 0 | - | - | - | - | |he_mode.bit | 44100 | 262656 | 5.955 | 30***8***4 | 5.203M | 71.78 | 27 | |si.bit | 44100 | 135936 | 3.082 | 24096223 | 7.817M | 72.35 | 36 | |si_block.bit | 44100 | 73728 | 1.671 | 20722017 | 12.394M | 71.84 | 26 | |si_huff.bit | 44100 | 8***00 | 1.959 | 21121376 | 10.780M | 27.80 | 65535 | |sin1k0db.bit | 44100 | 730368 | 16.561 | 55569636 | 3.355M | 0.15 | 58814 | Conformance test fails on all vectors (PSNR < 96db), free format is not supported.
