SuperFast multithreaded LAME MP3 encoder — parallel libmp3lame instances + bit-reservoir repacker, roughly 8× faster than stock single-threaded LAME at the same quality.

Features

  • Encoder: LAME 3.101 beta 3 (r6531) + maikmerten q4 fix; CBR / ABR / VBR
  • SuperFast MT: parallel encode + bit-reservoir-correct repacker (self-healing fallback)
  • CPU dispatch: one binary, four CPUID-selected engines — znver5 / znver4 (AVX-512) / znver3 (AVX2) / x86-64 (SSE2)
  • Input: WAV, AIFF, and FLAC (multithreaded decode, up to 24-bit); full-precision float pipeline
  • Decode: MP3 → WAV via libmpg123 (--decode)
  • Resampling: r8brain (linear-phase, ~207 dB), parallelized
  • Tags: ID3v1/v2 UTF-8, album art (--ti, JPEG/PNG); FLAC tags + cover auto-imported
