MP3 Encoder v2.20.0

MP3 Encoder v2.20.0 for Mac

MP3 Encoder by Mark-V Apps is a native macOS utility for batch MP3 conversion using the high-quality LAME encoder—multi-threaded across CPU cores, with full tag editing and flexible output naming.

Version 2.20.0 adds raw PCM import, content-based file detection, richer metadata handling, sample-rate/dither controls, and a refreshed interface.

What’s new in v2.20.0

New:

• Raw PCM & SD2 import — open .raw/.pcm or stripped Sound Designer II files; set sample rate, bit depth, and channels in one sheet
• Content-based detection — recognizes audio by file contents, not extension; “All Files” toggle for extensionless files
• Tag passthrough — source metadata maps across formats into the encoded MP3
• Multi-value tags — Composer, Artist, Album Artist, etc.; configurable Multi-Value Separator (Settings → Metadata)
• Sample-rate & dither — Mastering / Normal / Fast resampling; None, TPDF, or Noise Shaping dither (Settings → Audio)

Improved:

• Refreshed main window; file count as subtitle; rebuilt per-file progress bars

Fixed:

• Album art no longer lost on FLAC files with multiple PICTURE blocks
• Better decoding of multi-channel files without a defined channel layout
