MP3 Encoder
macOS / Musique
MP3 Encoder is a fast, batch MP3 encoder for macOS. Drop in dozens of audio files, pick your encoding settings, and let it run multi-threaded across every CPU core using the high-quality LAME encoder.
HIGHLIGHTS
• Multi-threaded batch MP3 encoding with the LAME encoder. Pick any combination of encoding method, bitrate, algorithm quality, and stereo mode.
• Smart content-based file detection. Audio files with the wrong extension, or no extension at all, import correctly.
• Raw and headerless audio support. Drop a .raw or .pcm file, or a Sound Designer II file whose resource fork has been stripped, and supply sample rate, bit depth, and channel count in a single sheet.
• Source-file tags pass through to the encoded MP3, with cross-format equivalents mapped automatically so metadata carries through the conversion intact.
• Multi-value tag support. Fields like Composer, Artist, and Album Artist that carry multiple values in the source file are joined for display and split back into multiple values on save. A new Multi-Value Separator setting (Settings, Metadata) lets you pick which separator to use.
• Tag editor mode. Update metadata on existing MP3 files without re-encoding.
• Custom output naming. Build output paths and file names from metadata fields like artist, album, and track number.
• Configurable sample-rate conversion (Mastering, Normal, Fast) and bit-depth dithering (TPDF, Noise Shaping) when source audio needs resampling.
• Optional automatic add of encoded MP3s to the Music app.
• Native Apple Silicon support.

Quoi de neuf dans la dernière version ?
- Now recognizes recovered Sound Designer II files that arrive with a ".sd2f" extension.
- When writing metadata, you're now warned before tagging a queue that mixes MP3 and non-MP3 files, and non-MP3 files are skipped instead of reported as errors.
- Damaged or partially downloaded files now stop with a clear error instead of quietly producing a near-empty file.
- A failed save no longer deletes the existing file at the destination without putting a new one in its place.
- When a save replaces an existing file, the old version now reliably goes to the Trash, even when its name contains spaces.
- Interrupted conversions no longer leave large temporary files behind, and any leftovers from an earlier crash are cleared at the next launch.
- Fixed an issue where certain files could fail to encode on older versions of macOS.
