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. SUPPORTED SOURCE FORMATS 3GP Audio, 3GPP-2 Audio, AAC, AIFF, AIFC, Apple Lossless, Core Audio Format, DSD (DFF and DSF), FLAC, Module files (MOD, S3M, XM, IT, and others), MP3, Musepack, NeXT/Sun, Ogg FLAC, Ogg Speex, Ogg Vorbis, Opus, Raw PCM, Real Audio, Real Media, Sound Designer II, True Audio, WAV, WavPack, Windows Media Audio. DRM-protected files of any kind are not supported. Streaming RAM files are not supported. Looking to convert to formats other than MP3? Check out Pro Audio Converter, which does everything MP3 Encoder does plus encodes to a wide range of audio formats.

- 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.
