MP3 Encoder is a high-speed batch MP3 conversion tool designed to run on macOS. You can batch import numerous audio files, customize conversion parameters, and the software leverages a high-quality LAME encoder to perform multi-threaded transcoding using all CPU cores in your computer.
Key Features:
1. Multi-threaded batch MP3 conversion based on the LAME encoder, allowing you to freely combine encoding methods, bitrates, audio quality algorithms, and stereo modes.
2. Smart file recognition: Determines audio formats based on file content, ensuring normal import even if the file extension is incorrect or missing.
3. Support for raw audio files: Enables importing of .raw, .pcm files, as well as SD2 audio files with damaged resources, and allows manual setting of sample rate, bit depth, and channel count.
4. Preserves metadata: Original file tags can be automatically adapted and synchronized to the converted MP3 files.
5. Supports multi-value tags: Multiple content tags such as composer, artist, and album artist can be displayed and saved normally, and custom multi-value separators can be set in the settings.
6. Pure tag editing mode: Allows direct modification of existing MP3 file metadata without retranscoding.
7. Custom output file names and paths: Allows setting of output paths and file names based on metadata such as artist, album, and track number.
8. Flexible sampling rate conversion and bit depth jitter: Offers professional, standard, and fast sampling rate conversion options, along with various bit depth noise reduction schemes.
9. Automatically adds converted MP3 files to the system music app.
10. Native support for Apple’s custom chip architecture.
Supported source file formats:
Supports 3GP audio, 3GPP-2 audio, AAC, AIFF, AIFC, Apple lossless format, Core Audio format, DSD (DFF/DSF), FLAC, module audio (MOD, S3M, XM, IT, etc.), MP3, Musepack, NeXT/Sun audio, Ogg FLAC, Ogg Speex, Ogg Vorbis, Opus, raw PCM, real audio, real media, SD2 audio, True Audio, WAV, WavPack, Windows Media Audio.
