ACCEPTED FORMATS
The App converts most video and audio input types of files, like: MP3, MP4, WMA, FLAC, AMR, CDA, OGG, AVI, WMV, AIFF, FLV, WAV, MPG, ASF, MPEG, MPE, MOV, 3GP, M4V, MKV, MOD, OGM, DV, VID, and others.
CUSTOMIZATION OF MP4/M4A FORMAT
The Converter supports MP4/M4A output format with AAC and ALAC codecs:
- AAC-LC (Low Complexity AAC) provides high-quality encoding, which is the most efficient and widely used, and is therefore selected by default.
- AAC-HE v1 (High-Efficiency AAC v1) - provides medium-quality encoding at lower bitrates for mobile and broadcast applications.
- AAC-HE v2 (High-Efficiency AAC v2) - provides medium-quality encoding for lower bitrates with the use of Parametric Stereo technology. It should be used for mobile devices, broadcasting, and other domains where CD-quality is not essential.
- ALAC (Apple Lossless Audio Codec) - This is the only lossless codec natively supported by iTunes and iOS devices.
By default, automatic settings are selected, which ensure the best possible audio quality by avoiding unnecessary resampling and remixing. However, if need be, customized fixed settings for Sample Rate, Channels, Bit Rate, Bit Rate Mode, VBR Quality, Bit Depth, Compression Level, and Codec can be applied.

IMPROVEMENT OF SOUND
Enjoy high-quality sound through premium conversion thanks to the built-in volume adjuster and audio effects. The Volume adjuster amplifies the volume of sounds that are too quiet or the parts of sounds, such as speech and voices. Audio effects include fade-in, fade-out, and trimming of silence at the start and end of tracks. Enabling audio effects like Fade In and Fade Out ensures a clean and seamless transition between songs.

TRUE BATCH PROCESSING
This Mac app can encode an unlimited number of media files and folders at once. Just drag and drop your audio and video for conversion. The app will keep the folders' structure, original tags, and file names for all output MP3s. You will be provided with detailed progress reports on the conversion of every file and notified when all file encoding is complete.
EXTRACT MULTIPLE AUDIO TRACKS FROM VIDEO
The app separates and converts all audio streams from a video into M4A format. Some video files, such as MP4, WMV, AVI, and MKV, contain a few audio tracks. There could potentially be multiple language tracks or audio for various types of hardware. The majority of MP4/M4A encoders capture only a single audio track, which is defined as the main track by the movie's creators. Even so, if you would like to extract all audio tracks from a video, you will need to use a specialized application. To M4A Converter is an ideal tool for such an occasion – it rips every audio stream from a video. Thus, you only have to choose which audio stream you prefer, as you will have access to all of them.
CONVERSION IN 2 CLICKS
To convert media files to MP4/M4A format, select a destination folder and drag and drop your files or folders into the app's icon or interface. Converter will notify you when processing is complete, and if any failures have occurred during the conversion. The Convert utility is "crash-free."
TAGGING
To M4A Converter supports the transfer of tags from source files to output M4A or MP4 files, allowing the conversion of source WAV Info, ID3, XIPH/Vorbis, and other metadata formats into MP4 tags embedded in output M4A files. You can also enjoy better-organized music thanks to loading missing MP4 tags from online databases or local folders and file names.
**NOTE: DRM protected audio and VOB files cannot be converted due to App Store policies.
