To Audio Converter Free for Mac OS X - is the only app for audio conversion that you need. It converts more than 200 audio and video formats to quality MP3, WAV, AIFF, M4A, MP4 or FLAC in one click. Automatic or fully custom output audio settings, inbuilt CUE splitter, CD ripper, volume normalization and audio effects, tag organiser and integration with iTunes allow converting your favourite music and voice records easily and quickly.
To start conversion just drop files in the application window or icon. By default, the converter encodes audio and video files to MP3 format with automatically calculated Constant Bit Rate, Sample Rate, and Channels. However, you can manage all output audio settings in Preferences - Format window. When the conversion is finished, you can add converted files with preserved music tags, album artworks, and filenames to a playlist in iTunes.
