To Audio Converter

About

To Audio Converter for Mac converts audio to MP3, WAV, FLAC, AIFF, and M4A/MP4. You can use automatic settings, which analyze the source audio and choose the bit rate and compression level, or customize the audio codec, bit rate, channels, sample rate, and quality yourself. The app accepts over 200 audio and video formats, online multimedia, playlists, and Internet shortcuts, and it can also accept unknown file formats through drag and drop.

Batch conversion is built for large collections. You can drop entire folders or hundreds of gigabytes of media into the app at once, run multiple conversions simultaneously, and keep the original directory structure, file names, and tags. The app can also add converted files to iTunes or create a new iTunes playlist from them. Saving to a custom destination, including an external device, and preserving folder structure are supported, and a CUE Splitter can split albums and DJ sets into single tracks.

Sound improvement tools help make tracks play consistently. You can adjust volume, trim silence, apply fade-in and fade-out effects, and use peak volume normalization, EBU R128 loudness normalization, or automatic volume control for voice recordings. The app is also described as offering tag organizing alongside these sound enhancements.
