It would be nice if there were a single standard for audio and video files that worked on every app, every device, and all the time. In the world of constantly changing standards and technological improvements, that’s not likely to happen any time soon. In the meantime, those of us who work on audio and video files need ways to convert from one file format to another.
For Mac audio, I found two easy ways to convert audio files. One is free, one is not, but both are quite good.
First on my list is iSonics which is mostly drag and drop. Select the output audio file format you want, drag and drop the original file, and the rest is easy, but with plenty of options.
iSonics can convert MP3, MP2, AAC, FLAC, ALAC, WMA, OGG Vorbis, Opus, AC3, AIFF, WavPack and WAV and maintains metadata where needed. It even imports audio from CDs and converts the audio tracks to any of the listed formats, and can dump files into iTunes. Some audio processing is built-in, including loudness normalization, peak normalization, and a few other options. It’s very good considering the nominal price tag.
At the other end of the scale is MediaHuman Audio Converter, which is free, and equally simple to setup and use. It doesn’t convert quite as many audio formats at iSonics, but it converts multiple audio files simultaneously, and sends converted files to iTunes.
There’s also a Windows version of Audio Converter. The interfaces vary, but both are simple to master. Converting batches of audio files is a plus for Audio Converter.
