Get beautifully mastered audio, automatically.

AudioCupcake gives Mac-based audiobook narrators, producers and podcasters a simple, beautiful mastering tool that makes your audio sound spectacular.

Go from good performance to great performance.

Record and edit your finished audio, then use AudioCupcake to make it great, with proper RMS normalization for ACX (and everyone else).

And with the Premium version, you get peak normalization and MP3 file output.

Drag and drop your files in one move.

All this gooey goodness takes just one drag of your WAV or AIFF files, and just one drop onto AudioCupcake. Nothing else you need to do, except enjoy how easy it is.

Come for the RMS, stay for the MP3.

We don’t stop there. AudioCupcake comes in two delicious flavors:


  • -18 to -23 dB RMS normalization.

PREMIUM VERSION (one time payment of $19.95):

  • -18 to -23 dB RMS normalization.
  • -3.0 dB peak normalization
  • 192k mono MP3 file output, ready for uploading to your ACX project.
