AudioCupcake1.0.19

Drag a finished WAV or AIFF recording onto AudioCupcake to automatically master it for audiobook narration or podcast publication. Its one-step processing applies RMS normalization from -18 to -23 dB RMS, the level range used for ACX delivery and other listening destinations. The drop-based workflow takes a recorded and edited performance through mastering without requiring additional controls for the basic operation.

The free version provides RMS normalization, while Premium adds peak normalization at -3.0 dB. Premium also exports 192k mono MP3 files ready for uploading to an ACX project. A Go Premium button stays in the main window, allowing the upgrade to be completed in two clicks within the app.

AudioCupcake is aimed at Mac-based audiobook narrators, producers, and podcasters who want a quick finishing stage after editing their audio. It is useful for preparing spoken-word files consistently before delivery, especially when ACX specifications matter. Help and FAQ materials are available for users who need guidance. The software runs on macOS, with version 1.0.19 supporting both Intel and Apple Silicon, and it is offered as freeware with the Premium edition available as an upgrade.
