Recorder for Notes will let you record all of your notes in the Notes application, and turn them into audio files using the Mac's built in speech technology.
Features: Recorder for Notes will consolidate and record all of your notes with pauses and time stamps between entries. Audio files will be recorded in the voice that you have selected in the Speech Control Panel. Supported output audio formats are AAC and AIFF. While AAC is preferred because of it's significantly smaller file size, some 3rd party voices may not support it. For that reason, AIFF is included as well.
