Amadeus Pro from HairerSoft may be one of the most often used audio recording and editing applications on the Mac platform, at least by casual and semi-professional recording engineers. Amadeus Pro's capabilities allow you to create single or multi-track recordings, and then use the many editing tools to enhance your creation.

Amadeus Pro
The recording process is easy to set up. Amadeus Pro will use your Mac's built-in audio channels, both analog and digital, plus any audio source your Mac is able to recognize. This makes creating your own studio both a pleasant and easy task. Amadeus will configure itself to recognize any of the audio sources you may have.
Amadeus Pro supports a wide range of audio file formats, including MP3, AAC, Ogg Vorbis, Apple Lossless, AIFF, Wave, and many others. You can also use Amadeus Pro to batch process audio files, letting you mass convert from one format to another. You will also find a wide collection of effects, using either Audio Units or VST audio plug-ins. With support for these two standards of audio plug-ins, you can extend and customize Amadeus Pro to meet just about any need you will encounter.
Whether you want to convert vinyl or tape to digital, or create your own home studio, Amadeus Pro can be the go-to application for your audio needs.
Amadeus Pro is $40.00. A 30-day demo is available.
