Amadeus Lite 2.1

Use your Mac for any audio-related task, such as live audio recording, creating iPhone ringtones, digitizing tapes and records, converting between a variety of sound formats (including Mp3, Mp4, AIFF, WAVE, FLAC, Ogg Vorbis), remastering your iTunes music library, etc.

Thanks to its outstanding direct-to-disk abilities and waveform caching, edits on arbitrarily large sounds are performed at lightning speed. The handling of large sounds is furthermore facilitated by the extensive support of markers.
While Amadeus Lite features a number of built-in audio effects (equalizer, speed and pitch change, echo, etc), its abilities can be extended arbitrarily by the support of Audio Units.
