Amadeus Pro lets you use your Mac for any audio-related task, such as live audio recording, digitizing tapes and records, converting between a variety of sound formats, etc. Thanks to its outstanding direct-to-disk abilities and waveform caching, edits on arbitrarily large sounds (even beyond the usual 2GB limit) are performed at lightning speed.
