Yesterday evening I purchased the MacHeist 3 bundle. Primarily this was to pick up a copy of Wiretap Studio. Audio Hijack would have been slightly cheaper than the $39 bundle. However, some of the other applications look rather interesting so I jumped in. It would be splendid if Espresso were unlocked.
I have already used Wiretap Studio to convert a couple of old cassettes into MP3 format and am quite pleased with the results. The rest of the more interesting cassettes should follow suit, perhaps over the weekend.
