Coaster is a little freeware direct-to-disk recording utility which writes files in uncompressed AIFF format, suitable for processing in Sample Editing Software or burning Audio CDs (using Discribe or Toast for example).
It features setting of input source, sample rate and sample size, mono/stereo selection, setting of hardware input gain (stereo where available), accurate level meters with headroom indication, clipping detection, automatic recording based on incoming signal level with file splitting, manual file splitting on the fly, balloon help, basic AppleScript support (timer recording script included).
Coaster requires a PPC processor and Mac OS 8.0 or later (Mac OS 8.5 or later recommended). However, Coaster does not work in Mac OS X, not even in Classic.
