vaguely rings a bell. more recently ive seen SDR-Widget, as radio is quite demanding of ADC noise-floor quietness, flatness - eg most Intel HDA cards are not really capable of 192khz sampling with a fixed ~22KHz brickwall LPF (prevent aliasing at low samplerates) which isnt switched to a different LPF at higher rates (cost reasons presumably) and even "good" cards like emu 0202 could be improved upon..
