Good dedicated reverb options
So I've been recording a piano quartet, mics on the close side (>10 feet from instruments). The result is nice but a touch of reverb is required to simulate/create a world-class concert hall.
Can you experts recommend good reverb effects? Details appreciated, and if there are any good open source reverb programs, I'd be thrilled to check them out (though i doubt it, if even stuff like Soundforge have reverb that to me sounds totally artificial).
