[LAU] Sine Wave Generator

[Andrew Bryant]

Hi all,

I have been looking for a simple audio sine-wave generator that 
interfaces with Jack.

Minimum requirement is that it generates 1KHz tone, with level 
predictably controlled from digital peak down to, say -60dB.

The nearest I've come to it yet is ecasound -i tone, driving a mixer.  
This doesn't, however, give  the confidence I need in the output level.

Any suggestions?

Andrew.
