Re: [LAU] Sine Wave Generator - Linux-audio-user

 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?

Start the snd-ls sound editor[1] and paste the following code into the 
terminal:

(<rt-out> (oscil :freq 1000))

   Set volume:

(<rt-out> (* 0.01 (oscil :freq 1000)))
