Take a look at sox. Eg, the following from 'man sox',
,-----
| synth [-j KEY] [-n] [len [off [ph [p1 [p2 [p3]]]]]] {[type] [combine]
| [[%]freq[k][:|+|/|-[%]freq2[k]]] [off [ph [p1 [p2 [p3]]]]]}
| This effect can be used to generate fixed or swept frequency
| audio tones with various wave shapes, or to generate wide-band

|
| For example, the following produces a 3 second, 48kHz, audio

| sox -n output.wav synth 3 sine 300-3300
| and this produces an 8 kHz version:
| sox -r 8000 -n output.wav synth 3 sine 300-3300
