Random-noise on MATLAB with varying amplitude and frequency

I would like to create 'random' noise on MATLAB with the following characteristics:

• continuously changing frequency within a spectrum of 0.1-640 Hz.
• varying amplitudes in the range -1 to +1, drawn from a normal
  distribution with mean 0 and variance such that 99% of values = range ±1.
• I would like the amplitude to change with each frame, where the sampling rate is 1280 frames per second.
• In the frequency domain, all coefficients of the random sequence must have a similar size ("white noise").

Thank you for any help you can provide.
