Audio signal watermark

- when the mse is zero, then the psnr will be infinity , but in the programming the range of the psnr values between (0-100). If the value go to the 100 then good quality, else if the value go to zero then poor quality

min psnr is zero

max psnr is 100

- according to the second part of question

yes, may be the values greater than 40dB
