Scanner audio has an SNR of about 40dB on a good day. Bandwidth is about 4KHz.

It is way better than those. Thank you! That sounds like exactly what I was looking for. No point in perfect killing off very good. Most of the sound improvement one gets after the samples get wider than 16 bits per channel is inaudible unless one has extremely good ears and the sound source is free of noise.
