Questions tagged [companding]

Companding (sometimes compansion) results from a merge between "compressing" and "expanding". It mitigates transmission, limited-range or quantization effects by combining a compressor function, a (uniform) quantizer, an expander function (inverse of the compressor). It generally better preserve small amplitude samples with respect to large values, intending to retain almost constant (or slow-varying) relative quantization errors.

Is there any python code for applying a-law/mu-law on 3D numpy array?

I have 3D numpy array of probabilities between [0,1], I need to emphasize on some area with lower probabilities. I was suggested to apply a-law and mu-law. I am wondering if there is python library/...

A query on the non-uniform quantization

I have read that non-uniform quantization boosts the smaller amplitude signals by a large amount. However the larger amplitude signals receive a small gain. As shown in the below diagram (Compressor ...
