3 bit Louder sample for testing if problems still are the same when louder:
I don't know you can call this process lossless but since it is reversible in my little tests it may the right word for this case.

1 bit in dB equals:

20 x log10(2) = 6.020599913

Using gain with SoX it starts from 6.0205999 on to shift the music around bit by bit! One digit less and it calculates new values with no chance to reverse it back to original. With a negative value you can make it exactly 1 bit softer.

On this sample i used 3x

sox -D input.wav output.wav gain 6.020599913
